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.
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.
@@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.
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.

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
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.
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?
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
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 :)
@@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.
They’re a Chinese company, scamming is the name of the game over there. You want the late-stage capitalism that idiots bleat on about in the west? Look to China.
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.
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. :)
“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”

Card that he just dropped, heavily. I mean to be honest, if there's no problem to fix its existence is not needed regardless, but it's not like there was any other possible result given that information.
Depends on what the card should solve. There was also a chance that this card inserted causes issues which would fix the „Can’t find a problem“ part. :)
"We built a worst case scenario!" No...no you didn't, Linus. Come back when you have a PC where you can hear the mouse move through the headset. It's maddening. This video is dumb.
"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.
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?
It is not just onboard audio you are limited to. I remember using the audio on gpu to play games because I hooked the onboard to some musical equipment. The gpu audio was great too.
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 love how LTT can get me to watch a review for product I've never heard of, and would never consider buying, and still make it entertaining and educational
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.
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
@@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.

"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.
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.
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.
I'd love to see a repeat of a test like this, but with a setup where cross talk is confirmed to be a problem and/or an oscilloscope is hooked in to see the effect.
same, or maybe with a pci powered gpu. MANY electronics are under-filtered. I've soldered up some LC filters and ground loop isolators , and terminating resistors for off the shelf audio equipment and seen a huge difference.
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.
Linus you plugged the headphones into the "line out" jack at the back of the motherboard, that one is meant for active speakers or amplifiers. You need to plug sensitive earphones like IEM's into the front panel HD audio jack and then you'll hear a ton of noise. Also you should try using RTX GPU's for the test as they are notorious for corrupting the power line and introducing a lot of noise into audio equipment including microphones.
I'm confused, if plugging it into a front jack causes noise that is solved by plugging into a line out jack on the motherboard directly, what's the point of spending an extra $40 when you'll have to plug into the back to use that solution anyway?
Xanthelei shortness of cables, or, if you’re like me, the ability to switch between speakers and headphones without having to constantly go behind your tower to switch cables out. Not that I would buy this thing, I just bought some $15 usb sound card off Amazon
Yes, IEMs would be a better choice. He needs something with a low impedance and high sensitivity to bring out noise since the lower amplifier gain is what usually raises the noise floor to audible levels. Those Grados are 32ohm and 100db/mw which is still pretty low impedance and fairly high sensitivity, but IEMs are often even moreso.
The reason why the front IO sounds garbage is because they allways sell them with crappy unsheilded cables that pick up all the noise from everything in the case.

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.
THANK YOU! You're the first one that brought acknowledgement and a good solution for my problem with my tiny 3W (RMS) Loudspeakers that i have solely for the purpose of cheap bass woofers (via software equalizing i can achieve them to play only below certain frequency). Basically i'm on a very cheap laptop, it's not a problem with headphones but it is a big deal when using those kind of cheap loudspeakers, the electrical noise is so disgusting - The Hard Drive writing and reading while i'm copying a file from my main drive, my cellphone when i'm copying a file from or to it even my MOUSE MAKES THOSE SOUNDS and it's pretty annoying. Thanks to you i finally figured out why that happens and i can finally search better ways to fix it without building another system (which, ironically i can't afford although i have invested quite a lot on sound).

As a more genuine word of advice, download 'LatencyMon' and run it for a while. This program will (among other things) check for processes that commonly cause interference issues while playing music, the type to cause crackling/micro-stutter in songs. A stable system should have very minimal latency, if you don't then the program will tell you exactly what the offending process/driver is. As someone who was having background driver conflicts that made my music unbearable and which were very hard to diagnose, I felt the need to give this small psa ^^ Edit: This isn't at all related to power delivery or audio 'quality', it's simply a way to gauge how stable of a platform your PC is for playing audio.
@@morpheas768 Ofcourse, this is purely software based. I've typically had far more issues with software than with hardware audio-wise, at least in the past few years (hence my recommendation).
DUDE!! Thank you!! I've always had this issue, it usually creeps back into my life after a format, or new/different computer. It's one of the main reasons I am reluctant to go a little longer without formatting. Latency is a big deal, and if you don't have it, you won't notice/relate to it as an issue when someone says they have bad latency. Either they're some kinda weird-o stuck living in a 0.2 millisecond past, or.. no that's just it, they're some kinda weird-o that doesn't know what latency is. Just like all these guys commenting to correct you, their minds jumped so far ahead to keep up with the lag, they completely skipped over the name of the program... 'LatencyMon'
I had a motherboard that made a huge noise on the audio output. So I aquired a 10€ USB Soundcard (TerraTec Chipset, I think) and the difference was like night and day. Since they don'T last longer than 3 Months (Solderings break) I got me an external Soundblaster "Card". So happy with it!

@@mooplex4466 What I want to see is if it can filter out the noise that is caused by listening to audio from a device that is being charged/powered by USB.
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.
While I think it's great that you review audio stuff, when evaluating a product claiming to reduce the audio noise floor, maybe you should consider actually measuring the noise with and without the card
@@jc.1191 not necessarily. It would depend on the machine’s devices and how much noise they’re injecting into the power rail. The noise hear on the inductor doesn’t mean a lot. If you look at any integrated circuit on a PCB you’ll notice that it has small capacitors next to it (a good example being older CPUs with capacitors on the bottom). These are decoupling capacitors that help to filter high frequency noise. Different values and different technologies provide filtering for different frequencies. Without getting too deep into EE, this card probably helps to filter low frequency oscillation from mains and the overtones from the fundamental. As it wouldn’t be close enough to the specific components to filter higher frequencies. However, without Linus actually using test kit to explore how well the filtering works, we have no way of determining its efficiency but for ‘Linus can’t tell a difference.’ Which is far less than scientific.
A couple thoughts, as an electronics engineer, on things you didn't mention: - Capacitors should be placed nearby the source of the noise or nearby the peripheral you want to protect from noise. More specifically, there should be no alternative path for the noise *but* the capacitor before getting a chance to go to the rest of the system (when placed near the source), and there should be no alternative path for the component you wish you keep noise-free to draw power from *but* through the filter. Capacitors work by negating trace or wire inductance by being placed nearby components. We're talking millimeters or a centimeter or 2 *max* . Placing capacitors in random places like this, I would say, can actually make noise/EMI *worse* , because now you have capacitors (which act as shorts for high frequencies) creating high-frequency current loops. - This board actually contains a lot more than 7 capacitors. Those rows of aluminum cans? All of them are caps. And those rows of red boxey things below/above those cans? Also capacitors. - The values on those big caps are going to do *nothing* for high-frequency noise. The way capacitor filters work is bigger values filter out lower-frequency noise, lower values filter out higher-frequency noise. Actually, capacitor filters should be tuned to the exact frequency you want to filter out, and should be tuned to the circuit they'll be applied in. - Inductor/coil whine is more likely to happen under low loads, so the remark of "it's not even doing anything" isn't that surprising. Coil whine usually happens when the voltage regulator has gone into something called "pulse skipping mode" or "discontinuous mode". See, usually voltage regulators will work in the hundreds or thousands of kilohertz, so we don't hear them. But if there is only very little current being drawn through them, they can improve efficiency by skipping pulses or lowering the frequency. This behaviour though causes more voltage and current ripple as well as inducing audible harmonics. It's this low-load condition that's actually tougher on EMI, rather than a higher load condition, where the coils and capacitors only have to filter out an exact switching frequency. What's more, this coil whine is *created on the GPU* and no external filter is going to fix it. - To me it's hilarious that they added RGB on this card. I didn't make out the exact driver, but most LED drivers are themselves switching power supplies, adding more noise to your system. Edit: Actually, I don't see any driver. I think they're just using a resistive dropper. No noise then.
There's another type of coil whine that has the same frequency as the framerate. It occurs especially at medium load and high fps when there's different load levels at different parts of processing the frame
"you can put it in a 4x or 16x slot", yeah you can even put it in a 0x slot (leave it on the bottom of the case) and it works just as well.

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.

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.

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.
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. :)

"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?
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?
It is not just onboard audio you are limited to. I remember using the audio on gpu to play games because I hooked the onboard to some musical equipment. The gpu audio was great too.
I just use a USB ground loop isolator. That solves most of my issues since my soundcards are USB based.

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.

"It fell pretty flat, it's probably fine."
Linus, shortly after the birth of his children.
Linus you plugged the headphones into the "line out" jack at the back of the motherboard, that one is meant for active speakers or amplifiers.
You need to plug sensitive earphones like IEM's into the front panel HD audio jack and then you'll hear a ton of noise.
Also you should try using RTX GPU's for the test as they are notorious for corrupting the power line and introducing a lot of noise into audio equipment including microphones.
I'm confused, if plugging it into a front jack causes noise that is solved by plugging into a line out jack on the motherboard directly, what's the point of spending an extra $40 when you'll have to plug into the back to use that solution anyway?
Xanthelei shortness of cables, or, if you’re like me, the ability to switch between speakers and headphones without having to constantly go behind your tower to switch cables out. Not that I would buy this thing, I just bought some $15 usb sound card off Amazon
Yes, IEMs would be a better choice. He needs something with a low impedance and high sensitivity to bring out noise since the lower amplifier gain is what usually raises the noise floor to audible levels. Those Grados are 32ohm and 100db/mw which is still pretty low impedance and fairly high sensitivity, but IEMs are often even moreso.
The reason why the front IO sounds garbage is because they allways sell them with crappy unsheilded cables that pick up all the noise from everything in the case.
Therefore using the back IO for this eliminates that and allows you to actually test what the card is doing rather than eveything else.

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.

As a more genuine word of advice, download 'LatencyMon' and run it for a while. This program will (among other things) check for processes that commonly cause interference issues while playing music, the type to cause crackling/micro-stutter in songs. A stable system should have very minimal latency, if you don't then the program will tell you exactly what the offending process/driver is. As someone who was having background driver conflicts that made my music unbearable and which were very hard to diagnose, I felt the need to give this small psa ^^
Edit: This isn't at all related to power delivery or audio 'quality', it's simply a way to gauge how stable of a platform your PC is for playing audio.
This cannot actually diagnose a horrible motherboard or some other kind of hardware related issue that is causing the crackling audio however.
@@morpheas768 Ofcourse, this is purely software based. I've typically had far more issues with software than with hardware audio-wise, at least in the past few years (hence my recommendation).

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.

If you look at any integrated circuit on a PCB you’ll notice that it has small capacitors next to it (a good example being older CPUs with capacitors on the bottom). These are decoupling capacitors that help to filter high frequency noise. Different values and different technologies provide filtering for different frequencies.
Without getting too deep into EE, this card probably helps to filter low frequency oscillation from mains and the overtones from the fundamental. As it wouldn’t be close enough to the specific components to filter higher frequencies. However, without Linus actually using test kit to explore how well the filtering works, we have no way of determining its efficiency but for ‘Linus can’t tell a difference.’ Which is far less than scientific.
If I worked for Linus, I’d buy two of everything. Just incase he drops it.
I didn’t skip your book sponser, that’s really cool :)
1:58 For a second I thought he was making the humming sound on his own! LOL ! I was like, dang!...he HAS been doing this a long time!
Evidence that Linus is a robot!
A couple thoughts, as an electronics engineer, on things you didn't mention:
- Capacitors should be placed nearby the source of the noise or nearby the peripheral you want to protect from noise. More specifically, there should be no alternative path for the noise *but* the capacitor before getting a chance to go to the rest of the system (when placed near the source), and there should be no alternative path for the component you wish you keep noise-free to draw power from *but* through the filter. Capacitors work by negating trace or wire inductance by being placed nearby components. We're talking millimeters or a centimeter or 2 *max* . Placing capacitors in random places like this, I would say, can actually make noise/EMI *worse* , because now you have capacitors (which act as shorts for high frequencies) creating high-frequency current loops.
- This board actually contains a lot more than 7 capacitors. Those rows of aluminum cans? All of them are caps. And those rows of red boxey things below/above those cans? Also capacitors.
- The values on those big caps are going to do *nothing* for high-frequency noise. The way capacitor filters work is bigger values filter out lower-frequency noise, lower values filter out higher-frequency noise. Actually, capacitor filters should be tuned to the exact frequency you want to filter out, and should be tuned to the circuit they'll be applied in.
- Inductor/coil whine is more likely to happen under low loads, so the remark of "it's not even doing anything" isn't that surprising. Coil whine usually happens when the voltage regulator has gone into something called "pulse skipping mode" or "discontinuous mode". See, usually voltage regulators will work in the hundreds or thousands of kilohertz, so we don't hear them. But if there is only very little current being drawn through them, they can improve efficiency by skipping pulses or lowering the frequency. This behaviour though causes more voltage and current ripple as well as inducing audible harmonics. It's this low-load condition that's actually tougher on EMI, rather than a higher load condition, where the coils and capacitors only have to filter out an exact switching frequency. What's more, this coil whine is *created on the GPU* and no external filter is going to fix it.
- To me it's hilarious that they added RGB on this card. I didn't make out the exact driver, but most LED drivers are themselves switching power supplies, adding more noise to your system. Edit: Actually, I don't see any driver. I think they're just using a resistive dropper. No noise then.
There's another type of coil whine that has the same frequency as the framerate. It occurs especially at medium load and high fps when there's different load levels at different parts of processing the frame
