Error Code:

Audio Artifact - Hum/Buzz 

Description:

An electrical noise that is captured by signal interference typically caused by an electrical ground-loop in the re/recording signal chain. 

Impact:

Hum impacts the Content Quality of the asset. The customer experience could be negatively impacted if unintended environmental noise is present during the program. Hum could obscure effects or music, sullying the overall quality of the mix. Possibly creative intent on the part of the producer. Any audio assets derived from this source will contain hum.

Severity Structure:

FYI

Hum is low in the mix or is taking place in a scene where equipment shown would be causing it, is obviously creative intent.

Issue

Hum is loud, obscuring dialogue or is in silence and does not have a discernible source.

How to Prevent:

Isolate and eliminate noise caused by a ground loop in an audio circuit with ground loop isolators. The isolator ensures that the shield ground on each audio cable is isolated from any equipment ground, which could cause audible noise when amplified.   

Solution:

Replace the audio with wild track tone underneath to remove hum.
