This reminds you just why a tiny club gig just sounds so damn real when there’s only a vocal PA 🎤❤️
Exactly
Does Indeed (also listening to a band in the rehearsal room)
¡Not great for sound reinforcement providers though!
For medium-sized venues a personal column for each performer can help with a more natural sound image.
These, of course, we have immersive...
Except immersive tries to recreate the experience of sitting around a campfire by using central heating.
@@DaveRat Hi again, sorry if you’ve already stated this elsewhere in the comments. So what would be your ideal situation to try out on a gig? Are you suggesting individual stacks above each performer, firing out into the stadium? It’s a conundrum isn’t it, because when you stand next to Flea and his bass rig on stage or in rehearsals it must be epic. But to reinforce that, without using 8 more bass rig heads and cabinets (rather than PA amps and speakers) wouldn’t be true to that sound. Loving the videos, always good stuff.
Understanding the concepts is the first step. I cover ways to improve usage of stereo systems in several other videos and more info on the member side including ways to do it with subs as well. I think just continuing to read and look into it more and find out which aspects apply to you is the way
Dave I SO appreciate how you explain and talk about things: I'm a 'hands on/visual learner', and with all things music it helps a TON to have it taught that way.
Thank you Alan!
I never forgot Dave's story about humans hearing the sound of ocean waves in stereo. Hence our ears, the most perfect set of speakers in the universe does not hear in mono. He told about creating "imbalances" in the PA to simulate how the ear hears sound in a more natural, pleasant and even richer way. Like there is perfection in imperfection. This video expounds on that story further. I've read many things about audio through my life and this might be the most prolific thing I've ever come across. If the idea of trying to see how sound moves in the air is a crazy thing, count me in Dave. I think you're a genius at this.
Thank you and you get it!!!
I have more to come and some demos as well that may be interesting
Makes totally sense. You downmix 30 sources into two tracks that are going to be reproduced into acoustical nightmare (average venue) and create so many issues in frequency, space, and time domain anyways. Pretending the sound from stereo is somehow going to be more coherent and polished is just insane. Dave, you actually use the venue to downmix the audio, kind of like a acoustical summing box, and everyone gets their own slight variation of the mix. I have to admit it took a minute for me to wrap my head around your concept.
You get it!!! ⚡⚡
I encourage anyone doubting the magnificence of this to see a a concert with a Lacoustics L-Isa system. I recently went to a Bon Iver concert where they used it and I have to say its a completely different experience compared to a normal stereo Pa Concert. Especially on this Large scale of an arena. It was waaaay drier, way more immersive and simply waaay better sounding than anything i've ever seen on a non-open-air-stage that large.
🤙👍🤙
Looking for that opportunity, where Dave is stretching into a full system production
🤙🤙
Very thought provoking and Inspirational. Dave you remind me of Russell Johnson ( Artec Consultants ) an old sound designer from New York. He mixed the room with speakers from the ceiling speakers bouncing off the walls and under the seats in Theatres. He also created zones for sound to be directed to through out the theatre allowing more dimension. He was an FN genius. at that time I was just an assistant and my boss could not get his head wrapped around it and trashed the system and went back to point source and ruined an accoustical gem. Sometimes Senoirity SUCKS, but when my boss retired I worked on my own time rewiring trunklines my boss had cut, I had mamagement come and listen when I finished and everyone was blown away. But when I explained what I had did my Supervisor told me to shut it down and never use it again or it would be his ass on the line for letting it happen. So Sad but true.
Dave I Just Like how you show all of us things. Thanks Amillion we can learn from this. A Big Thank You.
Awesome and thank you Hennie!
I said this kind of thing years ago....nice to know someone feels the same!!!!!! Thank you Dave!!!
🔧🤙🔧
Very inspiring. Thanks for relighting the fir in my belly for thinking outside of the box in audio. Years ago I had my teacher at recording arts school 1980ish Tell me I was insane with some of my questions. And to keep it up. Somewhere along the road of my career I became a me too audio guy both live and studio. The best compliment I always get when is from people who know me for a long time see something new and say hey Kyle was doing that years ago.
Cool cool Kyle!!
I love what you are doing i have been thinking of that. Glad you are ahead
🤙👍🤙
This stuff is so fun, when I took a basic sound engineering class in a community collage 20+ years ago it was just as amazing to think of just how stereo works with our 2 ears to fool us to seeing sounds for all directions. But when then thinking of things like this, like the way the sounds come all out of the one speaker, even if you maybe have a perfect outdoor environment where reflections where not as big an issue, just those sounds coming out the same speakers has to have some impact on the distortions and way these sounds mess with each other. I even have a pretty big collection of 3D home audio I enjoy that is mostly in DTS WAV, but I agree you will never get back to the original sound. I really enjoy your videos!
Thank you Jeff!
Amazing video! I never thought of that! Thank you! My wife is a violin player and I often go to a symphonic concert , now I understand why a Symphonic orchestra sounds so real and 3D live , compared to the same orchestra recorded in a studio and played through a stereo sound system :)
Exactly!!
Was working with a research group that was doing MRIs of disabled elderly brains while inducing stimuli to see if they could get the brain to lite up eventually it lead to using music signals but we also found that stereo made the brain work harder. Since then I have been working on loudspeakers that can form a sound field with 1 speaker and a mono signal. I feel it to be a more relaxing way to enjoy music and it's far more natural than stereo.
Interesting stuff
I really do miss something like a 3-speaker standard. Purely mono stuff goes in the middle, purely stereo stuff goes into the sides. It's a small change, but it would definitely change the sound.
🤙🤙🤙
Thought provoking and fun! Thanks Dave
🤙🔧🤙
This reminds me of what Bose did with the L1 system. Each musician had one instead of being funneled through a PA. Pat Metheny did concert that used the L1s exclusively.
Good Stuff!
I like that setup and design and the sound is quite impressive.
Leads me to believe that every musician should have a dedicated speaker (PA) for their instrument positioned in front of them with the best coverage for the audience possible. I suppose rigging and audience size would be the biggest challenge here. Also, creating an environment where there is no stage volume and using the speaker itself as the source. Every musician on IEM’s. This idea has very much dictated how I approach my gigs. Even if I don’t have ideal circumstances, working towards this has improved the quality of my work. Thanks for your inquisitive leadership, Dave!
There are many things we can do or try for many applications. I think its fun and important to explore more and not take the status quo as the way
I love this topic, Dave. When mixing on a well set up stereo rig for a venue, and with enough time to spare to figure out the nuances and advantages/disadvantages of said rig - I try to reproduce what I see onstage in my mix, just louder. Certainly, there will be compensations, but the goal is to generally change things as little as possible. This does not work with all types of music by any stretch of the imagination. It's strictly a goal to have in mind -when feasible. It's a real treat when I'm able to do a mix like this, but also seldom. My 2 cents... And thanks!
👍👍👍
Such a great summary Dave! This really tells the story of how we still have much work to do in terms sound reinforcement. For instance, the research in concert hall acoustics is quite advanced and we now understand a lot of the subtleties very well, from the perceptual aspect, of what actually matters, to the physical measurements which can predict the subjective perception. It's so interesting to see that an orchestra doesn't need any reinforcement, as it's using exactly what you're talking about, the natural interaction with the room and with the reflections, and it's slightly different for every person in the room. I'm looking forward to seeing what the future holds for sound reinforcement and whether we'll manage to escape the stereo hell anytime soon.
PS. If you need me to send you some interesting research papers I'm more than happy to help out, I'm currently doing a PhD in this field as part of the Applied Psychoacoustics Laboratory (APL) and we're always trying to play around with this out-of-the-box thoughts and ideas.
Awesome and yes! I love all new info and please do send what you wish. Drat@aol.com
You might be the person to ask this. What are your thoughts about an antireverb dsp? Basically if you have a fixed PA in a large hall that would naturally reverberate beyond any intelligibility at volume, could you create a custom room signature to get the audio cleaned up a little as it passes down the hall? Almost like an anti reverb impulse response or a selective noise cancelling. Would love to hear your thoughts. (I was at an event in basically a tunnel and I couldn't hear a thing, which is why I thought of it)
I've seen some work on stuff in that direction. Basso ally it takes manyany speakers, like hundreds for a smallish room with complex processing for each speaker.
Much cheaper and easier to add sound absorbing material.
@@DaveRat I figured the something crazy like that would be required. The location I was in is a historic train station in the Midwest, so I'm going to guess either solution is probably not allowed, but the problem got me thinking.
The best I could come up with is a series of reinforcing speakers down the side paired with microphone/speaker clusters for the anti reverb. Combine that with some fancy ANC software that passes the original signal with a source distance delay taken into account. Or some kind of crazy look ahead signal process where the PA automatically accounts for the reflections and pumps out the out of phase signal just before the actual signal.
Anyways, thanks for all the knowledge you've shared!
It's super complex and requires so many speakers, like 25% of the walls covered with sound sources with an amp and processor for every speaker.
Energy once generated is relatively easy to absorb and very difficult to cancel.
Great... by not using soundsources, but lightsources, you make it clearer to me! Thanks, Dave!! 🙂 You mak me look with an other perspective to soundmixing... we are all being so conservative... do it the old way as being teached in the early days... As a musician I try to experiment, thinking outside the box... as a soundguy I am soooo conservative!!
So thanks for your insights and let me be more creative!! 🙂
⚡🤙⚡
You are absolutely right in your thinking, many years ago, when I was young, I got hold of a 10 band eq 5 bands per channel, and sent each band to it's own 3 watt amp and speaker and used a 50 watt amp as a sub, in the middle, it sounded amazing, so yah, it's all good, great video
👍👍👍 VideoMentary Productions Channel
using a stereo pointsource system in a small venue i sometimes squeeze a dog toy squeakie ball for fun during events. i would totally agree that sounds from multiple sources add to the overall experience. thanks for all the videos.
🤙👍🤙
I liked your thoughts, as you said, they make you think outside the box!😀
Awesome
Very interesting observation, video and thoughts. It would be a great future video the application of your opinions in a real mixing scenario of yours.
Cheers.
Will try and do that
I would add that we are perhaps on the way there with systems like atmos and ambisonics. Let's see, there's lots of road to cover with many different scenarios.
Thanks for putting the lights out of the box!
Very cool and yes, there are systems like Atmos or even sound bars, L-isa, Soundscape and surround that try and create the illusion of sound source locations.
It's tough though as the room reflections from the illusion don't match the reflections that would occur from actual sources in those locations.
Inspiring and always interesting, thanks
👍🤙👍
For decades I've been dreaming about a sound system (theater or surround, call it as you like) in which I have not only left and right but also up (above) and down (below) sound channel. The stereo system was the pinnacle of analog recording (we can safely forget about quadrophonia). In the digital realm the sky is the limit as for the number of audio channels. So, you are perfectly right, for re-creating a live performance every sound source should have it's own channel and by that I mean also loudspeaker. The headphones are another painful story, maybe for some other time 😀🤗
👍🤙👍
I love this video. I think it depends on the scenario you’re going for. In a church setting where the goal is to lead the church/congregation in worship, it’s important for each person to be able to hear all of the vocals. So the vocals need to go through each of the LCR speakers. Now we do have some leeway with the instruments because they help create the atmosphere for the songs they sing. Keyboards are the easiest because they send different sound to each speaker. Guitar is some what simple because the effects can be stereo and send different sounds to each speaker but you can also pan the guitar to mimic where the guitarist is located on stage. Same for bass and drums.
🤙👍🤙
Sind Some time last year doing small pub gigs with 4 point source speakers behind the performers, plus two speakers for ell guitar. Placing every instrument in the speaker behind that that instrument and the fx to the two speakers beside. Was a very interesting project to do, and had a very acoustic feel to it
,🤙🔧🔧🤙
Dave, I love your channel! I've been a musician and done a ton of recordings in a live situation, mostly Classical and jazz. Was in charge of recording a Symphony Orchestra at concerts for Public Radio broadcast. Did 15 years with a great hall and great mics. After getting an acceptable recording with a singe point stereo AKG 422, I too thought how can we improve the recording experience? after adding spot mics, different stereo pairs and a whole lot of trial and error, We took the three spaced omni small condenser mic approach and the right to left did sound fairly realistic. The hall ambience and reflections was another matter. I'd setup at a rehearsal with an empty hall and it sounded just great, you could hear the hall and it did send you there if you had headphones or a decent speaker listening environment. As soon as the hall filled with the audience, no hall ambience except a bit of people rustling around. Defeated! I ended up getting an early Klark-Technik digital reverb to put some semblance of space in. Live Jazz has the same issues if you close mic everything and mix down. I was able to record for release a club performance that included David "Fathead" Newman where the club and musicians insisted that we record with two spaced mics, about 10 feet away from the stage. Cool until I heard the drums overwhelming the piano and couldn't do anything about it! New designs in speaker systems and computer cancellation of our home reflections and replacing them with the original ambience is a possible move forward. However, we do tend to really like the clarity of mixing down close mic'd sources so we get a "better than being there" experience. No right and wrong as you say, just food for thought.
Interesting and cool
Real stereo is so rarely heard in amplified sound I’m not sure most would even recognize it. I have a Calrec Soundfield MkIV microphone that drops jaws every time I record with it, but it is only fully effective with symphony or ensemble. It is intoxicating to play back those recordings. What is particularly exciting is that a spaced stereo pair of monitors totally loses the discrete problem, making a beautiful stereo soundfield. Instruments have a 3D place in space, on speakers OR phones. I have produced a number of classical recordings with only the Calrec, hearing chuckling from the band… until playback time. I love that thing.
I love this topic. Been thinking about different ways to implement this. Smaller environments seem like an easier task. Sitting in a small venue listening to a bluegrass band with no amplification is a great experience. You get to experience the room and the music together. Making each instrument a bit louder for a larger venue having all the sound emanate from near that instrument would be fine for the audience, but would cause issues on the stage as it gets louder. I'm picturing in my mind a horizontal line of speakers across the front of the stage and panning each instrument to a different location in that array. Instruments stage left would be panned left, then follow the instruments across the stage. Multiple subs could be similarly panned. It would take a lot of equipment to do it, but a cool thought.
With In Ear Monitors, I think it would be somehow possible to electronically simulate Binaural audio. Record each instrument, and make that sound emanate from an imaginary point on the stage. Boss Wazza-Air Headphone amp comes to mind.
Awesome, love the pushing of thoughts and ideas!
This is pretty much what I've been trying to achieve in a live music listening room (meaning the audience is expected to listen, no talking) I've recently opened. Through experimentation I've landed on a different solution that works shockingly well!
Long story short, I'm hanging splayed main speakers front and center over the stage with subs directly under. Everything is run in mono. Then I'm delaying the whole PA signal the equivalent of about 15-18ft (the furthest distance an instrument is likely to ever be placed behind the PA speakers). This allows the listener to hear the actual source just before the amplified version of it. Since our 3D auditory image of the world is mostly constructed from the timing cues of a sound hitting one ear before the other, hearing the original sound source before the amplified version leaves the impression that all the sound is coming from the original source!
Turning the delay on and off is an impressive experience, especially when you close your eyes. You can "feel" each sound move from the PA to its instrument! Even the lead singers voice seems to drop from the speakers directly above down to his/her mouth.
It works so well with acoustic instruments! I would definitely try it on bluegrass!
That's cool bringing the focus back to the original sources
My new favorite channel 😎👍
Awesome and hey hey AP Studio!!
Love the thoughts man!
⚡👍⚡
incredibly insightful, love how you always think in terms of the simple fundamentals. Whats really interesting me are the implications for record mixing and recording - especially when recording multiple point sources in an 'imperfect' space. Thanks for the thought provoking content, Dave
Awesome and thank you!! ⚡
I really enjoyed how you wrapped up the video. Just got here by youtube algoritms. Brilliant
👍🤙👍
I went to an electronics show in the late 1990s where I was fooled by sound. Was waling down the hallway, and a room was open and I heard a grand piano in a room they were serving refreshments. I went into the room and turned left and saw the grand piano with the lid up, but nobody was seated at the piano. Cool I thought a player grand piano. Never saw one so I went over to investigate the player piano. Upon approaching, I discovered it was not a player piano, but a Yamaha grand piano. On the floor next to the piano were two 3 way accoustic suspension speakers. Asking about the recording, the piano was recorded with 2 microphones the night before with no compression, eq, or mixing. It had me completely fooled until I was about 15 feet from the piano and saw the speakers on the carpet. Very impressive and very real. It was a digital recording with good equipment. The speakers were less than 2 feet from each side of the piano on the floor with no stands. Still remember that 25 years later. It is the one time a recording completely fooled me.
Early stereo recordings were often mixed hard left and hard right. Listen to some vintage Beatles and other recordings of the same time.
When stereo television came out, the studios had a very difficult time with using conventional microphones and the result was comb filtering from the phase delays in the stereo recording and the close spaced speakers in a television set. Studios then moved to mono mixes and X/Y stereo microphones so the sound was phase aligned when a stereo mic is used for one point source. This is why in audio production, each performer is picked up with a single mic, not a pair of mics. The phase cancellations are brutal. It was fun watching the TV studios learn that in early stereo television. Sound engineers knew long ago to not place a pair of mics for a single performer unless the recording is strictly for binural headphone use.
I love this! And this is what I want to strive for
this is a great conversation
👍🤙👍
Once my band played as the last one on some festival - raining whole day, getting worse, people leaving. Huge stage, PA, lost time with soundcheck = loosing more people. We decided to get people under cover of stage roof and divide it between a band and audience. Drums dry, bass from amp, guitar from amp, choir dry, 2 violins and 2 vocals slightly amplified with mic directly into RCF ART310A. It was STELLAR. Even if something was quieter than it should be sometimes, you could still hear every single note from every particular instrument and locate it exactly.
Awesome, that is cool. Turning a movie into an interactive play
Sos groso Dave, tus conceptos son interesantísimos. Gracias!
Muchos gracias y Buenos Brian!
Great demonstration and yes super though provoking. I think the visual aid really helps us begin to think about what questions should be being asked. Well done! :)
👍🤙👍
You could mic up each performer individually and time delay each source within the dsp so as to minimize wavefront scattering for most listeners. The recorded performance would also be more accurate. Love the frequency sweeps at the end!
i've always dedicated group outputs on large format mixers to separate submixes for this exact purpose, either for a full surround environment or for a L1 L2 C1 C2 R1 R2 setup. It's fun to always experiment with equipment and sound in general, it seems people just get hung up on certain standards and think it applies everywhere.
🤙👍🤙
Digging that PE product placement!
I love this concept.. placing a Danley Sound Labs Jericho Horn J1-94 in front of each musician on stage, and mix each instrument on it's own matrix.
i like where you are going with this..
🤣
thanks for your videos, sir
Interesting idea.
One interesting thing I found out when consulting on the EAW anya system was that it is practically impossible to make two things sound the same if they have different dispersion charictaistics.
We were voicing the Anya rig and I wanted to compare to the MicroWedge which I designed and EAW builds and sells.
Anyway, we kept testing and comparing and matching the EQ between Anya and MicroWedge and could not get them to sound similar.
Anya has a 70 to 90 ish degree horiz dispersion and controllable vertical dispersion and the MicroWedge has about an 80 degree conical dispersion.
It dawned on me the match the vertical of the Anya to around 80 degrees and wow. Once the dispersions we're matched, it them became possible to EQ the two vastly disparate designs to sound similar.
In my opinion, this is why horn loaded systems are greatly challenged in sound like the original sources and why studio monitors and home hifi are not horn loaded
Not to say horn loading is not useful, but horn loading is not the optimum choice if sonic realism compared to the original source is desired. Unless the original source is also horn loaded or has similar dispersion
Sounds like what you're working towards is the Wall of Sound that the Greatful Dead had built in the 1970s. The speaker cabs behind the band were localized to align with the instruments on stage. Curious what the Rat take on the Wall of Sound is. They also had a really novel mic technique that exaggerated the proximity effect to isolate sources and reduce feedback. This also makes me think of surround sound systems in theaters. You mentioned them, but one thing to note is that as humans we're really good at placing where a sound is coming from. In a theater the center channel of the surround has 90% of the dialouge, stuff recorded on location. This channel lives behind the screen that's actually acoustically transparent. This draws the viewers eye into the image, where in theaters with stereo systems it can be distracting depending on seating position because of phase change. The same things can apply to PA systems, it is something to consider.
Hmm, quite familiar with the wall of sound in fact I even deployed a system in that configuration back in the 80s when I was on Black flag tour.
Obviously putting the PA behind the band is a bad idea and putting the PA farther away from the audience did not sound good
Yes these ideas of separation are good and I'm looking at trying to take this to newer and better levels.
I did a tour of arenas and stadiums worldwide where I deployed multiple Soundsystem side by side and was able to put different instruments into different PAs which worked really well
And on huge scales like that the limitations are more pronounced.
But what I'm getting at is building three-dimensional speakers capable of recreating true Sonic realism where you can walk around behind a speaker and have a hard time telling that it's not an actual human playing an instrument
Oh no it's another video on multiple PA speakers & feeds. After the last few videos I started pondering this some more and one day I realized.......... 5.1 & 6.1 surround sound audio does exactly this different, sounds are sent to different speakers a different volumes to produce the feeling of sound moving around in space. And to think this all started with somebody going to the theater and being annoyed that his movie didn't sound the way he expected it to during editing because of a mono speaker system in the theater.
Well touché you beat me to commenting. Awesome analogy. I think I thought of surroundsound the next day after watching and commenting.
Hmmm, if you only made it to surround sound thinking, you stopped too early
My opinion and this video is actually about why surround sound, Atmos, and all the other configurations available are flawed
Surround sound is like mounting a bunch of showerheads on the walls and maybe even ceiling. And then trying to recreate the experience of being in a field walking through sprinklers.
Sound sources like instruments are more like a campfire or a sprinkler radiating energy outward
Creating a room full of showerheads to recreate a sprinkler field or using central heating to recreate a campfire is using directional energy shooting inward.
This is the reason the recreations fail.
Hello,
First I want to apologize, you are correct, my comments sound like "calling names or insults" I am sorry that was not my intention, does not do anybody any good in doing that, I just get "wound up" when I see "questionable" and simple explanations for topics that in fact are very complex.
Stereo concept, "flawed" or not, emotional or not, preferred or not, best solution or not,.....it is not the topic.
Stereo concept is "THE TASK" .......since 1930 when stereo was invented especially now in modern days ALL music and ALL the artists create in in stereo.
That is recorded on a CD or when you mix it in live performances, with the pan button you place all instruments on the stereo stage and you create the stereo image of the artists being on the stage. Stereo is the industry standard that we have to deal with, like it or not this is the task , the reality.
The sound engineer's TASK is to reproduce what artist created for a larger audience,......Unfortunately that is impossible to do today for more that 10 or 20% of the audience.
I will make you a statement that I want you to take some time and think about it.......
There is NO sound system available today that can successfully do what they were designed to do, TO PLAY MUSIC.
Line arrays , point sources,....can make a lot of noise, can make a lot of sound, but NONE OF THEM CAN PLAY MUSIC.....
Let me explain:
As I mentioned ALL music today is created in stereo, with all sound sources placed on the stereo stage at a precise location. the only way to correctly experience what artist created is using headphones, or at a live event to be reasonably equal distance between L and R speaker stacks in the middle of the venue (this area is not always available because the fenced on security and cable runs to the stage). the rest of the crowd, about 80% of them do not even hear mono ( that is a summation of both channels) they hear one channel only,...that is half of the music, half of what the artist created.
Even if they hear "a smear of the other speaker stack" the intensity of the sound and the late time arrival destroy all the stereo image.
80% OF THE PEOPLE DO NOT HEAR THE MUSIC as it was created by the artist.
What you mix at the FOH location is valid only for customers in front and behind you,.....20 ft left or right they hear something else, nobody knows what.
Stereo image is where the beauty of the music is, there where the magic is, the music comes from the stage, the music comes from the air,.....not the speakers. As I mention the first job of the sound engineer is to make the speaker disappear.
I am working on a solution for this, for years,....and I found it,..... I made small scale tests and it sounds awesome, you can be way outside of the left and right speakers, extreme left or extreme right and you still get the perfect, balanced true and correct stereo image,....it is incredible, it does work perfect, just like having headphones for EVERYBODY at the event.
One has to start not with the speakers or their placement, one has to start with understanding how humans locate the source of the sound. The brain has multiple sensory information to accomplish this, with only two ears we can locate the source of the sound within 2 degrees accuracy in 360 deg field BOTH HORIZONTAL AND VERTICAL PLANES. human ear is an extremely fine instrument.
Most important is to know how does the brain PRIORITIZE the multiple sources of information. You can manipulate this for the brain to "think" is in the middle of the stereo image,.....even when it is not.
Next year when I retire I plan to build a full scale sound system using this concept and organize small EDM music events where the customers will hear for the first time,....the music, the whole music,.....ALL of them will hear the magic. The sound system is going to be ALL analog ALL horn loaded with the correct calculated horns to the 1/4 wave length, even the subs, not there make believe or horn want to be.
For 40 years I collected a vast amount of analog processors, I have a room full of them.
Used responsibly they can drastically improve to the quality of the sound, dynamics, full spectrum, presence, vividness, transients, and most of all the stereo image,....this are all analog (real sound) not computer plug inns. I have multiple copies of the only analog stereo image "computer" ever made. It allows you to "decompose" the stereo image components, and put them back together any way you want to enlarge the stereo stage,.....it works wonderful, it sounds awesome. Using these processors transforms the dull lifeless, compressed, limited music on CD to a better than life performance.
Trust me they work very well,......no disrespect,.... I don't think you were even born when I started in audio.
I am sorry we started on a bad foot, we have the same life long passion, I would have liked for us maybe to start with a nice cup of coffee sharing experiences.
Again, apologies for the inappropriate, colorful remarks.
Andy Munteanu .
Cool stuff Andy and interested to as always to see cool ideas and solutions.
I will make some vids on a couple of relatively simple ways to improve some parts of sound reproduction.
For me, the combining of lots of sound (energy) sources that radiate from various physical locations into a few speakers that radiate all those separate sources from a few locations is one deficiency.
Another deficiency is that speakers tend to be directional or they radiate similar or the same sound in wider or Omni directions. Actual instruments and most sound sources wwe are reproducing tend to radiate differing sounds in differing directions. Even a Marshall cab has a lot of rear radiating murky sound, cymbals and drums radiate with completely different dispersion patterns than the loud speakers used to reproduce them
This is another major deficiency in sound reproduction
Those two deficiencies combined result, I believe, in stereo systems as we now know them, in being severely hobbled in their ability to create realistic reproductions.
I have had a 222-seat theater at my disposal in Fort Lauderdale for some 35 years. It was a church way back but is now fully godless and it’s a magnificent sounding room. Very steep seating, heavy velour curtains over stained glass and exposed concrete. Since I could do what a wanted, I installed a coincident pair above the stage angled out about 60 degrees, on its own stereo amp. I have really enjoyed boldly mixing stereo in that room, sending maybe half the sound, or more?, to that pair. I can’t think of any reason big setups should not do this. It’s highly room dependent of course, but quite an ear-opener in a nicely proportioned room.
👍⚡👍
I would love to talk about concepts for a mono or X-number of speaker system (doesn't have to be two: Left / Right) that can enhance a rock band in small and medium venues, mostly without venue PA. You're an artist and a genius. Van Gogh, Michaelangelo, and Dave Rat.
I have thought about, but never figured out how to approach the musicians, having control all instruments from the console, by inserting some type of control between the guitar and amp, for example. Maybe just a rack of EQs with level control.
Sort of turning the live venue into a recording studio, with the ‘producer’ in control of each sound source.
If only record companies released multitrack versions of songs/albums! You could have an assortment of speakers, one for each instrument so it may just sound more "life-like"... who says 5.1 or 7.2 or whatever has to be surround? Make it one speaker per instrument or at least groups of instruments, set up multiple speakers in front of you, not around you :) anyway, great content, criminally underrated what you're doing here, Dave, i'm learning a lot of interesting concepts from your videos, thanks!
Yes! You get it!!
NICE, THANK YOU. 👍🏽
🤙👍🤙
PLEASE DON'T STOP SHARING YOUR KNOWLEDGE!!
At university in the 80's I remember hearing a Neumann dummy head binaural mic in headphones and the positioning of sound in space was amazing. Needs headphones to work. Seeing someone walk up to me with the mic head turned around and hearing their footsteps coming from behind was truly freaky!
Have been playing around with the Dolby Atmos in Logic and it seems no where near the old tech... It kinda works if you think about it wanting to work! Not sure why. this should be run of the mill stuff like MS is for stereo widening on the recording side!?!?
Making music correct in a large stadium environment is still a goal worth pursuing.... bringing the performers closer to the people and the people closer to the performers.
Thanks
Thank you Andrew⚡⚡
I mostly gig solo guitar & vocal shows in bars and pubs, often needing only one speaker for adequate coverage. To check for an improvement in clarity/fidelity it would be easy to put up two powered speakers side by side and pan vocals L to one speaker and guitar R to the other speaker.
May be fun to try
Totally. Rock concerts from the 60s were incredible. Typically, the PA was for vocals and the musicians played there amps through amps that they controlled and in performance amps weren't mic'd up. I saw Jimi Hendrix playing through Sun amps that were not mic'd and he sang through the house mic PA. Very simple and needless to say sounded great. Now days all of the sound is funneled into a mixer that spits out right and left mains. With this set up the best you can hope for is a sound that approaches the quality of listening on a high wattage stereo system. However, Jimi Hendrix sounded way better any record and it was live and not funneled through a big PA.
Very cool and a big inspiration for this adventure is the many years I have spent seeing bands in rehearsal spaces getting ready for concerts and tours.
The sound of a great band rehearsing with just their apps in a vocal PA is amazing and fun and cool and going to small clubs can be an awesome experience.
That is the sound layout that would be so fun to recreate in the home and other environments
It's interesting how I've intuitively thought this and tried a bit before being told and taught the correct normal way.
👍🤙👍
Always a pleasure to watch your videos. I remember experimenting with lots of little speakers and sources in a room and thinking there will be a way someday to build it up to scale for large events. That being said, have you heard d&b's Soundscape? Granted, I might be biased since I mostly use their gear but I must say it's a game changer for me and certainly a good step in the right direction.
D&B soundscape, Dolby Atmos, and L acoustics L-Isa are interesting ways to smear sound sources around between various speakers to try and create the illusion that the sound sources are located in various horizontal and vertical or rear or overhead locations.
This is all fun and useful and has applications.
What I'm referring to is that as long as sound systems are designed to be a bunch of shower heads shooting energy at the audience they will never accurately sound like many of the sound sources they are trying to recreate.
Actual sound sources are more like sprinkler heads in a field shooting sound in various directions where you can walk between them closer and farther. Trying to recreate this with shower heads blasting in the audience direction may be useful for practical but will not create audio that sounds like the original
@@DaveRat As always there is always a compromise. Yes, I agree with the concept you put out there and hope better solutions will emerge. On the other side I think the limitations of PA setups over the years might have conditioned the general public to expect a wall of noise to be blasted at them from a stacked or a flown bunch of cabinets regardless of what the instruments actually sound like in person. It amazes me how many people confront me for not taking part in what I consider to be this generation's loudness war. We moved from louder on CD's to now louder live mixes. I constantly see this babysitting at festivals where guest acts try to push everything to an eye watering limit. Yes, the most truthfull sound you get in a small room where nothing is really put through those showerheads but to my annoyance, people started asking me for double bass drum mics on a jazz gig in a small pub. Anyways, great food for thought and thanks again for all your videos. 😃
👍🤙👍
@@PadreAG I hate the waste of seeing great musicians playing and the PA is producing more energy than the room can physically hold with any clarity at all, no matter how "good" the sound system is. I also get sick of hearing nothing but kick drum. Thank God for the growing trend of listening rooms!
Too loud and too much kick are not optimum and yet just like everything, opinions of "too much" is a vast landscape
hi Dave,
very exciting and good thought !
i wish i could place almost invisible speakers (with high efficiency) directly above the individual musicians.. (in a small venue)
cheers from berlin
Cool co Curtis
I hang splayed mains directly over center and delay the whole signal by the equivalent distance of the mains to the rear most instrument (usually the drum kit). In my setup that's usually 3-4 meters. The PA becomes virtually invisible! I describe this further in my response to Dave above. The effect is dramatic! The impression it leaves is that all of the amplified sound appears to be coming from the original source!
When you think about it, It makes sense but...... Live sound recording is an art and there is a science to speaker design and speaker placement. A vast majority of people place speakers in 1 of 2 places, where it looks or fits best or where there wife will allow them too. When executed correctly, speakers should disappear within the room. Sitting in the sweet spot with your eyes closed for about 60 seconds, then point to where the sound is originating from. If you open your eyes and see that you are pointing at the speakers, then they are not positioned correctly.
If they are positioned correctly, it will create an audible 3D environment which creates the illusion of the space that the music was recorded in.
All systems do not need to be perfect. I like lo-fi background music as well as movie surround sound and a rocking concert setup.
Also, the methods we now use for sound reinforcement and coverage does rely on a sweet spot.
Which highlights the flaw to the coverage method.
Someone playing accoustic guitar in a restaurant sounds real in every spot in the room, not just almost sort of real if you sit right here and don't move your head too much.
Im mostly mixing in a home recording environment so im not sure exactly how that applies, BUT I will say I can resonated deeply (no pun intended) with the main philosophy behind this. Shitty band rehearsal garage sessions where everything is cranked to compete with the drum kit is some of the most meaningful sonic experiences I have ever had, I can understand now that that is all the individual point sources bouncing and livening that environment, and every band member would have had a completely different 'mix' depending where they were standing in that room. Small venue concerts with the guitar / bass and drum kit all present really point source volume in real space. A very special experience indeed.
A group of about 1000 people singing 'praise God all creature here below' hymn in harmony at a bible college, being in the audience of these people and hearing literally 1000 different points sources....
Yeah it makes a lot of sense what you are saying NOW SHOW ME HOW TO REPLICATE lol
I will work on some videos with simple demos
Interesting way to look at it. I venture to the other end of the spectrum for my personal listening experience. To me, stereo sounds better than "live sound". Live sound is too loud, too high frequency or bass heavy, has too much reverb, there's people talking and making noise etc...A good home speaker set sounds intimate and very "acoustic" and organic. Omni directional speakers have more of this enclosed listening quality. The good home systems provide offers more clarity and precision. I like the idea of "multi-track" audio for multi point speaker systems as well though. Really a difference in the experience of the sound to have all this stuff reflecting in different ways with different setups. I was blown away when I heard the bose micros in my house. They seemed to "open" the sound up with a feeling that you could grab the instrument. It seemed very rich in volume but the sound did not actually travel outside the house which is good. With stereo, depending on how far apart your speakers are you get 5 strong points (far left, mid left, center, mid right and far right), those points then reflect obviously in interesting ways creating more focal trajectory. But again it's just a different experience. One thing is for damn sure we got to get away from the phone mixing based production. I came up with an idea called stereo cell, that basically is the concept of attaching very small but good speakers to a cell phone. In this way it can still fit in your pocket like a cell but would provide much better sound with the latest speaker developments. The new gen wants super exaggerated kits which is a whole nother issue ha...They sort of bake all this directional stuff into very basic arrangements (less virtuoso musicality but the listener can "feel" the vibe because the kick is 20db too loud). lol.
Hmmm, comparing processed home hifi and recordings to live where everything is pumped through big speakers in a more raw form at higher level. Yeah, stereo is less intrusive.
But 2hat about comparing both live PA system sound and home hifi sound to say, someone playing an accounting guitar, a stand up bass and a percussionist?
My take is that both live pa and home hifi and surround sound and all the other formats fail at reproducing sound even close to the original due to flaws in the formats of reproduction.
Your videos on that topic and how you came to use a double hung PA and seperate the sources in the wedges have definitely triggered something in my brain and I'd like to share my thoughts with you...
I've been following the adventures of @PresentDayProduction moving towards Dolby Atmos mixing and having the possibility to assign each source to a single speaker recently. I've found the technology behind this really interesting.
This makes me thinking a lot about about the general problematic of live sound reinforcement and I wonder if Atmos would be something that could be usable (in the future) in a live environment.
It seems to provide better clarity and a better image when mixed for an immersive experience and then processed down to a stereo setup than a classic stereo mix.
Of course, Atmos is designed for a single optimal listening position and latency would definitely be an issue for live use at this point in time, but I wonder if that kind of technology used on a double hung PA could be a valid solution to make it sound more natural.
This is just theoretical thinking and Atmos is too expensive for the average venue anyway, but maybe there's a way to use the virtual speakers concept with the equipment we use live today... Just thinking out loud
Sound sources radiate sound outward towards the listers and the walls
Atmos is designed to project sound inward from the walls.
Like tryin to recreate the feeling of sitting around a campfire by using central heating and adding more vents on the walls
Atmos is good for creating secondary sounds coming from external directions but does not address the accuracy and realism of primary sources that would be located in and amongst the listeners.
In terms of hifi audio, you could check the Learprint system by Alain Français, he reproduces the sound of an orchestra by replacing the musician with a recording of his instrument and a unique speaker only reproducing his recording. You end up with a pretty big amount of speakers but the illusion works
I have looked into that and tried smaller setups with excellent results
totally agreed on this video !
⚡🤙⚡
Another thought….. maybe what you are heading toward is using a monitor mixer for the FOH so you can send a lot of different mixes to an array of widely spread speakers. Probably work better in smaller venues rather than arenas but I think it will work better than a stereo mix
I think there are a near 8nf8nitenanountvof application dependant solutions and advanced to be made.
And trying to continually push stereo to higher and higher levels of perfection is not one of them
This is how my electronic music studio is set up. It sounds amazing. I actually record it with a zyllia 3d microphone
That's cool
I’d venture to guess that even choosing items from the shelf at the grocery store , and how to place them into the cart is just as thought provoking for Dave. Lol …. Just kidding
This was very deep AND very useful.
I can think of three sound signals I’d like to transduce from different speakers than the usual mains.
Thanks Dave!!!!
🤙🔧🤙
It all about the flowers of energy man! (Great band name BTW!)
Audio, Zen, Guru, love it
🤙🔧🤙
Wow another shirt IDEA...OUT OF THE BOX!Kidding aside...thank you for making us think outside the box...cant wait to read negative comments from people inside the box...this sure hit them hard
Fun!!
@Dave, I really appreciate your push to think about this from a different theoretical perspective. Could you do (or have you already done?) a video suggesting practical experiments to explore these ideas using sound equipment typically already found in small-to-mid-size venues? I think a lot of us would love to hear your thoughts on how we might do that.
Hmmm, I will continue to vid more. Not sure how far u have dived into the sound testing and listening playlist and the vids on mixing. But yes, will continue to expand
@@DaveRat I appreciate your kindness in being polite enough not say, "Watch the rest of my videos, dummy!" Ha ha. But I'm working through your channel slowly as I have time. These topics take time to digest and ponder. Much respect, sir!
Thank you and great to meet ya Luke!
Interesting 😊. ❤ Now you have me thinking about a speaker to represent each instrument with the correct bandwidth positioned to recreate the sound for each instrument as it was originally recorded, as closely as possible .
You know when we have a surround sound processor and they do a 7.1 and 9.111 point 1 and then they do 11.2.2 we really need A 256. At the very least we need A128 channel receiver or to isolate each instrument and each sound to heaven discreet output.
It's like when guys install audio and they go with one large wolfer 1 mid range and 1 tweeter. It's been 3 way for decades. But I say like with nanotechnology and other forms of reference you want to increase the resolution you have to increase the points of output. But we're still using nuts and bolts so everything I'm saying is far fetched.
But I think like with turbine engines or other forms of Turbo and accumulator and intensification... We do it with machines and other processes of principle in life but we don't do it with audio with motors is motors woofers and drivers. I've always thought that each size of a driver has a purpose and tightness and looseness and benefits for the ranges of frequencies on the octave. I see some guys with a system that has 20 of the same driver I always thought that if you have a fluctuation and you have an extensive cross over network and you overlap frequencies between each device you're gonna have really full tight and loose you're just going to have the reality. A high reference representation.
Love this
Surround sound is backwards. It points everything inward and we need multiple sources with speakers pointed outward
Apart from the live sound maintaining challenge a question in a recording or broadcasting situation would be how to catch and transport the individual original / close up sound sources PLUS information about the 3D position of each individual sound source, transport all of that information and sounds and recalculate a sound perceiving experience at the desired listeners (virtual) position. Part of the process could be a kind of stereo mixing „recipe“ if stereo playback is required, as well as headphone mix „recipe“ or even others, maybe let the listener decide where (virtually) positioned. Crazy enough that unnatural stereo mixing and listening is still standard, but that we have to „phonitor“-ise that mix in to our headphones in order to make that sound , well, OK. Sorry 4 my clumsy English, hope you understand…
It does not need to be that complex. You are over thinking it.
Very interesting analysis. I think point-source speaker were born as a means to an end, but maybe they became an end on themselves. That'd be wrong from an engineering standpoint, if one specific solution becomes the goal and there's no room for any other.
Orchestras in a theatre, for example are the perfect example of a "real" listening experience, with literally one point-source for every single instrument. Thanks for the video!
The idea of a coherent point source happened at a time of a single microphone was the source of pickup for a live performance recording. 2 channel happened with 2/3 microphone pickup for live performance recordings. Classic loudspeaker theories developed due to this simple recording techniques.
Multi track recordings of non acoustic performances challenges the rules of classical loudspeaker design. So yeah I guess this needs a new perspective. I believe three DSP controlled dodecahedron loudspeakers in the front is an alternative approach.
👍🤙👍 expanding beyond the horse and buggy approach. Gas engines are the way. Oh wait, electric?
Innovations and resistance to innovations is the way forward
Dave, this topic is great. Is really thinking out side of the box. Literally. But, thinking outside of the box is directly proportional to increasing costs. How can you achieve power over distance, without having enough pa ? Are we talking about a hard evolution of sound that should implemente development not only for speakers , but consoles also ? How much will it cost and how will that affect an overall budget or even an artist fee ? Is crazy to think that thinking out of the box eventually comes to money ,,,, or not ?? You yourself are a vendor , and if I come as a cliente looking for this experiences for my audience, how will it affect on my budget ?
I guess the answer to the question of why we don't do this is budget and practicality. The cost, setup time and the complexity of mixing with a system comprising multiple speakers or arrays all over the place would be prohibitive in most scenarios. It's complex enough when you have left/right hangs, side hangs, centre hangs, delay hangs and time aligned sub arrays just to get even coverage in a room. I suppose the best we'll get is double hangs, one for vocals and one for instruments, or maybe double hangs plus a centre cluster, or putting vocals in mono centre and instruments left and right, but if you're trying to cover an arena, then you'd need an inordinate number of additional hangs. It's a dream that sadly I don't know if many people would be able to achieve. Curious to know how you're solving this on recent or upcoming Chili Peppers tours? I know you like to use multiple mics and pan them differently, but have you ever gone beyond that?
Well, I stopped touring in 2017 so no current mixing for me.
Another way of looking at this would be to ask yourself, what if a new level of sound clarity and realism could be achieved? Is it possible the sound systems would then get financial budgeting on tour closer to what lights and video make?
Do we not perform because the money is not there or is the money not there because we fail to be amazing enough?
I don't have the answers and also asking the questions and pointing out the fundemental flaws to the current approach, perhaps could inspire some progress
nice thank you
👍🤙👍
Spacial Audio is designed for what you are talking about. It's similar to surround in movies. I think we'll see music evolve to be less stereo located in the coming years. Of course you also have to mix for very small boom box audio sources in mono even, which is a bit problematic, but that might have to come down to source selection. Since so many people get music from places like Apple Music and Spotify, that might just end up a preference selection. of course you'll have to normalize consumer purchases of multi speaker setups and hope that's affordable while actually sounding good.
Point is, the technology for creating that in the studio already exists. For live it might be a moot point in large arenas though since that would only make sense for people within a distance to the source. Unless you actually turned the whole stadium into a surround system. But then you'd lose source focus in a different way. Being close to the stage would a subpar experience compared to being out further.
So many tradeoffs!
Well what I seek are sound sources that radiate sound outwards in various directions. Imagine an acoustic guitar player, now walk around that person while they play. It's brighter in front and duller behind, but not just EQ, behind you hear the resonant body more and in front you hear more strings and strum.
A speaker you could drop into a restaurant and people as they walk by would do a double take as it sound near exactly as if a real person is sitting there playing.
I don't know of a system that does that currently but have built one and working on version 2.
These are ideas I've pondered a lot, myself. I don't think stereo ruins anything. We need a way of representing a soundstage while maximizing convenience for the producer and the listener. Two channels are pretty easy to handle from production to consumption. Adding more channels necessarily complicates things. Different applications call for different configurations and that's fine. I think it could be perfectly reasonable to have a single sound per driver or enclosure, under the right circumstances. For most applications we need just enough full-range channels to support the illusion of a soundstage and two is the magic number.
As far as recording and reproducing a complex audio environment, I think that recorded and reproduced sound can only ever be a simulacrum of the original sound occurring in space. No matter how natural a recording sounds it is always an abstraction of reality and that's just how it is. That said, not all recordings strive to reproduce natural sounds in a natural environment. These days days we can create sounds with have no origin outside of a computer; they're virtual through and through, so maybe, for sounds like that, the system you're listening on is the right one no matter what.
I love many types of systems. Mono speakers in various rooms for background music at the house, stereo for stereo recordings, surround for movies and so on.
Also, none of those systems are capable of recreating the way sound sources generate sound by radiating sound outwards in many directions outwards, because all those systems are based on pointing sound inwards
@@DaveRat Right, that's what I meant when I said it's a simulacrum and an illusion and an abstraction; There's no way to reproduce a real-world sound source with a speaker.
Hmmm, I believe there is at least ways to get close
@@DaveRat no way to * perfectly * reproduce. :)
Perhaps but I believe there are approaches that will reach higher levels of realism. I will continue to expand on this in future vids
Thanks Dave! Always keeping us thinking. Innovation is lubed by weird or oddball, questions, thoughts, and ponderings.
And the funny part is for me, this all seems obvious and fundemental
A system that is capable of taking individual tracks from a mix and distributing them to different speakers would be cool. It would be like an Atmos mix, but all the speakers are in the front of the room. I could get behind that! I don't notice any benefit from surround sound, so I'd just as soon put all the speakers in the front of the room.
Agreed
Immersive audio. It’s on the move!
🤙
David Rat; targeting a normal stereo hifi, i’d love your comments to using your mixing concept in a studio environment. Hard panning 2 source mic’s, etc.
I cover a lot of this in other videos I've done and even more so on the member side
Hi Dave,
I do get your point in that sound from two points never sounds the same as is does from stage. The same reason why I don't believe in surround sound for music. (Film is a whole other domain.)
I do have some issues with the comparison that a "sub here, a mid there and a tweeter over here" might be more comparable with the sound as it comes from stage as it produces fase-diferentials.
The sound from the stage are frome different locations but all contain a full range of frequencies.
It would be nice to amplify every instrument by his own speaker. The problem we would run into is that te visitor standing on the right of the stage needs a different speakerplasement to match it his or her's view of the stage.
Thank you for you video's.
God bless,
René Leunk, the Netherlands.
I have more videos planned and will dive into this further with examples and demos that hopefully will expand and clarify some of these ideas
Thank you for your response. Looking forward to the video's!
👍🤙👍
It is interesting to see this perspective. I don't think an instrument which spans multiple frequency drivers should necessarily come from different places because that isn't all that real IMO. However I did just recently see a video from someone with the opinion that sending just the instruments of a certain frequency range to the subs was a bad idea. They had a fair case but I don't know that it's all that bad. That is the simplest form of what you are talking about I think I've seen. I have wondered if at least for vocals if it wouldn't be better to have a center array. That might be cool to try but the bigger the place the harder all that is and given how much concert tickets cost these days if you fail to cover some part of a giant space with full range people don't like it.
Covering the entire audience is extremely important.
And yes, there are people, well known engineers that have trouble with separate sub signals
And they believe that every mic, even the high hat and vocals must be able to get to the subs and then they EQ and high pass to try and not send those signals to the subs.
Or, you could just send the signals to the subs that actually need subs, which to me makes more sense and sounds better.
This is very interesting. I think playback of each instrument through a dedicated loudspeaker - maybe even one whose radiation pattern approximates that of the actual instrument - would create an extremely enjoyable playback experience. For instance, maybe narrow pattern for the horns, medium pattern for the guitars and vocals, and omnidirectional for percussion. Unfortunately I think this would call for a custom multichannel recording, in addition to a rather elaborate and recording-dependent playback multichannel loudspeaker configuration. I think Dave's idea is definitely a better solution, but I'm not sure how it would enter the marketplace... ??
My background is more on the two-channel playback side, where we're limited to those everything-in-a-cardboard-Dayton-Audio-carton stereo recordings. Where the playback room's acoustic signature (reflection pattern) dominates spatial perception, under good conditions we may have a "they are here" presentation, with a plausible illusion (eyes closed) of the performers being in the room. Imo a single dedicated speaker per instrument would create a MUCH more convincing "they are here" illusion, should that approach ever show up on the market.
There is another kind of presentation that hardcore two-channel guys sometimes pursue, which might be called "you are there", wherein the acoustic signature of the recording venue (whether real or engineered or both) dominates spatial perception, such that you close your eyes and it sounds (or "feels") like you are in the acoustic space on the recording. Imo a good "you are there" presentation is, for now, probably as good as it gets (spatially) for two-channel. I'm not sure how to optimize Dave's idea for a "you are there" presentation, but his idea probably has greater potential in that area than two-channel does.
Good stuff and fun. Mono and stereo and surround are all awesome and there is more fun to be had with pushing things further
For instance, one sound i specially wouldn't mix with others is metal guitars, because it's a rather unique sound it usually doesn't sound very well on flat systems.
If i could build a sound system,I would run at least a separate PA made of guitars cabinets just for the guitars.
Agreed that hard driving guitar never sounds quite right on full range speakers
Hahahaha please David make some speakers like that I agree with you !!! Let’s do natural sound it’s better than squashing all of it into one I like it !!!
Deeeffff wall of sound was into something we should explore this route more
You should make a post of open submission designs and the best unconventional design wins or the best 10 and we try them all with different bands like really question this with empirical knowledge and testing it live !!!! This could really be a HUGE turning point in the live sound industry !!!
Will ponder a vid on some speaker setups that offer more realistic audio
Dave, I suggest that you should set up your "dream system", applying all of these thoughts, and have people come over, listen and talk about their impression. That would be an amazing experiment!
Also to comment on your thoughts: I consider that stereo systems work great, but for a single listening position. In this cases having coherence among speakers and a controlled room will definitely be beneficial as the intention is to keep those out of the equation. When there is no single listening position, I think your approach would be better. Thinking about it, this is somewhat what happens on very small events, right? Guitars, keys and basses sound through their own amps, drums sound by themselves and vocals are on the PA. However, most of the time they are not carefully mixed...
I will share more vids and ideas over time on ways to make this work
Love what you're trying to achieve here! I'm curious about your thoughts on delayed PAs and also a compromise between what you're doing here and a delayed PA.
So, after fighting horrid room acoustics for years as a live sound engineering, I've recently opened a live music listening room large enough to comfortably hold 100 standing. The room has fortunate dimensions for acoustics and then with further treatment really sounds fantastic. The whole time I'm creating this I'm hoping to keep volume levels just at or above the non-amplified drum kit level.
After experimenting w speakers in more traditional 2.1 arrangements I decided to suspend the 2 splayed mains over the center of the stage (in mono) and found it expanded the sweet spot dramatically!
Then I tried delaying the entire PA the equivalent of 15ft over the 20ft deep stage. At the lower volumes we can push, the delayed PA becomes shockingly invisible as the original source hits the ear just before the amplified version bringing back a truly realistic image! You can FEEL each vocal and each instrument move from the PA to the source as you ingage the delay. I find myself demonstrating it to musicians and other engineers often.
I'm wondering how well it would work with a delayed 3.1 system for louder venues? This seperates many instruments from each other and the image would remain roughly the same anywhere in the room.
More than I can dive into in a comment response. We cover more in-depth stuff on the member side in zoom chats and such
We do this kind of thing for vocals for live theatre. Works great!
Using independent vocal sources is great and a step in the right direction. I've applied this concept on arena and stadium level concerts as well with excellent results.
My focus now is on the other end of the spectrum which is smaller format and trying to reach higher levels of realism.
If that's successful then looking at ways to scale that
@@Lunatic768 Oh yeah, delayed amplification would work really well, and makes a lot of sense in theater. As I think about it now, I can recall one particular theater that always made me wonder how the actors sounded amplified but yet not amped.
Why do I not hear of this being done in live sound? I assume I'm missing something. Is this done all the time and I'm simply not hanging with the cool kids that are doing it? Is this a luxury from being in a fortunate room that I'm taking for granted or what?
I realize that I'm not pushing levels as high as some but it gets pretty loud and the effect still works, though I imagine it would be reduced at a certain threshold. Actually I guess it would have more to do with the ratio of sound between the original signal and the amplified version.
always found that panning mono sources doesnt make them sound like they are in real places in the sereo field and i figured this was due to there being no timing differences, if there were pan controls in a mixer or daw that introduced a few ms of delay to the weaker side i think that would improve believability
Haas panning is useful
could this be why small basement shows I went to growing up always sound "better" to me and hold a special place in my heart then when I go to big venue shows these days? In the small basement shows nothing is mic'ed up, every source is coming from what is producing the sound the only thing in the PA was the vocals but the you often could still hear the vocals coming from the singers as well.
I think so and like that as well
It seems to me that no matter the efforts we put in making great (or not) sounding boxes (I'm one of them...), we are just creating other and/or new experiences, that did not exist in the first place.
Listening to music through speakers is NOT listening to an instrument, or whatever was supposed to be RE-produced, nature, people, environnement...
Just like taking a photograph is NOT seeing the thing for real.
Yes and the creation of unnatural, interesting and exciting audio is wonderful and fun and awesome
And also if we understand and develop the capability to recreate a sonically realistic sound source, we can add to what we do and also have a reference point.
We don't need to recreate realistic sound but it's important to also know that the methods we currently use to recreate sound is also not capable of it.
Five instruments with five separate individual speakers in one monitor case/box makes sense to me. I've always thought of "stereo" as 3D audio This theory is fantastic. As if the room itself becomes the mixing board. Out doors is a whole different animal.
I think the concept can be pushed farther
the most likely result will be horrible comb filtering. there's nothing impossible about what you say, but the Crossovers required to make something like that sound good would be very expensive.
Interesting perspective. I took six small speakers and recorded an acoustic guitar with six microphones in six different locations and reproducing the six Mikes with the six speakers creates a three-dimensional sound source that you can walk around and sounds realistic and similar to the acoustic guitar being played that I recorded in the first place.
The whole system cost less than $300 plus the cost of the six channel teac recorder
For amps I use these $25 stereo amplifier boards.
So I can say that inexpensively and relatively easily what I described is doable and I will do a video on it at some point
I somehow feel like you are pointing your finger at me 😘
But on this video, I totally agree with you
I have a project where I really want to design a multi channel sound system for a club, but face the problem: When are sound engineers and DJ's going to be ready to output more than LR or LR + Sub? Having dipped my toes in ambisonics mixing, I really love the new dimensions it opens up, but find the applications in "the real world" to be disappointingly limited to conventions.
What do you think we can do to help push the transition to multi-source sound systems?
Great video, as always
I will continue to ponder and present ideas and possible solutions. Touring with the double hung PA design was wonderful and believe more people should give it a go. I will post more vids with ideas
@@DaveRat Have you tried L-ISA or any of the similar systems with a high source-count loudspeaker system?
9h yes, I've been to a personal Atmos demo at Dolby studios, I have seen and heard L-isa before it was even released and deployed for gigs. I work closely with L-Acoustics and have quite a large inventory of their speakers.
All of these systems shoot a bunch of sound inward 8n an attempt to recreate the sound of instruments that shoot sound outwards.

Very interesting. It's the difference between a bare lightbulb in the center of a room and a flashlight in the same center of the room.
Yes with the flashlight sending the same info in one directions and the light bulb sending differing info to the front and diff info to each side and diff info upwards and downwards
@@DaveRat So in a concert, your job is to make the flashlight's beam audibly shine on everyone equally. In nature, the sounds of the crickets come from over there, neighbors dog barks over there, the damn woodpecker driving me nuts over there... What are your thoughts on reproducing that for a show? An image pops to my mind of percussion in the center, with a 360* degree spread outward into crowds and other instruments coming in from single point sources from a ring around the outside of the audience. Bass would probably be with the drums but guitar would be over here and keys coming from over there, vocals from over there... The soundmans job would be to mix by spreading those single points in such a way that sounds best. That seems like an untamable beast but I know very little about it at this point.
Or are you just recognizing the truth about the nature of sound and letting that be your guide in how you mix sound for the Peppers? Very cool, by the way. When I grow up I wanna be a kid like you.
Sorry for the ebook but how else could I have asked that question in only 4 lines of text?
I hope too and will try to do a video on two different perspectives on dealing with the limitations of stereo sound
Felt good to push the like-button - It was 999 likes. Now its 1000. Had to share my seconds of pure joy. I even un-liked it to re-experience it.
I love that and thank you!!!
I wish this guy was my math teacher,maybe I would have been a physicist.This man sure knows how to make a boring subject interesting
You made my day!!
