I'm surprised the AI knew that Linus wasn't a child and didn't block out his voice

I really thought he was going to say that Linus was going to act like a child, to see if it blocks out the noise xD But i was wrong there.

This needs to be immediately implemented on all consoles with absolutely no option to turn it off.

You can use it on incoming audio too, so even if they have a loud place you can have clean audio

From an AI perspective, a static sound like a fan is far easier to 'mute' than unexpected dynamic sound such as children and drumming
Debarka
@Annas I didn't understand what you said, but I'm sure you're right
Annas
@Debarka that's great it's easier for the AI to learn it then just throw a massive AI on millions of audio and it will be able to remove any noises
Debarka
@Annas I don't think you understood what I said. You don't need AI to remove a static sound like a fan. Existing noise cancellation technology can do that pretty well. Using AI for static noise cancellation is like using a nuke to blow up a car.
Annas
@Debarka then try it yourself you just scared of how good the AI is

I accidentally left it on when trying it out for the first time a couple minutes ago. I had it on the setting where it gets rid of background noise from incoming audio so when I clicked on a jimmy fallon clip to see him play with baby bears I realized it can edit out laugh tracks! I tested this newfound power by pulling up a clip of Friends and no laugh track, just 2 seconds of silence after every joke. This is amazing.

@Kekkai_ u need rtf for rtx broadcast but u only need gtx with 410 drivers or higher for the rtx voice

Rtx voice is for GTX cards xd it just works on RTX cards also actually if u have a RTX card then install Nvidea Boardcast it has all rtx voice features +background removing or virtual BG without blue screen :)

i mean unless you playback audio live it shouldn't change your awareness on the kids lol its doesnt delete sound from existence

It's *dynamically* (that's the A.I. part) applying multiband compression to block out most other frequencies apart from your voice while using the buffer to sample your voice in order to establish which frequencies it needs to keep. This is why you can hear the amplitude of your voice ducking when you turn it on because some of the frequencies of the noise overlap with some of the overtones of your voice.

This has got to be the most useful video from LMG that you guys have released that applies to so many users. Don't know why you only put it on ShortCircuit, because this thing is amazing.
Ricardo Pesenti
Wow, this is amazing! It does dampen or even distort the voice with very loud background noise but is stil worlds better than without. I am completely amazed! Now we need this active in trains and busses xD Kids screaming but nobody can hear them without having to wear huge headphones with noise canceling AND listen to loud music ^^

@Nocturnal101 Ravenous I told you i know games use hybrid method I said games don't use 100% of the ray tracing techniques. Nvidia use ray tracing in games and they used it in a very clever way. They separated the ray tracing mapping for shadows edges and reflections (which also includes all the effects like global illuminations etc) They even quoted it out in their official announcement. They still use the old rasterization technique ( the good old "shader model" standard) on drawing the shadows but uses ray tracing (only partially) to create better global illumination effects in games like shadow of the tomb raider. Also the wiki is not necessarily right every single time. path tracing is a technique that created in 1986 to solve the problem ray tracing have (the more times a ray is bounced back by objects the more ray is produced in order to track its actual possible routes) And they solved it by doing the "blind attempt", which means that when a ray hits something, instead of calculate every single possible reflect angle, it randomly choose a next direction to go. that's the main point of the path tracing. And it's also the main problem of path tracing, when the SPP is too low, it'll have some serious noise on its image. At the last section of my last reply I was talking about how I don't study rendering methods a lot and that out of all the realm of computers, x86 CPU architecture is my major. I was talking about hardware, HARDWARE.
Dayne Hidalgo
I’ve been streaming with this since the day I saw this video, so 3 months now. For 90% of the time, it’s amazing. The problem is, I’ve found the problems. First problem is, rtx voice filters out loud cheering and laughter. That is a major issue for someone who streams and records highlights. Many stream highlights involve those two things, and the clips are somewhat ruined by the distortion and muting that happens. Second less annoying issue is that when I’m heavily taxing my pc by streaming on one monitor, playing a game on another, and having the stream up on another, on top of discord and Spotify, rtx voice will start to sound choppy and robotic. This problem I haven’t had for very long so I haven’t been able to do a ton of troubleshooting. So I know it’s in beta, but these two things seem very solvable. Main issue seems fixable by a small algorithm tweak. Other issue is solved by just sacrificing some multi tasking, or maybe something I haven’t tried. Overall, amazing but imperfect

Nvidia is one of the few legit AI companies at this point. They a lot of AI development tool kits for their cards and they make autonomous vehicle level 2+ kits.
RubberFistFight
I just started using this on my stream and LPs - I was literally talking into the mic whilst also clapping directly into it. It picked up my voice near-perfectly, but the clapping was completely blocked out. It's witchcraft I tell ya. Also It definitely reduces the overall volume of the signal but you can make it up with a gain filter at the last stage if need be.
Kornelius Briedis
@Domi From my tests, RTX Voice only degraded the low-quality mics, a good one has no quality difference. I was hoping to use it with my headset's mic and that one sounds much worse just by switching rtx voice on, while the snowball mic sounds identical with it on or off.
Domi
unfortunately it also degrades the overall quality and can introduce weird artifacts even without any background noise. the better solution is just having better recording conditions if you are doing this stuff (semi-)professionally. ai based sound filtering is much better suited for stuff like online meetings, where perfect quality doesn't matter and you just want to have minimal background noise.
DiabolusArts
Thanks for showing this, I've had real issues with mic volume and background noise where I live and this should be really good to help with my streams!

For something like the kids or keyboard though the quality loss honestly seems quite minimal.
Kiritaku
I've just tested this myself with a mechanical keyboard. I am impressed. I recorded my mic and rtx voice with obs on different Tracks for comparison. It is insane. As long as you are not hammering your keys the quality is slightly deeper but nothing that would bother you in voice coms. If you go for video Production you can just edit the audio - though I have not tried that yet. I just think it can become a problem for streaming.
Steven Johnson
true, but a 10% reduction in quality for a 95% reduction in background noise is totally worth it.
Personality Of Brick Wall
if you have the AC/Fan on or your PC is full throttling in summer heat, an adaptive noise suppression software is greatly appreciated. it was either get pro-grade hardware and spend a few days/weeks fine tuning or pay adobe for Audition and try to sample every noise profile. this takes advantage of your gpu and be time-saving/stress free. if you have kept noise to a minimum, the change would be minimal.
Gouache
I think this is the same technology Izotope used on RX 7, where there was a new device that allowed this kind of treatment called Music Rebalance. I think this is kind of a gate that reacts to specific human frequency range preset, I'm sure it's more complex than that but I was as surprised as you when I heard what it was doing to audio in separating complete music files into separate stems, not perfect but very impressive.
