Normalize MP3 and CD audio tracks for equal volumes.

Not all CD audio tracks are created equal and while professionally produced discs normally have acceptably normalized tracks, not every one does. Different gain levels exist and MP3Gain was created to tackle this.

This program analyzes and normalizes the MP3 files you select and it optimizes them without a loss in sound quality. If you're unsure about making changes to your MP3 file, MP3Gain gives users the option of analyzing the suggested changes before actually writing them to disc.

If you have a large MP3 collection, it may take a lot of time to go through each MP3 file and normalize the sound.. though with MP3Gain, it takes considerably less time. It also comes in handy when selecting a folder before burning the tracks to disc.
