Trimming M4A without touching the quality
Flippy trims M4A 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 M4A's encoding is never touched, so a trimmed file sounds exactly like the original: just shorter.
