Multiple audio streams in a single video are supported by OBS and popular video formats, but Twitch strips alternate audio streams from video it receives and offers no way to select alternate audio streams while watching a stream.
This feature came about in order to allow videos to have audio in multiple languages, which is something any streamer is unlikely to do, but the availability of multiple audio streams can allow streamers to make alternate audio streams for other purposes. For example:
1. Those with poor hearing may benefit from a voice-only stream so that game audio, background music, and sound effects aren't obscuring the streamer's voice.
2. A voice-only audio channel may help Twitch create more accurate captions with speech-to-text software that may be confused by background noise.
3. Viewers with good hearing may benefit too simply by being able to mute a streamer's bad taste in music and obnoxious sense of what sort of sound effects are fun to have in a stream.
4. It's not impossible that a professional streamer with the right kind of show might want to hire a translator to open their stream to an audience that speaks a different language.Octapoo supported this idea ·
