Please add support for > 8 channels in audio files. Note that many formats max out at 8 (eg: flac, apple lossless) but some can support many channels (wav, wav64, aiff). I record from an audio interface that gives me up to 48 channels in one wav64 file. I'd like to be able to do "stuff" with this file:

1) channel mapper
2) channel split - can we split by groups of channels rather than just 1 channel per file. eg: channel split with 8 channels in each file.
3) convert (of course)
4) file size encoder

A typical workload might be:

32ch wav64 for 1hr30min (approx 11G) -> channel split (or mapper) to split to 4 files (8ch each) --> save to tmp file
each file -> file size encoder (many formats have 2G or 4G file size limit) -> aiff -> save to final file

Or variations on that.
