[Flac] FLAC suddenly compresses more - why?

[Fernando Alberto Marengo Rodriguez]

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?
Regards,
