We are developing an application that for various reasons needs to
always work by a buffer delay: in the CoreAudio IO callback, we read
and use the current input audio buffers, but we write the result of
audio computation done the *previous* cycle in the output audio
buffers. Thus the global latency has one more buffer delay compared to
a version that would read/write audio buffers received in the IO.
It there any way to keep this one buffer delay functioning mode but
still try to reduce the I/O latency? For example "changing" the value
of kAudioDevicePropertySafetyOffset/kAudioDevicePropertyLatency
properties?
Thanks
