CAudioBuffer
Encapsulates a memory area of arbitrary length.
This is used as the primary data-transfer object
between mixers, channels, waves, and wave pointers.

Note that CAudioBuffer does NOT own the memory that
it encapsulates. This is because the memory is
likely to be some portion of a hardware-accelerated
system buffer.
