Cleanup, trim, normalize, fade your MP3s without quality loss, using mpTrim
mpTrim is a basic MP3 editor you can use to improve your MP3 collection. It can trim MP3s removing silent or unwanted parts.
MpTrim also adjusts the volume of MP3s. Volume change can be manual or automatic (volume normalization).
The program can fade-in / out MP3s (to fix abrupt beginning or ending), clean-up MP3s and recover wasted disk space.
mpTrim keeps audio quality intact, no matter how many times you process an MP3, because it works directly in the MP3 format without having to re-encode. That also makes it very fast.
