Error Code:

Audio Pop

Description:

"Audio Pop" is an audio artifact that manifests as a non-diegetic signal amplification. It is visible on the waveform as a spike in signal.

Impact:

Audio Pop impacts the Content and Technical quality of the asset. Loud pops can be distracting to the customer experience.

Severity Structure:

FYI

Pop is under dialogue, not distracting or is a mouth noise from the actor.

Issue

The pop is very loud, stands out in the mix and distracts from the creative viewing of the content.

How to Prevent:

Be aware of inadvertently inducing pops during mix/ edit.   Run through automated de-pop. Also, complete full review of all audio elements as they interact with each other in the final mix.  Manually “clean up” any anomalous audio pops.

In some cases audio pops are caused by vocal performances. These can be avoided by placing the mic further away from the actor’s mouth, placing the mic above or to the side, and/ or making sure to use a pop stopper.

Solution:

Isolate pop and add a 3-4 frame constant power fade to smooth out the anomaly.  Keep in mind, this should not significantly alter the final mix. Check the M&E for the same issue, and redeliver M&E as well if necessary.

If pop is loud/ distracting in the dialogue, replace with either alternate production audio or ADR.
