==== Info ====

1) compressed data doesn't need to be the same for all platforms:
   http://xiph.org/flac/faq.html#tools__different_sizes
   http://sourceforge.net/p/flac/bugs/409/

2) decompressed data MUST be the same (except WAVE metadata are not preserved, --keep-foreign-metadata option may help)
