Geek Software of the Week: MP3Gain!
Tired of MP3 files that are too loud, or have segments that are too loud? MP3Gain “normalizes” the audio in an MP3 file and “corrects” the problem! It is free, and it may just be the “trick” that you have been looking for to fix those files that that were annoyingly loud, but that you don’t want to lose!
“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.”
