# openal can:
# - use __atomic_*() intrinsics when available
# - otherwise use __sync_*() intrinsics when available. It needs the
# 4-byte ones on 32 bits architectures, and the 4-byte and 8-byte
# one on 64 bits architecture
# - it also provides its one implementation of atomic operations on
# x86 and x86_64, but we dont take those into account since in most
# situations __atomic_*() or __sync_*() will be available, and not
# all x86 CPUs provide the necessary assembly instructions.

OpenAL provides capabilities for playing audio in a virtual
3D environment. Distance attenuation, doppler shift, and
directional sound emitters are among the features handled by
the API.
