  • Does this mean ensure users can set AD volume independent of main audio?

I'd be interested in the wider use case for this. Would this be a live stream of someone explaining any visuals in a teleconference or an AD option on pre-recorded videos shown in a webinar? Either may run into problems since the live describer in the former example won't have guaranteed gaps in dialogue in which to add descriptions and people may talk over any gaps in dialogue in the latter.

(Filing on behalf of @JaninaSajka) who also notes that both audio and text descriptions of video may need independent volume/ EQ adjustment or routing. Need is the same regardless of how speech is generated. This is most likely to come up on well prepared screen share content, eg. a video being shared.

Most especially, we want to ensure the RTC platform doesn't strip captions/descriptions that may have been part of the original video simply because it hasn't provided for transmitting them in a screen share.

We should also call out EQ adjustment, not just volume, for hearing impaired people. We know EQ delivers better results than simply adjusting volume.

@JWJPaton @JaninaSajka This looks like new user need / requirements for the section 2.5 Routing and communication channel control.
