Hi,
I'm finally making the migration over the CoreAudio, but have some
questions.
1) Looking at the samples it seems like most of the data which core audio
want is in float datatype.
2) Looking at the Audio HAL sample, it shows device break down on what your
sound hardware can do. I can see that my sound hardware can take 16bit sound
data.
3) Continuing on this though can you provide your sound data in the format
which best matches your sound hardware, as this limits the amount of
conversions required.
4) If you must work in floats is there going to be much over head converting
my sound data to floats and then CoreAudio converting back to a hardware
compatible format.
5) Does any of this depend on hardware and a minimum MacOS-X version to work
smoothly.
6) What gotcha's should I look out for, as I need my code to track where in
the sound buffer my playback is, as my buffers get fed into while sound is
being pulled out else where in the buffer.
Thanks in advance
Mark.
