Tired of reaching for your volume knob every time your mp3 player changes to a new song?
MP3 Gain analyzes and adjusts mp3 files so that they have the same volume. Not all CDs sound equally loud. The perceived loudness of mp3s is even more variable. Whilst different musical moods require that some tracks should sound louder than others, the loudness of a given CD has more to do with the year of issue or the whim of the producer than the intended emotional effect. If we add to this chaos the inconsistent quality of mp3 encoding, it's no wonder that a random play through your music collection can have you leaping for the volume control every other track. MP3Gain does not just do peak normalization, as many normalizers do. Instead, it does some statistical analysis to determine how loud the file actually sounds to the human ear. Also, the changes MP3Gain makes are completely lossless. There is no quality lost in the change because the program adjusts the mp3 file directly, without decoding and re-encoding. |

1. Open MP3Gain
2. Set the "Target Normal Volume" (for example, to 92.0 dB)
3. Click "Add Files," and add mp3 files
4. Do Track Analysis on the two files. Click "Track Gain" to save volume changes to files.
5. Listen to the mp3 files using your favorite media player such as Vidmex. Note how they're approximately the same listening volume
Note, MP3Gain does not decode and re-encode the mp3 to change its volume. You can change the volume as many times as you want, and the mp3 will sound just as good as it did before you started.
