Trimming MP3 without touching the quality
Flippy trims MP3 with stream copy: it slices at the nearest safe boundary and copies the data straight across: no re-encoding, no quality loss, and it's near-instant even on big files. Your MP3's encoding is never touched, so a trimmed file sounds exactly like the original: just shorter.

Questions people ask
Does trimming an MP3 re-encode it?
No: Flippy uses stream copy, so the trimmed MP3 keeps the exact original quality and the cut takes seconds, not minutes.
Will I lose quality working with MP3 here?
None. Stream copy moves your MP3's data untouched; only the length changes.
