mpTrim trims MP3s into smaller file sizes. mpTrim adjusts the volume of MP3s. Volume change can be manual or automatic (volume normalization). mpTrim adds fade-in/out MP3s to fix abrupt beginning/ending. mpTrim can clean-up MP3s and recover wasted disk space. mpTrim keeps the music quality intact, no matter how many times you process an MP3, because it works directly in the MP3 format without having to decode/re-encode, which also makes it fast.
