gnormalize is an audio converter and CD ripper, which allows
the application of ReplayGain normalization algorithms.
It is also an audio player and a metadata (tag) editor,
based on gtk2-perl under GNU/Linux.
gnormalize decodes the MP3, MP4 (or M4A or AAC), MPC (or MPP or MP+)
OGG, APE or FLAC files to wave, then normalizes the WAV to a targeted
volume level and re-encodes it. The normalization is peformed through
'wavegain', by using the accurate gain_analysis.c code from ReplayGain.
gnormalize can also rip, (re)encode, convert audio formats between
MP3, MP4, MPC, OGG, APE and FLAC, play audio files, and tag properties
of the final normalized files.
