Question / Help Separate audio for two Skype guests

[katwitch]

We're using Skype for Creators and I can get separate video feeds in OBS by using NDI. However, if three of us are connected on Skype, all the audio goes to a single mix / track. Is there a way to isolate the audio from each guest / source? Without that, it's a mixing nightmare unless everyone has the same mic and the same room settings, which is not likely.

No. This is how Skype has implemented NDI-- separate video feeds, all with the same audio.

What you want to do is that for each scene, use whatever NDI source is needed for video, and have one source, audio-only-- the same one-- in every scene. But I'm not sure how that does with sync, and there's nothing you can do in this case to process audio from each participant separately.

Ugh. Thanks.

This NDI auto setup is a mess. Both for sync and for levels. If one of the Skype parties glitches even just a little, it throws the sync off.

How about alternate (to Skype) suggestions? We do a lot of video interviews.

None that have Skype's ease of use, no.

I achieve similar results by aggregating individual FTL streams from OBS to Mixer.com, combined with audio only chat using a Mumble server.

Each participant sends audio and video in an FTL stream, those are individual sources in OBS. When a participant's video is in use, the audio also comes from there, and others' audio comes their Mixer streams. This means video and audio are always in sync, and all participants can always be heard, and individual participants audio and video can be processed separately.

It requires each participant be able to setup and run OBS, their own microphone and camera, and be able to stream to a Mixer account. The lag is about 1 second or so.
