This library is for driving 3D speaker arrays. Picture
16 speakers arranged evenly on the surface of a large sphere with an audience
inside. Each speaker is connected to an amplifyer. This library will specify
the amplifier gains (volumes) required to perceptually place a sound source
at a particular location in space. The sound location will be farfield -
that is it will sound like it is emminating from beyond the speaker array
in some 3D direction. Sound sources may move and in real time this library
will adjust the required speaker gains. Speakers may also move and in real
time this library will adjust the required speaker gains. This is the first
library known to the author which allows the speakers to move in real time.
