I'm not completely sure if I understand it correctly, but if you have a
playback callback installed to play the audio, you would be able to
read the time from the parameters passed to your callback
I need to read "current play position" and "audio file length" times
from an aiff file...
How are you playing back the file; using which API/functions ?
-Are you using QuickTime or CoreAudio or something else ?
AudioDeviceGetCurrentTime seems to return null SMPTETime structure.
I think it's better to ask this question on the CoreAudio list.
