Hi
I have ported a musical instrument tuner application from windows.
I have two queries concerning audio units:
I have set up microphone input using the AUHal audio unit in
accordance with Technical Note TN2091, which works fine. However I
would like to increase the
kAudioUnitProperty_MaximumFramesPerSlice from the default value. I
have done this, using AudioUnitSetProperty(), but the
AURenderCallback parameter inNumberFrames is always the default
value. Is this the expected behaviour, or am I missing something?
I would like to set up a chain of audio units, an AUHal unit, a
format converter, and a low pass filter. I have tried setting up a
chain both using the audio unit api, and the AUGraph api. In both
cases, I can't get the rendering callback to work. Again is this
expected, or am I missing something?
Thanks in advance
Bill Farmer
