It may be possible to use flac for compression. flac is lossless, and supports 
raw input/output streams, multiple channels (so you use left/right for i/q), 
and arbitrary bit depths.

flac --endian=little --channels=2 --bps=16 --sign=signed --force-raw-format 
flac --decode --output-name output.raw input.flac 

Not really sure if endianess/signage ... is correct, try yourself.
