AIFF is an audio container format that usually contains raw PCM audio (8, 16 or 24 bits, mono or stereo, at any sampling rate)

This old format is very simple: it uses an atoms structure, with common atoms FORM, AIFF, COMM, CHAN, MARK, APPL, SSND.


How to fix a corrupt AIFF file?

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

But for those who are not afraid of using an Hex editor and want to experiment a bit, use this Technique:


Success rate: 100% (Usual restrictions apply, see Expectations)

Technique used: Container structure correction

Tools: Hex editor


If the file is damaged and doesn't open, it's probably because some atoms are not properly written.

If a live recording session has crashed or hanged, the following atoms will not have the proper value set:


Number of audio samples is calculated this way: if data length is 60000 bytes and we have 24bits, stereo, 48000Hz ... i.e. 6 bytes per sample, then number of samples is 10000.


Don't forget to add one of those extensions to the file name: .aif or .aiff

Once repaired, the file can be open with QuickTime directly.
