Multicam audio - switch source audio
Look at how you can switch between different audio sources in an Avid group (albeit mono tracks only).
I spent a lot of time trying to get a multicam audio workflow, but could not (this was PP17 but I don’t think it’s much changed).
I ended up using source audio & multicam video.
Ideally, with multicam audio, we should be able to access field audio (ie multiple track wav, with stereo & mono & 3.0/4.0/5.1 etc tracks in the same clip) or audio tracks attached to camera video (again may be stereo/mono etc in the same clip).
Thus you should be able to switch between different sources in the timeline (eg from Cam1 A3 to Cam7 A5)
NB this is not necessarily audio follow video. In Sport, Entertainment & Reality there are a line cut & multiple isolated cameras being recorded. The audio may be on one master bwav and/or routed to the 16 audio tracks on each iso source. Those audio feeds are usually a mix of stereo/mono and in bigger productions include 5.1 / 3.0 / 4.0 & beyond. Adaptive tracks probably offer the flexibility to deal with this but I don’t think it works yet.
