An MP3 file that plays too softly can disturb the flow of a solid MP3 playlist. Amplifying your MP3 file to match the levels of your other MP3s can end the frustration of having to turn the volume up on your MP3 player when softer songs play. And with the help of some free online software, accomplishing this task doesn't require an audio expert.
