There should be at least two audio channels for the viewer.
So the viewer can decide to switch off background music or game sounds if wanted.

I often have to quit streams because the music game sound is not what I want to hear.

I thought I was the only one who had this idea so I just posted the same request, but I see that I am not alone at all
I wonder myself about the complexity and profitability of such a feature for Twitch.
An audio mixer would have to be created on the client side to handle the two incoming streams. It's a big job.
And for the moment Twitch is only designed to receive one stream per streamer

This would be so awesome ! I came here to suggest the same.
Another step could be to have Multiple Video Channels, especially for webcam channel, where the spectator chooses if he wants to see and drag the webcam box on the stream!

I would love this! Some streamers turn the music ingame so loud or some teammates are hard to understand. That is a feature that has to be as soon as possible. Too bad it seems that it's not getting through.

Create an extension that will allow a streamer to connect to their music source (Spotify, Amazon Music, etc.) and have it as a separate audio stream from their live stream audio (voice/game audio). This would allow content creators and Twitch to simply mute or delete the music stream from VOD's that have DMCA related issues, while allowing the streamer's content to remain available.

would be realy nice. for games like escape from tarkov. i often play myself with the stream on a second sceen. must mute it, because in tarkov you need to hear the enemys. but it would be nicer when i only can mute his gamesound. obs can send multible audio cannels. switching them in the video would be great

Allow the viewers from there devices to control the volume of the streamer and the game. Sometimes I am watching good players, yet very bad talkers so I want to here only the game. I would really like this option.

There are a lot of accessibility, and functionality issues that would be solved with a feature like this.

Examples of accessibility would include multiple audio languages, audio description, etc.

Feature improvements for broadcasters could be Mic only audio stream (for broadcasters who play games with their viewers, enabling viewers to have no noise from streamer game audio when playing the game themselves)

The above assume Twitch only allows for one stream of audio/video to be listened to at once. If Twitch opened up client-side mixing, the features in the top-level post would be possible, as well as the separation of broadcaster voice, team comms, music, game audio with client-controlled audio levels to their preference (some might want full volume game audio, others might want background levels if they are working, etc).

More than one volume bar on viewer end for a streamers voice, game sound, music, etc.

This is exactly what I was thinking too. Would be a great addition.

Seconding

I was just watching a streamer, who played some music I didn't care to listen to, and I got the idea that, what if when the streamer streams, his stream is separated into two streams, one that contains video and sound, as per normal, but he then uses a tool or something to stream his music through. Enabling twitch to seperate the two sound streams - allowing the viewer to turn off the music "stream", or have it on.

I think it would also solve the annoying thing where recorded streams have parts of the recording muted due to copyrighted music being played. Because then both streams would be recorded, and there would just appear gaps in the music stream when playing back the recording - if the music is muted.

Cheers!

It would also help for rewatching VODs where the music channel could just be taken out!

I've been asking for this feature for ages. Literally if twitch and voicemeter came together and just made an extension where streamers could link their mixer settings so people could manually control audio channels it'd make life easier for so many people. That way streamers wouldn't have to tune their audio anymore, music too loud? Viewers would be able to turn it down without making the streamer tab out, or Mods could choose to turn the streamers voice up drastically to avoid missing an instruction etc!

Audio management can be very cumbersome for creators. Whether it’s balancing game audio or discord voice channel audio, it is impossible to please every viewer. By providing content creators the option to stream with 2 independent audio channels (desktop, microphone, etc.) you can allow viewer to independently choose volume levels between multiple sources.

Concordo com a sugestão apresentada. Por exemplo, eu como expectador acompanho um streamer que tem um gosto musical diferente do meu. Nesse caso seria muito bom se tivesse uma ferramenta que silencia a música de fundo sem silenciar o streamer. Caso contrário, eu assistirei somente a VOD e não o stremer no exato momento da live.

What:
Seperate volume control/mute for an additional "new" audio output (streamer defined). Mainly thinking music track here.

Why:
As a sufferer of Attention deficit disorder, i often have a hard time focusing on/hearing the streamer.

Bonus:
Replacing the played music with your own taste and the "having a stream on in the background while doing other stuff" viewing style.

You mean it's still a copyright violation. However, it keeps VODs and clips clean and safe from takedown requests, which is a huge improvement.

This doesn't address DMCA, as you are still technically streaming copywritten music. The other suggestion, that there's a sync link b/w Spotify and the stream where people click and they are listening in sync with the streamer to the music would be better, b/c the audience would be listening with their own private license, but this also doesn't address video lag and syncing in case the streamer sings with the music etc.

I have a suggestion that I do not want to listen to songs all the time on twitch, so add a mute button to the panel for users who want to, and those who want to listen should not listen.

(şöyle bir önerim var, twitch'de her zaman şarkı dinlemek istemiyorum, bu yüzden panele, isteyen kullanıcılar için şarkıyı kapatma tuşu ekleyin ve isteyen dinlesin istemeyen dinlemesin. )
