AAC is MP3's better-trained successor: cleaner sound from the same number of bits. Advanced Audio Coding: the default soundtrack of YouTube, iTunes and most MP4 video.
- Born
- 1997, an MPEG all-star team: Fraunhofer, Dolby, Sony, AT&T and Nokia
- Type
- audio · lossy
- Typical size
- similar to MP3, but it sounds better at the same bitrate: or the same at about 25% smaller
- Plays on
- Apple everything, YouTube, Android, modern players; patchy on legacy gear.
- Fun fact
- Every song Apple has sold on iTunes since day one has been AAC, not MP3.
Trimming AAC without touching the quality
Flippy trims AAC 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 AAC's encoding is never touched, so a trimmed file sounds exactly like the original: just shorter.

Questions people ask
Does trimming an AAC re-encode it?
No: Flippy uses stream copy, so the trimmed AAC keeps the exact original quality and the cut takes seconds, not minutes.
Will I lose quality working with AAC here?
None. Stream copy moves your AAC's data untouched; only the length changes.
Is this AAC trimmer really free?
Yes: free for everyday use with no daily cap, no signup, and your files delete themselves from our servers within an hour.
