It seems, that oggenc-ing audiofile, and then flac-ing diffrences
between original file and vorbis compressed file gives a little better
compression than simply flac-ing. I've tested it on one file only:
file.wav 55829468 bytes
flac -8 file.wav
file.flac 37924329 bytes (0.6793 of original)
oggenc file.wav
file.ogg 4784799 bytes
oggdec -o ogg.wav file.ogg
sox tmp.wav ogg-.wav vol -1.0
soxmix file.wav ogg-.wav rests.wav
flax -8 rests.wav
rests.flac 31353872 bytes
file.ogg+rests.flac 36138671 bytes (0.6473 of original)
Its time consuming, and decoding is harder than for flac, but both
formats are streamable. And what a jump in compression ratio...
