It's not planned, and also not something we at bitwig would need anytime soon, but I'm open to ideas. The element would be the right place to include a channelMap (comma separated list?) attribute for this.
What would your requirements be?
Any number of sequential channels would cover almost every typical situation. It would be weird to need 3 & 7 as a stereo clip.
More likely example is 3,4 (rough stereo mix done on location) or just 7 single mic (mono) etc.
So start channel index + used channel count would do it. i.e start at channel 3, use 2 channels would end up meaning 3,4.
Any unusual situation could be covered by adding a channel remapping effect to the clip.
You'd still need to say how many channels you want to output (mono/stereo/...), so the comma separated list is probably the best option.
<Audio channels="10" channelMap="3,4" duration="34.21" sampleRate="48000" id="id27">
We can probably find a better name than channelMap though, as it doesn't imply the usage.
Yes. A list of channels used would be fine too. That's how some other formats I deal with do it.
I'm considering adding support for this format.
However I can't see a way for a clip to reference channel 3 out of a 10 channel audio file.
Is this feature planned?
It is pretty important for post production purposes as poly BWF wavs are the norm with different channels for different mics - i.e. 1-2: location mix, 3: boom, 4: lav actor 1, 5: lav actor 2 etc.
I could work around it by splitting all files into mono but I'd rather keep original files intact (with original metadata/timecode etc). Otherwise the format is very lossy when doing a round trip.
