Streamer have to put music in separate channel so I can optionally mute and unmute it by button.
If streamer config audio this way then new mute icon appears near normal mute.

I would upvote this as well, but Twitch limits voting..... asdf.

Bump!! Could also be integrated with the existing music track DMCA stuff so that streamers don't get flagged unnecessarily

It would be great to be able to control the volumes of a streamers game volume, and caster separately. Example: ESL_CSGO their caster volume is loud and the in game volume is low.

was about to write exactly same thing. I enjoy watching streams while I'm playing myself but I prefer to play listening my own playlist, very often I have to make a choice - Spotify or Twitch.
It shouldn't be hard to implement such option (even if it would be a paid option like TwitchTurbo) since most of streamers steam music separately and they don't include it in VODs.

I think streamers should have option to stream audio channels seperately, so viewers could change their volume according to own preferences. Sometimes you just want to chill to music or focus on the game. Also sometimes it just plain hard to hear what streamers have to say if they have adjusted volume levels badly. I think there should be default volume levels adjusted by streamer and then you could change them

This would be a great feature, its already implemented that the streamer can send a separate audio channel for music. It would be nice if the viewer could lower the music volume locally or mute it entirely if they want to play their own music instead

But why stop with that, having a voice and game stream would allow you to rebalance the audio. Maybe it provides feedback to the streamer if most of their viewers have game volume reduced that their audio levels might need fixing.

There would need to be incentive for the streamer to set this up, and there could be. What if this feature was tied to twitch turbo and available on channels you are subbed to. But the benefit for the streamer could be that either they get an extra 20% from a turbo viewer subbing or that being turbo subbed reduces the cost of subs by $1/£1 so that they are more likely to sub (streamer still gets the same amount for it), I think this could drive more sales of twitch turbo and that is also direct revenue reducing twitches dependance on ads. Is turbo not significantly better per viewer than the pennies twitch might get from an ad impression? This would mean turbo could give viewers a significantly better viewing experience

My biggest gripe with streams overall is it is hard for a streamer to get their audio right all the time, Id be happy to pay for a feature where I can fix it locally rather than hope the streamer notices while getting my ears blasted by endless explosions and gunfire in a game while they have their mic turned so low it could be an ASMR stream

If implemented there would be benefits for everyone, twitch, the streamer, but most importantly the viewer.

Exactly, not everybody have the same taste of music. Even being able to volume down the music that streamer wishes to listen, would be cool. We don't even need to choose the music on Twitch.

Hello, there is an idea with a choice of audio streams. In Dota2, commentators muffle the sound. It would be great if there were 2 threads with no commentators. The fact is that you can watch the stream with music. With two audio streams, you could watch the stream accompanied by music.

In the twitch player settings, add a choice of audio streams.

That would be awesome in full support widepeepoHappy!

@kevinodoo, it doesn't, OBS just gives you the ability to send an audio track through a different channel which isn't recorded on the vod.

OBS already has this feature!

This is something that I've really wanted for a long time over a lot of different services. It would require support on a few levels (streaming software, the streamers themselves, and Twitch of course), but many video codecs already support it. One drawback would be the extra bandwidth it would take (or extra processing on Twitch's end if they decided to mix them together for each user). A potential strategy to avoid that issue is having one or a handful of default balances which Twitch would mix for you (eg. only talking or 50-50), and then an option to have a custom balance which would be processed client-side. Another thing that would be good is a third track for game audio, or (even better) an arbitrary number of tracks chosen by the streamer. I personally spend more time on Youtube than Twitch, but it would be great to see at least one service offering this feature (and maybe it would even become standard).

I'd like to add that this option would be really useful for people with APD or other disorders or neuro divergency that struggle to understand audio informations (such as the streamer talking) while music is playing

What about adding an option/button to mute the music the streamer is playing? Sometimes i don't like the music so an option to only hear the streamer voice would be great.

Hi there, first things first I don't even know if it is possible and how it could be but, i think it might be nice to have differents channels for the voice of our streamer and the music he used, this way we can set the stream audio like we want. We like a streamer but the music he listen to cause you nightmares at night or simply, you find the music too loud relative to the voice you can up the volume or down the volume like you wish and experience the streams like you want.

Like I said, i don't even know if it is possible but it could be nice !

It would be great if streamers could be able to stream multi channel audio, and viewers could have a mixer option so we could adjust levels for ourselves or turn off audio channels in full such as game sound, music, or so forth.

This would have to be enabled from the streamer's end, but would benefit viewers who don't enjoy the streamer's music. Enable a way to control the volume of the music of the stream separate from the rest of the stream content (game sound, mic).

It would be awesome to have the choice to listen to your own music (as a watcher of the stream) while listening to the stream when the streamer puts its own music in the stream. If I were to do it now, there would be my music playing AND the streamer music playing which is just a mess of sounds.

Honestly sometimes I don't listen to a streamer just because I don't want to listen to the streamer music because either I don't like the music background or because I wanted to simultaneously watch something else with sounds on my end and I don't want listening to a mess of sounds (e.g. any other video or music, another stream, etc).

There could be 2 sound channels (1 for background and 1 for other sounds like streamer mic, in-game sounds, etc) with individual volume control (including mute option) handed over to the users. I would see those 2 volume control to be defaulted at equal volume, but at least we would have the option to mute one streamer's music when desired.

Thanks and regards,
David

OBS Studio already supports multiple channels for local recording, so I guess if the Twitch ingest supported multiple channels, it could be easily implemented.

Aside from being able to mute Copyright-violating content selectively, I second the idea that multiple channels would be valuable for viewers wanting to selectively choose what to listen to.
For example, I might want to listen to the streamer's voice, but the game they are playing is too noisy, so it would be cool to be able to disable the game audio.

I think it would be nice if streamers get to choose whether to multi-channel or not (just like when setting up audio channels for local recording in OBS), the Twitch player would only need to offer a combo-box for viewers to choose what to enable/disable.

And if the option to individually edit/delete/upload audio channels on VODs was added, that would open many possibilities, from removing Copyright infringing parts of the audio manually, to uploading replacement tracks, or maybe even adding commentary tracks, or dubbing to other languages... But that's maybe going too far right now XD.
