Hi Daniel,
You need to implement buffering and output silence while you don't have
enough audio samples for your FFT/IFFT transformation. It is necessary
to output the correct value for GetLatency/GetTail functions.

Does anyone know how to change the frame size when doing the digital signal processing on an audio unit? Currently my audio unit is set up so that it receives a single sample, does the signal processing, outputs the sample, and repeats the process for each sample of the audio signal. I have created quite a few audio units with this set up but now I want to process multiple samples at the same time to do the FFT/IFFT, etc. Does anyone know how to do this? It seems like most people are using audio units for iiOS, but my audio units are for OS X to be used in programs like Logic Pro. Don’t know if that makes a difference.
