gnormalize is an audio converter and CD ripper with ReplayGain normalization
algorithms, a metadata (tag) editor and an audio player. It uses gtk2-perl under GNU/Linux.
gnormalize decodes the MP3/MP4/MPC/OGG/APE/FLAC file to WAV,
then normalizes the WAV to a targeted volume level and re-encodes it. Moreover, gnormalize can
extract Audio CD track and output as various popular audio formats (MP3, MP4, MPC,
OGG, APE, FLAC, WAV) with fast speed and high quality. gnormalize can also convert
audio format between MP3, MP4, MPC, OGG, APE and FLAC with high fidelity, which meets
your need to play and collect audio files. It can change the encoding and Metadata (tag)
properties of final normalized files.
gnormalize can be used to adjust the volume of audio files to a standard
volume level, where different recording levels on different albums can cause
the volume to vary greatly from song to song.
gnormalize uses 'wavegain' to normalize wav files because 'wavegain' is based
on more accurate gain_analysis.c code from ReplayGain to adjust and normalize the sound amplitude.
Supported files format: MP3, MP4 (M4A or AAC), MPC (MPP or MP+ - Musepack), OGG,
APE (Monkey's Audio), FLAC, Audio CD and WAV.
Supported files format: MP3, MP4, MPC, OGG, APE, FLAC and WAV.
Convert from/to MP3, MP4, MPC, OGG, APE, FLAC and WAV;
Support for LAME, FAAC, OGGENC, MPPENC, FLAC and MAC encoders;
Support for LAME, FAAD, OGGDEC, MPPDEC, FLAC and MAC decoders;
Rip audio CDs utilizing cdparanoia or cdda2wav;
Play audio CDs utilizing gnormalize::cdplay or Audio::CD or cdcd;
Play MP3 with mpg321 or mpg123 or madplay;
Play MP4/MPC/OGG/FLAC/WAV with MPlayer/mppdec/ogg123/flac123.;
Support normalization with adjustable sensibility;
Can normalize/convert files recursively into the directory;
Edit and get MetaData like artist, title, album, ... ;
Get MetaInfo like bitrate, time, frequency, ... ;
Includes WaveGain that applies ReplayGain normalization algorithms directly to WAV files;
Read the CDDB entry for an audio CD with CDDB_get;
Start playing when one track is double clicked;
Play tracks considering the straight or random order;
Play tracks that satisfies established filters can be more convenient or pleasant than the general random approach.
The available filters are 'Play Tracks From Different Albums/Artists/Genres/Years'.
For example, if the filter is set to Albums, then play tracks jumping between different Albums.
In this case, all Albums will be played before repeat some Album.
In others words, until one track has been played from each Album, the same Album will not be chosen twice.
