Isn’t it quite cumbersome to fiddle with the volume slider every time a new song is played? Some tracks are in deafening high volume, while others hardly reach our ears. If you have been looking for a way to normalize the sound across a number of soundtracks, and that, too, without any loss in quality, then QMP3Gain is probably what you need. It’s an open source application that provides front end for MP3Gain engine, a robust volume normalization engine that losslessly adjusts the volume across all the selected tracks – particularly effective in normalizing a whole album. Most volume normalizers gain boost in volumes via peak normalization; contrary to the norm, MP3Gain engine does statistical analysis of the file and makes adjustments without re-encoding.
