I'm getting some really poor performance with ExtAudioFileRead
sometimes. While reading audio from a m4a with Apple Lossless in it,
it sometimes takes an extremely long time to complete the read.
Typically it takes on 0.000002 seconds to complete the read. Then out
of nowhere it takes approximate 0.4 seconds to complete the read. The
reads are for 256 samples of audio at a time. Perhaps this should be
larger?
The only thing that I can think of is disk contention, but at 0.4
seconds that seems like a long time even for disk contention.
Does anybody have any ideas why ExtAudioFileRead could be so slow?
