Does anyone know of a library of crowd hits and sounds like an arena of claps or "Heys!"

 

Look into any sample packs where they sampled a church choir, might be just what you're looking for. I don't know anything off the top of my head but maybe another member can help hone in on something exact.

 

if you're looking for single samples, you might want to check

Spectrasonics Vocal Planet- Gospel.Has what you need.Good luck.

 

Try downloading Authentic Sound Effects, Volume 4, which is the collection I usually use. There's a lot of great crowd effects, but it's probably a good idea to mix a few of them to make it sound unique (and to control the crowd 'dynamics" with different volume changes for different parts).
