Hi all,
I have a PCI device and a IOAudioDevice that handles the sound input.
Do I have to care about deviations from the nominal sample rate?
I have a deviation of 0.7 Hz (on my card in my Mac) and I have the
assumption that this leads to the sound distortions I observe. If my write
head is constantly faster than the read head something will go wrong sooner
or later.
Does the Audio HAL care for this kind of deviation? It is not stated
directly but that was my understanding of the documentation.
If it does not care for this how should I care?
With kind regards
Dirk Musfeldt
