Treasured's Movie Repair Guide -- Stutter in repaired AAC files

Symptom:

Repaired AAC audio gives problem during playback. After a few seconds, the audio track starts stuttering, and later it becomes silent. But if playback is stopped and started again, audio works fine for a few seconds, then the problem appears again.


This happens because AAC repair is not perfect. The small errors in the repair tend to accumulate during the playback. The real playback time drifts with respect to audio time, thus creating small silent moments (stutter) that grow until becoming continuous silence.


Advanced AAC repair techniques, introduced in 2009, have solved this problem.


Solution:

Open your AAC file with QuickTime Pro or SimpleMovieX, and export it to WAVE format.

It creates a file that no longer stutters. Granted, it's bigger in size, but quality is still the same as original and the problem is gone.
