Sent voice audio is delayed ~0.5 seconds.

[CodeF53]

Describe the bug When in a call, audio recorded in Vesktop experiences a delay of ~0.5 seconds before being sent

To Reproduce Apologies for the jank setup, but this is the best way I could think of to reproduce the problem.

In all calls, one person is muted and observes the audio received

1. Start a call using a service other than Discord to provide a static reference audio channel to listen to, I used steam chat
2. Start a call in Vesktop, say some stuff, and observe the difference between audio received in Discord vs Steam Chat
3. Switch to the Discord's native desktop client and say some stuff, and observe the difference between audio received

Reproduction Video

https://github.com/Vencord/Vesktop/assets/37855219/3f6648ea-9b83-40fb-b24d-4a495ab5520e

I start by saying something while connected through Vesktop, and there is a noticeably large delay between audio from steam chat and audio from discord. I then switch to Discord (native desktop client), and the delay between steam chat audio and discord audio becomes very minor.

Additional info Sending party on Windows 11 Receiving party on Windows 10 Testing done on Vesktop 0.4.4 Vesktop and Discord (native desktop client) have Voice & Video audio processing stuff disabled:

• Input sensitivity set to minimum
• Echo Cancellation off
• Noise Suppression set to None
• Automatic Gain Control set to off

Is this just a side effect of Discord web? Can you also perform this experiment in Chromium itself, rather than Vesktop?

[CodeF53]

I will test that next time my friend is on.

Tested in browser (chrome), as well as other discord packages like discord-screen-audio on arch linux, I checked the voice output in your Voice & Video settings:

Vesktop, Browser and Discord-Screen-Audio are delayed compared to the official discord package, so seems to be a web version issue?

[ToRRent1812]

I can also confirm this. Tried armcord and vesktop, both sent my voice with delay.

Try setting noise suppression to Standard or None (i.e. not Krisp). This got rid of the delay for me.

This does not have any effect for me. (see the start of the issue thread, where my tests have all of that disabled). Others should try this. If it works for them, use Nvidia Broadcast or RTX Voice, since they have significantly less delay

My partner on Windows 10 is having the same issue only when running Vesktop, Discord Web is working fine. all audio settings already got played around with and nothing changed. She's using a studio mic, but we also tried lowering the sample rate and it didn't change stuff.

[zxsleebu]

i have the same issue. also the delay is even bigger for me, and my voice becomes choppy for some reason

[graygrotesque]

Same is happening here. Delay is big and I think gets even bigger after some time and my voice is choppy for other people. I can hear everyone fine though

[3ri4nG0ld]

Is there any solution to this?, it is very uncomfortable, especially when I am playing CS2 online with friends.

[Clayrok]

Same problem here. Huge delay compared to the native Discord client. Which is weird cause the official client is made with Electron and uses Chromium as well if understood correctly

[ehabajmal]

Hey, just tested this by stripping out pretty much everything Vencord does except loading https://discord.com/app and concluded that the delay is 99% something with electron.

You can test this yourself by cloning electron's quick start app here and replacing function createWindow() in main.js with the code block below. Login to your discord and then do a mic test (User Settings > Voice & Video > Let's Check). You'll notice the same delay exists.

function createWindow () {
  // Create the browser window.
  const mainWindow = new BrowserWindow();

  // Load discord
  mainWindow.loadURL(`https://discord.com/app`);
}

it's just a discord browser thing, nothing to do with vencord/vesktop. the same will happen on vanilla discord.com/app inside your browser

desktop app uses different vc protocol, web (& vesktop) uses webrtc

Is there a bug tracker, an issue or any way to get updates for this anywhere?

[lewisakura]

This is essentially unfixable for us. We aren't really in the business of writing custom native modules to use Discord's voice protocol, and since it happens on regular Discord web this isn't a bug with Vesktop.
