How do I make a AU play at a faster rate?
You need to define what you mean by that. higher sampling rate? more
samples per render? plays at a higher frequency (e.g. oscillator or
sample playback) ?
An AudioUnit lives not in isolation, but in relation to its inputs and
outputs. If you want to increase the sampling rate or buffer size, then
you are going to need to address that with whatever hardware or
software is driving you downstream (e.g. HAL, DefaultOutputUnit, or
code for nonrealtime writing to a file, etc.). There is
kAudioUnitProperty_SampleRate to set the unit's sample rate.
If you want to change a frequency then you'd do that with a parameter
defined by the AudioUnit.
