Audio Distortion 

Description:

Severity Structure:

FYI

N/A

Issue

A minor errant effect within the dialogue, or a major errant sound within music and or sound effects

How to Prevent:

Measure signal in as many points as possible in order to avoid introducing distortion.

Solution:

Review the original recording and determine if the effect was in the recording or produced during the mix, correct and re-deliver the print master. Check the M&E to ensure that it doesn't exist there, redeliver M&E as well if it is.

If the source sounds ok, then it's possible that the audio levels were adjusted at some point, possibly during ingestion of the tape master (tape deck was misconfigured), during an edit (audio mixer of the non-linear editor was incorrectly adjusted), or during transcoding (a gain filter was applied).

Return to the point in your workflow where you are able to verify the audio was ok and start re-processing from that point. If you have to take it into an NLE (non-linear editing system) to perform an edit then ensure that the NLE is correctly configured.  When re-transcoding, ensure no gain filters have inadvertently been applied to the profile being used.
