Nice work. There's a lot of good sounds in here, and I appreciate the effort to package them up into an asset bundle and release this as CC-BY.
It's a good test case for the modified random sound from asset bundle script I've been working on, primarily to support triggering by folder, for more control over the randomness without needing a ton of specialized plugin instances. It's fun and easy now to just tell it to "play a 'gawk'" or "play a 'breath'".
