Hello Rene,
If you want to be sure that you get no information loss, I suggest a very
simple test. Recover your WAV file from any of the FLAC files you mentioned in
your e-mail. If this WAV file is bit-by-bit identical to the input WAV file,
then you have no information loss.
Also, it is important to take into account that the compression ratio is highly
dependent on the encoded wav file. If you are processing CDs, the compression
ratio for rock and pop music is tipically 45 % to 70 %. For other kinds of
music such as jazz, the compression ratio may be from 25 % to 40 %.
What kind of music have encoded so far?
