Check the size of your buffer. I believe that I may have run into
the same error and had to fix it by reducing my buffer size,
sometimes by looping over a larger buffer and writing smaller chunks
to ExtAudioFile. As soon as I sent in a smaller buffer, the error
stopped, and the resulting file had no problems.

I am getting an kExtAudioFileError_AsyncWriteBufferOverflow (-66570)
when using an ExtAudioFileWriteAsync from a render callback. I only
get the error when I am encoding the Audio (AAC). If i record
straight
pcm (wav) its all good. In the simulator all works fine as well. Am I
simply running out of processor power on the device (iPad)? I thought
there was a hardware encoder, is there any other considerations I
should take into account when doing this?
