Normalize Your MP3 Volume
Thursday, October 13, 2005
I got a request from a friend this morning. Apparently, when playing songs on his iPod, he has so many different mp3s that are at different volumes that when jumping from one song to the next, it is not unusual for songs to go from low volume to high. Basically, he was looking for any applications that can take all of these mp3s and normalize the audio levels so that all of the tracks are set at the same volume.
I found MP3Gain on SourceForge which is open source software and claims '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.'
So far I have not had a chance to try this application yet so if you have any information, feel free to give me some feedback. I will review this application shortly and do a follow up post.
