Normalize MP3 volume even in Album mode, with MP3Gain

MP3Gain is a free Windows application that analyzes and adjusts mp3 files to bring them all to similar loudness without any quality loss. This way, you don’t have to keep reaching for the volume on your mp3 player every time it switches to a new song, and you can record your cd anthology without editing separately each and every file.

MP3Gain operates in two modes. Radio mode allows a mix of unrelated songs to be volume-corrected to a selected level. MP3Gain calculates the volume level for each song individually. It then corrects each song to make its volume level match the Target Volume.

With Album mode, you want some songs to be noticeably quieter than other songs, just like they are on an album. If you’re playing a classical CD, you expect the track with the flute solo to be quieter than the track with the big full-orchestra finale. Album mode allows you to correct an entire album while keeping each song’s volume level relative to the other songs.

MP3Gain works only with MP3 files; if you need to normalize Wav files, try WaveGain.
