mpTrim è un editor per files MP3 che consente di:

• trim MP3s - removing silent or unwanted parts.
• adjust the volume of MP3s. Volume change can be manual or automatic (volume normalization).
• fade-in/out MP3s (to fix abrupt beginning/ending). mpTrim can clean-up MP3s and recover wasted disk space.
• 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. That also makes it very fast.

Oltre alla versione freeware, ne esistono due a pagamento: mpTrim PE e mpTrim PRO, con più funzionalità.
