"Didn't work. Changed bit rate by 90%"
Very small, quick download, mostly intuitive, no install.
Contacted mp3trim support, got advice, but couldn't make it work. Tried aggressive mode per support. Still didn't make a trim change (checked with another mp3 editor with visual display). Also, bit rate went down from 87 kbps VBR to 8 kpbs. Useless.
