MP3 files have a gain tag to tell the player how much "preamp" gain to apply to the source. The problem with this is that if you go too high, the MP3's will "clip" or produce sound out of range. I personally use MP3Gain (software) to maintain an even gain across my large library. It will analyze the MP3 after you apply a gain level to tell you if it will clip or not as well. Batch processing is also a breeze.

good to know! Thanks!
