Compress or Recompress .wav and .flac files
.flac and .wav files can be compressed with the following command.
In this <wav-flac-file> is the path to the music file but can also use wildcards (for example
*.wav).
<compression> is the compression rate.
The highest compression preset is 8.
flac -<compression> <wav-flac-file>
When recompressing .flac files the file does not have to be decoded to encode it again but can be
recompressed in one command.
