More About Studio Monitors:
Studio monitors are loudspeakers in speaker enclosures specifically designed for professional audio production applications, such as recording studios, filmmaking, television studios, radio studios and project or home studios, where accurate audio reproduction is crucial. Among audio engineers, the term monitor implies that the speaker is designed to produce relatively flat (linear) phase and frequency responses. In other words, it exhibits minimal emphasis or de-emphasis of particular frequencies, the loudspeaker gives an accurate reproduction of the tonal qualities of the source audio ("uncolored" or "transparent" are synonyms), and there will be no relative phase shift of particular frequencies-meaning no distortion in sound-stage perspective for stereo recordings. Beyond stereo sound-stage requirements, a linear phase response helps impulse response remain true to source without encountering "smearing". An unqualified reference to a monitor often refers to a near-field (compact or close-field) design. This is a speaker small enough to sit on a stand or desk in proximity to the listener, so that most of the sound that the listener hears is coming directly from the speaker, rather than reflecting off of walls and ceilings (and thus picking up coloration and reverberation from the room). Monitor speakers may include more than one type of driver (e.g., a tweeter and a woofer) or, for monitoring low-frequency sounds, such as bass drum, additional subwoofer cabinets may be used.
There are studio monitors designed for mid-field or far-field use as well. These tend to be used in film scoring environments, where simulation of larger sized areas like theaters is important.
Also, studio monitors are made in a more physically robust manner than home hi-fi loudspeakers; whereas home hi-fi loudspeakers often only have to reproduce compressed commercial recordings, studio monitors have to cope with the high volumes and sudden sound bursts that may happen in the studio when playing back unmastered mixes. - Věda a technologie
THANKS FOR MAKING ALL THESE VIDS YOUR KNOWLEDGE IS MUCH APPRECIATED!
Thanks, friend :-) Very informative 3 part series = subscribed!! I thought of doing a build of EXACTLY what you are doing - also using SigmaStudio and building small portable "cube style" monitors and then I found your video after searching = GOLD!
Thanks for the series, now i want to make those too!
loved the series, think you earned a new fan!
Awesome, thank you!
Die Video Reihe ist ja schon etwas älter.
Aber die Lautsprecher sind wirklich sehr gut geworden. Glückwunsch!
Gibt es irgendwo eine Dokumentation der von dir vorgenommenen Einstellungen in Sigma Studio ?
Dankeschön für die Vorstellung der Lautsprecherentwicklung und gegebenenfalls für die Bereitstellung der Einstellungen in Sigma Studio.
Beste Grüße aus Berlin / Deutschland
So I havent seen your videos before and I'm only a minute in and great framing, excellent shots, excellent cuts and spot on cinematography. I'm not expert but I know good work when I see it.
Wow, thanks!
how does it sound? would love to be a video testing it
Hi Gary. Maybe next time you could try REW's in-built EQ tool to automatically find filter parameters which you can then set inside of SigmaStudio?
That was amazing good / love you honest opinion about the sigma studio / I’m still gonna do this small boxes / by any chance do you have dimensions for the wood cuts and did you use any insulation inside the box.. thanks for doing this sir ..
use cinetic feedback (CFB vitesse or current) to minimize phase.
would be nice to get little soundcheck after all. some copyright free music and moving camera mic side to side, how directional sound is.
Love this series! Question about the CX120; their ideal cabinet size is really small (something like 4.3" sides in a cube, I think), do you know the volume of your cabs? And I noticed you didn't use any internal damping in the build, was that related? Cheers, please keep making excellent videos!
Good question!
Great vids gary. How many bands of EQ does that DSP allow per channel. Have you tried the Auto EQ function in REW. I've had pretty good results with the EQ function. It give you a really great baseline to do minor tweeks. Lastly were you using a calibration file for your mic in REW? I absolutely LOVE the cubes you built!!!
Thanks Sam, I really don't know how many bands of eq AD will allow, its a matter of total Dsp available, you can trade more eq bands for other things. I have used the auto eq in REW extensively, it works well. I was using a DBX reference mic this time as I was also using Smaart live and open sound meter off camera. Thanks for watching!
Excellent video! One question that bugs me though - and maybe this is something you are looking to address later - is a measurement in a non-final location useful for more than broad-stroke tuning? Will you end up fine tuning each DSP once these are sitting where they will be used? I'm interested to see how much of a difference in measurement that may lead to, given the little bits of the room around you that are visible in the video.
Hi Aleks! sounds like we need another video, My intent this round was to establish a base line as to the performance of our little cube. Think of it like this, you run down to Guitar center and grab a pair of KRK's bring them home and plop them on your desk and start mixing, we have already exceeded this in that we are a least tuning in the same room. Yes I fully intend to do final tweaking when there on my desk. Glad you enjoy the videos!
Gary Ford thanks, I really enjoy your deliberate and well explained approach. I am very curious how much the measurement changes in different parts of the room with the same dsp, especially from the main listening position.
Collab?
Let's do it!
Hi Gary, i've built a set of active 2 way stereo monitors using a Wondom JAB5 amplifier. Am trying to get my head around SigmaStudio, thanks for your video's, they're very educational :) One question i have, and hope you might offer advice: When i have the ICP1 PC control module connected to the amplifier, i'm unable to get the amp to play any sound. In the instructions from Sigmastudio, it indicates i should be able to tune real time once i've uploaded a schematic to the ADAU1701 chip. I have bluetooth and 3.5mm headphone jack inputs, both work fine when the board isn't connected to my PC.. Should i be able to stream audio to the Amp via the PC control module when connected, or is there a different way to get audio to play? Any suggestions? Thanks! Hugh.
