Oh, I should also mention that there is an example project in the SDK
as well - both one for OpenAL and one just using the 3DMixer directly.

Hi,
I am new to the list, just joined today. I like to do hobby
audio development as an addition to music creation and performance...
I have a question, the docs are kind of thin when it comes to
which mixer one should choose to use in an application.
There are three flavors:
kAudioUnitSubType_StereoMixer = 'smxr',
kAudioUnitSubType_3DMixer = '3dmx',
kAudioUnitSubType_MatrixMixer = 'mxmx',
Could someone use the 3dMixer as a mixing board for producing
music? You know having several streams feeding into and mixing
them in 3d? I'd like to make a sample player that could feed
several sounds into it and mix them in 3d while DJing...
Yes - aside from all of its bells and whistles, it is still a mixer.
I tried setting up a prototype but could not set the Mixer's ASDB
Input to deal with floats. Do I need a format converter to use
this? I had Float32's which playback at half speed for some
reason, something is obviously coded wrong on my end.
It takes mono or stereo (deinterleaved) as an input (as well as a 4
channel WXYZ stream)... Use the CAStreamBasicDescription class in
PublicUtility as a helper for setting this up. Also, the source for
OpenAL's X implementation (openal.org) is available - it uses the
3DMixer and I'm sure this would be helpful for you
