Best way to test would be to record the empty Line In jack in Audacity, both with and without the magic expansion card in the system, then boost the recorded silence by the same amount for both files (say, 500%). Then you should be able to clearly visualize and/or hear whether or not there is a difference.
Indeed. Hearing test like Linus did are the domain of "audiophiles" who buy 5000 USD cables. Let's do some real tests or at least get a proper control group.
Or reverse the phase of one of the signals and sum them up. If it's quiet, there's no difference.
They weren't really trying to test it hence them dropping it and still testing it
@@joelr2214 LTT viewers are gamers for the most part are geeks/gamers and this shit is the kind of stuff that makes sense for audiophiles doesn't make a whole lot of sense for gamers to have and it's the kind of thing people would convince people who aren't that savy with building a gamming rig would be tricked into getting by someone because they were told that the reduction in electrical noise will make it easier for them to hear enemies' location. He tested it in a way that this video would be applicable and make the most sense to the largest demographic of his viewers.
But if you can't detect the difference while listening to a song is there even a point?
The weird thing is is that the second speaker buzzing sound you showed as an example at the beginning actually happens when my computer is turned off. When I turn my computer on then the buzzing stop
That's normal. It's called a ground loop. When the PC is on it drives the audio cable, when its off it just leaves it disconnected. Then, the wire acts as a capacitor, an "antenna" for lack of a better word, for the 50/60hz you get into your speakers over the power supply.
If you unplug it from the computer, it should make the same sound. And if you then bridge the three poles of the connector with something like a metal paper clip, the noise should be gone. Just to demonstrate the effect.
I actually thought to myself while Linus said that that his explanation is nonsense.

Oddly capacitors can be used to clean up and smooth out signals, and clean up power sources.
But not normally when used out of the signal chain, it's the right idea in the wrong place to be really effective.
Ideally needs to be in the PSU XD
actually they need to be near the thing that is doing horrible power consumption, as that's at the end of the conductors pulling the current that is causing the voltage drop across the copper tracks etc.
@@meowland8379 you have it the other way around. Capacitors are high-pass filters which allow AC to pass through and block DC signals
@@youhackforme Capacitors are high-pass filters when placed in the signal line, where they're often used for decoupling and dealing with DC offsets like different ground potentials. They've probably got those capacitors bridging the voltage rails and ground. In that position they'll act as low-pass filters, smoothing out higher-frequency noise. They're going to be too far away from the actual Digital to Analog Converters to do much good though.
@Meowland "Real audiophiles are better off staying away from digital." So, you're saying that instead of mixing and mastering audio on a computer, bands and composers should be what, mixing using Vinyl records and painstakingly constructed analog circuitry customized for every task? Try telling that to Hans Zimmerman or any composer these days.
Mixed analog/digital circuitry is nothing new, and noise isolation between those domains is a major task of circuit board design in those environments. There is absolutely nothing wrong soundwise with using high sample-rate, digital audio for the majority of your chain and finally converting to analog right at the driver stage. That way you can get all the power, signal to noise, transmission, and ease-of-use benefits of digital. Cheap mp3/wma/youtube compression that destroys sound quality? Oh, I'm right there with you. But there are lossless formats that preserve the original audio far better than any analog signal you can create and store.
@@supertim7722 Either in the power supply, or inline to where that power is going.
Playing Devil’s Advocate: Sort of hard to see how a power rail filter works without hooking up an oscilloscope to look for noise.
I honestly doubt all of these capacitors are even getting charged. I mean, filtering capacitors are meant to be *directly* next to the sensitive, power hungry parts. While the flashy caps on this this are dead center of the board... for you know... looks?
@@danjz0404 oh really? Frequency is indirectly proportional to distance of the trace.
They are not supposed to just be near the power hungery parts, they need to be right next to the chip's pins to work. This is where linus was also wrong, they are in pretty much every circuit that uses chips
I also want to point out that he dropped it at the beginning. Who knows if it's even working exactly as it's supposed to after that.
Definitely, definitely...

What beard?
He's finally handsome
I think perhaps the solution you're looking for is actually an in-line isolation transformer on your audio line out. I have a noise problem with some of my audio hardware when my laptop is plugged in, this was the ultimate solution to that problem. Basically, it filters out DC noise allowing only AC through (audio signals are very lower power AC waves). It is important to note that not all 1:1 audio isolation transformers are created equal, with the better sounding ones with the least loss of quality costing a bit of money.
“There was a time, when onboard audio was so bad....” sigh, thanks Linus, way to make me feel my age.... I still find it difficult to talk myself into using onboard audio thanks to having been here for the pc-speaker, and Sound Blaster 16 days of “audio”

"What made Elfidelity think that this was going to work?" - Making money from gullible people. ANY component that can be part of an audio system is ripe for the snake oil merchants - from stupidly expensive audio cables to mains leads and my pet hate - audiophile Ethernet switches. Yes - audiophile Ethernet switches. Utter bullshit.
The solution here is flawed - for a filter to be effective, it has to be put between the PSU and device that you are trying to filter noise going into. This doesn't do that.
Yeah, I feel like that many caps could actually help with noise if they were spliced into the gpu pci power
The only thing this can do is generate a counter wave to the noise.
That has to be PRECISELY tuned to do anything.
Which is why it’s added to headphones instead of speakers.
"And I wrote a children's book!" was the most unexpected segway I've seen him do.
Linus: "That's where this, at least in theory, comes in"
At least in theory it worked before he dropped it
I think that the card works if you have a bad quality PSU and/or non grounded lines.
Just buy USB headphones and problem is solved. That's what I did for my old PC that had this issue. It has "driver" outside the PC, on the cable thingy.
@@WyvernDotRed unfortunately it never would. The problem is that you can't just insert a noise filter anywhere in the circuit and expect it to affect all elements. This is the equivalent to putting a water filter on your sink's drain and expecting cleaner water from the faucet.
@@WyvernDotRed A lot of "ifs" in that statement. IF the capacitors are bad (cheap chinese quality and not good chinese quality), then you have a tech-looking thing in your PC... IF you put it in and leave it there. Most modern motherboards are made to fix many power alternating problems. A good external battery back-up prevents your PC from coming to a complete stop while running and a great one could likely fix your audio problems due to your building's current. A DEPENDABLE PSU in your PC is the foundation on which your PC sits and can not be understated, but many DIY PCs probably do. :)
matrixfull are there really USB headphones so good you could tell the difference in a modern build? Ignoring that the inline dac may be bad
better testing method: run the output audio through an amp and then to an oscilloscope/spectrum analyzer. If you don't have one, then record it with a good quality audio interface and open it up in Audacity to see the waveforms
This implies that Linus does scientific testing without mass comment outrage.
No self-respecting audiophile would ever admit that electrical signals are susceptible to measurement or analysis. (Someone needs to point out that the act of recording sound with a microphone is itself the act of measuring sounds waves. And any property of sound that might exist in an audio recording can be analysed.)
Or at least use powered speakers with a motherboard audio out that isn't well isolated from noise. I can hear my HDD and gpu churning away through my speakers just fine. It would be so much easier for the viewer to hear what electrical noise can sound like through speakers.
Exactly what I was thinking

I am a drone pilot and I have built my own drones and tried diffrent things and can say with complete confidence that capacitors do make a huge difference. It all just depends where you put them. On my drones there is usually one big capacitor filtering directly from the battery and a few smaller capacitors filtering out the reverse signal coming from the motors. And on a computer I would say the best place to put any kind of filtering would be on the pins coming directly out of the power supply.

I run a DJ rig and learned by accident that the best power conditioner is a Battery Backup unit. All other power conditioners are crap and do nothing. I bought what were supposed to be rack mounted power conditioners, well they were rack mounted and had power outlets but did nothing as far a conditioning. So the accident I am referring to happened like this. I was setting up a Studio card and I was plugged into a circuit that also had a refrigerator plugged into as well, every time the fridge compressor started it made a popping sound through the computer which wasn't an issue, I was just testing hardware. One day I got a used Battery Backup and just wanted to see if it worked, I was over joyed that it held a charge and functioned properly. While I had it plugged in I heard the fridge fire up but then immediately noticed zero popping sound coming through the computer, 100% gone and I cranked up the volume to 100% just to be sure and nothing. I ran the system for a week straight and played around with it and never heard the pop again. I now run the DJ Rig at all times with a backup Power Supply plus it keeps spikes from hitting it as well and no abrupt shut downs when we trip a breaker. If you use any kind of coax or RCA cables and want to get rid of fan whine through the speakers you need to use 100% foil wrapped cables, braided cables are only shielded by about 40% to 70% and use as much balanced cabling as possible.
DJ here! This card does make some sense...and also doesn't
If you want good audio u always go the usb audio interface route. Yes usb can cause problems, but they are purely DIGITAL, meaning it's usually sound stopping or some weird artifacts happen.
The most common fix is to get a usb cable with a ferrite filter. I believe this card is aimed at some very specific use case, but I can't quite make up what it would be.

Having a 450$ Motherboard from Asus which already has one of the best audio shieldings out there might not get the point. I have that board too, and it has one of the best voltage controllers from Asus. This board corrects all the noise all by itself easily.
Maybe get a 50$ or 150$ Mother Board without great audio shielding and see if it helps there :)
Agreed, stupid test, start with cheapo motherboard.
it still shouldn't do anything because its not sitting between your psu and the board. it can't filter anything really
Like, if you're buying that thing to clear up your on-board audio, and NOT buying a not-trash sound card... I still don't see the point
@@AsbestosMuffins aaaactually, it can. You should always place all the filtering as close to the drawing component as possible. Having extra capacitors that are literally physically (and electrically as well obviously) closer to the sound card, and I'm imagining someone plugging this right over/under a proper PCI/PCIe sound card, can indeed filter a lot more noise than if it wasn't there.
It is true tho, that it's still too far from the components anyway, that should already have proper filtering anyway. It's rather pointless even if theoretically working.

Are you watching on your fridge?
Your heat is too high if they're crackling

i will be ordering the book very soon. have an 8 month old daughter and son due in may so books for them are something we need. love you brother keep up the great work.
As manufacturers catering to the high-end audiophile market have discovered, this product's biggest failing is its price - if they bump the price up to $4K or more, it'll perform far better (just ask the "discerning listeners" who'll happily pay $7K per metre of "directional" speaker cable). The age-old axiom "a fool and his money are soon parted" applies very well here.
I just realized how young Linus actually is, when he mentioned his first sound card.
Yeah sometimes his references really date me.
I remember a sound card being needed _to have any sort of sound_
yup, PC speaker beeps, then adlib, then sound blaster, followed by sb pro, then sb16, then the AWE32, then the Audigy - damn, those were the days!
yeah, like saving money to buy a multimedia kit for the computer with cd drive, sound card and speakers. good old times

Should have tried recording, that's where the noise floor can be a problem, not to mention being able to view and compare waveforms.
Furman makes excellent power conditioners. I don't really worry about electrical noise, but it's an easy way to protect your gear
"You can insert your placebo however you like." This killed me :D

9:45 I feel so old that I remember when PCs didn't come with any onboard audio aside from a beeping speaker. Wing Commander with beeping speaker vs SoundBlaster was an even bigger change than this youngster is talking about.
My tiny mind exploded when I heard real audio through a pc speaker for the first time with Star Control 2.
May I just humbly count myself to the ppl that remember such stuff aswell, despite being only 26 years old? I grew up with Windows 3.11 and a built-in pc speaker that made the sounds.
And the turbo button!!! From 22 to 28 MHz! :D
I remember putting in a sound card and a CD player to make my machine "multimedia". The CD player was 2X which was awesome then.
@@MC_Papphead Funny thing, turning 'on' the turbo button actually slowed down your PC and turning it 'off' had it run at its normal speed. Sometimes it was the opposite.
Well *_I_* remember when my family didn't even _have_ a PC. Wing Commander with a beeping speaker vs. an empty desk was an even bigger change than _you're_ talking about.
@7:16 "..so you can insert your placebo however you like..." He's already admitting that it's not going to do anything LOL!
Yes, in theory you could make a power-supply-cleaning PCIe card, that could straighten out at least the voltage line sit has access to, by presenting a new parallel load to the line that re-aligns impedance seen by the supply. Though, with how power is drawn from this voltage line, it would probably need some sort of active feedback as well. Maybe not this card, but maybe someone else out there has something for PCIe that works much better.
I cannot believe the merch has spread to the children's book industry

linus drop tips at it's finest :)
I can sleep now knowing that a part 7 is possible...
I made a power filter aka a bunch of caps hooked up to the 12v and 5v rails , as a big buffer . More to smooth out the power when things start drawing power quickly .
I could DEFINITLY see this improving overclocking as well as underclocking
Instead of spending 40 dollars on a sound reducing card, I bought an LTT water bottle and doused my entire system with water and eliminated all of the noise.

As a professional audio engineer, I can say for sure that the external audio interface is the way to go. Make sure to get one that has its own power adapter and doesn't rely on bus power via USB, as that will often carry the same noise from the motherboard to the interface.
Other common causes of noise include: having devices plugged into different circuits from each other, having A/C power cables running near your audio signal cables, having strong RF signals near your audio cables, having electrically noisy devices on the same circuit as your audio setup (e.g. fan, heater, florescent light, vacuum cleaner, etc.).
> having strong RF signals near your audio cables
Which is why front audio can be stupidly noisy on some cases. Unshielded cables that sometimes have to run right by (electrically) noisy components.
Balanced cables also help. I had a ton of noise from my Scarlett and I didn't realize I wasn't using balanced cables. When I switched it was barely a tiny hiss with my speakers at FULL volume.
Lol, yeah I was totally confused as a kid, when I bought a small USB-powered external soundcard for my PC and was hearing the GPU's massive coil whine in my headphones through the USB soundcard. ^^
I also did the "having devices plugged in to different circuits from one another's" thing (apparently, though they were in the same room) and got a really loud hum on my stereo which I used as PC speakers through it's line in. A groundloop filter worked fine and eliminated the hum entirely.
Later I added another input through a splitter cable and connected an older 2.1 PC speaker system, that I got as a gift to the headphone output of the stereo in order to replace its shitty speakers. That setup had me using three groundloop filters to make it work, but it was practical and did sound really good XD
@@leafsoup Yeah balanced cables help a LOT. Onboard PC audio is never balanced, I don't know why, probably to keep manufacturing costs as low as possible.
Don't you need a balanced signal to gain any benefit from balanced cables? And is a balanced signal normally available on a PC let alone an inverter (op-amp or equivalent) on the receiving end to flip the polarity on one of the signal wires and balance the load on the two signal wires?
That is a good point you bring up at 9:36: Most built in sound cards have this that is enough for basic speakers, and if you are like me where you have a more advanced sound system hooked up (I run a vintage pioneer SA-8100 and use a Soundblaster X-Fi Platinum), you're going to have a dedicated sound card with built in power conditioners.
Point is, if you have a sound system that is powerful and clean enough to pick up "dirty" power, then you likely are using a dedicated audio card with these features built in.
Well. If I was worried about noise on the PCI power rails, and wanted to test a plug-in filter that was supposed to help, I would be giving the PCI bus a bunch of chunky stuff to chew on, in order to create noise on the bus. The power supply capacity has a little bit to do with it, although I wouldn't expect a regulated supply to be that voltage-sensitive to current fluctuations. But the resistance in the cables from the supply and the PCI bus copper tracks I would expect to be having some effect. I wouldn't expect to be able to hear it unless my audio card was crap and had sub-standard filtering on its own power supply circuitry. As for coil whine, you're not going to get anything happening with that using a plug-in filter, better off potting the coil if the windings can vibrate. But point is, you need to be looking with a scope or spectrum analyzer to see if the card makes any difference to the voltage on the PCI bus, and it may be dependent on which slot you plug things into.
Considering it looks like a xylophone, I'm going to go with y e s

You're probably thinking of a glockenspiel, but the point stands.

Fit a pci slot plate optical toslink socket to the digital out pins then connect to the optical in on an external dac. As you are streaming pure pcm binary data through a non electrical connection there will be inductance or capacitance distortion through ground loops of radio frequency switching effects from components inside the case.
In theory, shunt regulation can be used to reduce EMI on powerlines. A better solution is to buy a better power supply. I have worked on a medical system that had to have DC isolation and still measure neuron activity in the 1.0 microvolt range.

I just use a USB ground loop isolator. That solves most of my issues since my soundcards are USB based.
same, paid maybe 15 bucks for it years ago
this is news
aaaaaaand there's where i'm going wrong
Just using usb should solve it, since usb is digital. Optical would also solve it.
@@davidjohansson1416 And AC ripple in USB's power line isn't.
Use a good reputable power supply and THEN use optical. This eliminates any noise within the electrical system from getting out through the audio. Any electrical connection no matter how high end still receives noise from the CPU/GPU in it's signal line AND ground. Use optical and end the noise.
Here's how they isolate signals from the mains in a lab setting, use two pm motors linked together with a massive flywheel. Thus no electrical noise from the grid.

@@micahoostdyk6384 tru

"Coil whine" isnt electrical noise. !
Its audible noise created by loose windings in coils much like how a speaker works.
Glue them down with epoxy..unless they are loose internally meaning you'll have to replace them
I was gonna like this comment. But it’s at 69 likes and I don’t want to be “that guy”
"Coil whine" can be generated from vibrations caused by unwanted harmonics coming in the power line to the rotating motor, that cause it to "shake" in certain directions. In very high frequencies, it generated a bit of a whine, as well.
My psu does it even when it's off. Super annoying. Hopefully my better psu coming will solve it 🤞
@@120poundsound2 Well, it means it's not off, right?
I remember my first soundcard. I think it was a sound blaster 16 that my brother and I got for Christmas in the early 90ies. When you say night and day I assume you mean that night is the built-in sound card. Back in those days, there were no built-in sound cards at all, but only the PC speaker. For those who don't know the PC speaker is the little 1/2cm round thing that you plug directly onto the pins on your motherboard, next to the power switch, reset switch, power led and HDD led. Yes, you drive and control it with only the output signal from those pins. Installing that sound blaster 16 was closer to the darkness of the abyss and day. I don't remember the last sound card I got but at some point, I had a motherboard with an integrated sound card and that was that.
One sure fire way to get background noise from your soundcard is to make sure the gain in the mic input is set to high (in the Windows Sound Mixer). If still don't hear it, but you have the option to playback 'whatever you hear', turn that on. That makes sure the high gain noise from the mic input gets heard at all times.
