I needed a sound of cows chewing. So i went driving around in the countryside and found some cows close to a road that were eating in a trough. I put my mic close to them while they munched away. Sometimes they licked the microphone i was so close!.
This is recorded inside a milking barn in hualian, taiwan, using a zoom h2n. The milking hours were not up, so the cows were very excited seeing us entering.
