I'm about to move from 1 file / track to 1 file / disc scheme.
It works great with CDs, but not with DVDs (and I guess BDs too) because they often have separate stereo and multichannel streams, so I have to use 2 files anyway.
How about support for putting them together? (And maybe compressing together?)

Im not sure exactly how this would work with standard WavPack. Since the WAV file format has no support for this, I guess that the source would have to be two separate audio streams/files, and on decoding there would have to be some indication to only decode the desired sub-stream. This would require some API changes to the WavPack library and probably break compatibility with existing players.

However, it looks like RF64 supports having a separate stereo downmix, so if and when that format gets incorporated into WavPack, it should be possible (although it would still require players to be aware of it). I will definitely consider this when I implement those newer formats (I have only done CAF so far which does not have this feature).
