Add an option to use the computer audio's output as an audio source.

Being able to side chain duck audio from game. So when streamer speaks, game audio is lowered automatically as per user settings.

I wish I could mute the gameplay audio for myself from my desktop while using capture cards and the elgato chat link. That way, I can keep my volume up on my desktop to be able to hear the twitch alerts and my party can't hear the gameplay come back to them while I'm on mic

It would be nice to have an easy way to "block" out voice from other apps like discord and teamspeak. So that I can stream my voice, what ever I am streaming and music. But leave out the voice of the once I'm speaking with. Incase I don't want their voice on stream or they don't want their voice on stream.

TunesArt is a small app that is on the Mac. It simply displays album art & track into on the desktop, when iTunes (aka Music) is playing. Some music that I have is DMCA free, like any music from the FiXT record label for example. I'd like to capture TunesArt to display what is playing on stream. This is doable in OBS & other streaming software, but I don't see a way to do it in Twitch Studio.

When I used the previous broadcasting program, audio separation recording was possible. I wish there was a Twitch studio. For example, if you put it in a video editing program, only multiple audio appear in one image. The reason I like it can make bad viewers' voices disappear. And it makes my own gossip disappear. This is the advantage.

tts that could be changed to use any language pack and could read off chat and alerts and other information to stream

I wish there would be an easy option to separate voicechat from streams to not make viewers hear what ppl are talking about on discord channels when its confidential/personal matters.

hotkey doesnt recognize my footpedal. It works in discord though

It would be great to auto mute for some layouts (such as "be right back")

For lower end users, streaming, running a broadcasting software and talking to friends while playing slows down their device by miles. Perhaps there's a way to optimise this so that it is possible?

A button where you can look through playlists and search uncopyrighted songs to play in the background of your stream.

When adding a video or an audio file as a media, it would be cool to have the option of having a smooth audio fadding (so that the music is not abruptly cut when switching scene)
This is specially usefull for intro/end of stream scene.

Make it so that my stream only can hear the game instead of everything on my computer. So that I could use discord without my stream hearing.
Thanks in advance,

So when we start the stream there's no camera and music playinf a minute

When streaming with multiple audio inputs each of those audio tracks should be saved separately in the stream recording. This would allow me to take a stream recording, remove my mic track, and preserve game sound. MKV file container would be ideal.

Create function = When playing music. The audience heard the music, but the streamer did not hear the music, as it interferes with the games.

Like, different screens are playing different audio.. say, if I'm talking to a friend on discord and streaming myself making music on Ableton, Twitch Studio can give me a mixer where I could turn down Discord's audio while keeping Ableton's audio in the stream.

be able to add music and a playlist instead of just one song

why would there be a twitch made music player for streams, with no integration to their own app
