Hello Steph,
Yes, I've tried both. They all make the audio playback "glitch" and seem have no much difference. I am actually very curious how the AudioFileReadPackets and ExtAudioFileRead work. Do they make threads by themselves while reading from files? So many mysteries...

Have you tried using AudioFileReadPackets?
it seems to have better control, cache option and void* to your buffer. it also returns frames read (possible less than requested) but the docs don't mention this possibility. i suspect this is a "lower-level" call thus a bit faster for feeding a hungry callback.
i use it to load whole samples in (non-realtime) so i can't really say. could be wrong and would love to know if it is an improvement
cheers
