Enable Streamers to use multiple audio tracks to stream their content
I often watch two or more streamers who host shows together on twitch. This means they will be talking on teamspeak and broadcasting this teamspeak conversation on each stream. This means you will have to mute one of both streamers if you want to watch both of em at the same time. If streamers could stream multiple audio channels, they could stream the teamspeak conversation on one track and their normal microphone/stream sounds on other tracks. Users could mute the teamspeak channel if they want to watch both streamers, and still hear whats going on if one streamer mutes himself on stream (and the additional stream sounds from the streamer that right now will have to be muted)
As far as i am aware rtmp does not support multiple audio tracks per stream BUT rtmp supports 7.1 and according to obs twitch also supports proper 7.1 sound. That is 8 channels that can be used as 4 stereo channels or 8 mono channels or some combination of the two. That would also require software side support (OBS etc.) but should be possible.
Also, if the game sound was on another track, we could adjust the various volumes to our own preference, rather than distracting the streamer with our demands.
Would love that. There is also a reddit post about it: https://www.reddit.com/r/Twitch/comments/7nn2yj/twitch_needs_two_audio_streams_that_allow_users/
Likewise, streamers could stream their Spotify to a separate track and the game audio to a different track. That way the viewers could mute the game or the music if they don't want to listen to it. They should also be able to boost the game or music or streamers voice if they so desire. The possibilities to this are almost limitless.
Best part about this is OBS Studio already supports multiple audio tracks, so it should, at least in theory, be fairly easy for the OBS developers to add this assuming, Twitch made the upgrade to support it.
