how to record both video and unmixed audio of a group call
Hi,
I need to record a meeting's video as well as unmixed audio stream of the call,
but it seems from the documentation, we can only either record a mixed audioVideo format, or an unmixed multi channel audio format, we can not do both at the same time, I tried to start recording on the same serverCallId 2 times with different format mentioned, that did not work,
is there any way to achieve what I want?

Try below as a workaround:
- Split the Recording Logic
- Record the mixed audio-video using ACS's built-in recording.
- Simultaneously use audio streaming APIs to capture unmixed audio in real time.
- This requires setting up a bot or server-side logic to subscribe to individual audio streams.
- Post-Processing Separation
- Record the full mixed audio-video stream.
- Use audio processing tools (e.g., Adobe Audition, Audacity, or custom ML models) to attempt separation of individual voices.
- Parallel Calls with Different serverCallIds
- If feasible, create two parallel calls with different serverCallIds:
- One for video recording
- One for unmixed audio
- This is complex and may not be practical for real-time meetings.
