kExtAudioFileError_AsyncWriteBufferOverflow on iPad

Hello All,

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?

Thanks

Aran
