This video is an adequate representation of the horrors of compressors, electric motors, and other sources of noise while recording dialog on set.
This is the sound a refrigerator makes. In person, it doesn't sound so bad. But separated from its environment, it's easy to tell what a horrible sound it realy is.
You can hear the dialog, right? I bet you can even make out words.
If I were to clean up this refrigerator noise, you'll be losing parts of your dialog... including the parts that make speech understandable.
Leave it alone = distracting refrigerator noise
Remove refrigerator = removing critical speech
So please shut off A/C, refrigerators, generators, and compressors of all types while rolling whenever practical.
Your Sound Guys
