It is not a constant sound because several alterations are perceived during its reproduction, there are moments when it is soft, strong, slow, etc. It was activated the moment a person chopped potatoes.
Chewing: crunching hard food in closed mouth, slower pace. Crunching ice or other larger, harder food. Edited from the sound of a salt grinder intermittently crushing rock salt (tempo increased 15%, high cut eq applied to simulate closed mouth). Recorded using a tascam dr-40x and processed in audacity.
This is a computer generated short sound clip. It sounds like someone with a mouthful of potato chips. It was created by modulating a few different pitch shifted sounds together.
