MP3 is an encoding format for digital audio that has become that de facto standard of audio compression for playback of music by the turn of the century.
Official name of MP3 is MPEG-1 Audio Layer III (or MPEG-2 Audio Layer III).

MP3 media comes inside a simple .mp3 container, or sometimes inside a video container like AVI, MOV, MP4 when MP3 goes with a video track.


MP3 media is repaired without major problem. Treasured can detect it since 2013 release.

How to repair a corrupt MP3 audio file

The easiest way is certainly to ask our Treasured Repair Service to do it for you.

Techniques used are:

  • Filtering and Rewrapping if it's MP3 alone (no video)
  • Reindexing if MP3 is inside a video container

Quicktime and MP4 tracks use an '.mp3' codec fourcc. MP3 frames are easily identified by their "sync word" FFF followed by 20 bits that are common to all frames (encoding bitrate and frequency).

Example: immediately after ID3 tags (metadata, picture), we have 104 bytes frames starting with ff fb 10 64:
