is a necessary program for a music lover, if you listen to some album. It is possible to normalize album tracks so that the volume slider does not rotate in the speakers themselves, and it is very convenient.
Doesn't support values under 85dB or non-English filenames.
Use foobar2000 to add ReplayGain tags to MP3's, it's the best application for that job, at the moment.
It also supports Unicode, so is an alternative to MP3Gain for filenames with non-ANSI characters.
Drag&drop MP3's => Select files => Right-click: ReplayGain => Scan ... => Update File Tags Done!
Doesn't support Unicode, filenames with international characters are not supported. Using MP3GainGUI.exe front end.
I used this a lot on windows, but on linux this is built into the Sound Konverter program, so I just use that instead.
