Audio Clipping 

Description:

"Audio Clipping" is the effect in which the amplitude of an audio sample exceeds the maximum playback level, causing audio distortion in the playback system. Commonly referred to as "Over-Modulation".

Impact:

Audio Clipping impacts both the Content and Technical Quality of the Asset. The customer experience is negatively impacted by audio playback that may loudly pop, "crunch" or have decreased dynamic range.  Typically not creatively intended, anything derived from this mezzanine will produce poor or unusable derivatives.

Severity Structure:

FYI

N/A

Issue

A significant portion of the audio appears to peak at an arbitrary level, audio sounds loud and distorted, across music, dialogue, and sound effects. Audio appears flat on the waveform and sounds over-modulated.

How to Prevent:

Monitor audio levels closely on set in order to avoid recording overmodulated audio. During mixing stage, use limiters to avoid clipping.

Solution:

Possibly a normalization error, please review the re-recording mix session, and adjust for a new print master. Check the M&E to ensure that it doesn't exist there, redeliver M&E as well if it is.
