OOSoundSourcePool.h

Manages a fixed number of sound sources and distributes sounds between them.
Each sound has a priority and an expiry time. When a new sound is played, it
replaces (if possible) a sound of lower priority that has expired, a sound of
the same priority that has expired, or a sound of lower priority that has not
expired.

All sounds are specified by customsounds.plist key.
