Recording Independent Audio Tracks #22

Open MaxHillebrand opened 3 years ago

It would be AWESOME if the recorder can create a different audio track for each user. This would be very useful for ending up with a higher quality and easier audio-editing, as nobody talks over each other, at least in the recording.

FWIW, this could be "hacked" for 2 person conversation, by having a setting to mute a participant in the recording, and then that party recording locally. It just would be awesome to have it done inside the app, and so that it works even with many participants.

I think this one is going to be a bit more difficult, at least I don't think it's possible using the current recording method, but it might very well be possible using the MediaStream Recording API. I had a look at it for implementing the initial recording, but because each stream is presented individually it would have been quite a lot of work to both record and then assemble the video afterwards. But it would be useful for this feature, and since you don't have the visual element that needs to be assembled any post-processing will be quite a lot easier.

Sounds great.

FWIW, I think the multiple audio track feature will only be used in the case that some post-production editing is done. So I guess we can assume at least some level of human interaction with those files before they are published, and maybe we don't need some post-processing features.

Oh yeah, with post-processing I meant in the more simple stuff like placing the individual audio recordings into one container.

But doing it locally might be better for your use case where the above doesn't really apply.
