You should have a look at the PlayBufferedSoundFile example from Kurt
Revis. It's a rather simple and well done way of understanding what you
want to do. Please note it does NOT use the Audio File API but QT for
decoding. My take would be to use the Audio File now that it's available
because it's MUCH MUCH easierthanQT and better supports some formats.
But the overall structure is the same : a realtime thread that the HAL
calls when it needs a new buffer to send to the audio interface and
another thread that reads in the file and buffers data for the realtime
thread.

I suggest this instead of the apple examples because although they are
well done, the play audio file examples are not really easy to grasp for
beginners imho ("easy to read by beginners" and "easy to maintain and
extend" are sometimes opposite goals :-).

Subject: How to begin with Core Audio?
I now have the Audio Units Documentation in my hand. And I want to make
a
very simple app that opens a audio file and just plays it out of my Motu
828
(or the built in audio device). But I don't know where to start. Can
someone
please give me some guidelines because CoreAudio is new to me. And when
I
look at the examples I still don't understand how to begin. Yes, I am a
newbee :-)
Best regards Peter
