filters

I am writing an iPhone application to apply filters to audio input and output the result in real time.

I am new to audio processing but using audiounit, the correct approach?

I found out how to output data using audiounit but couldn’t figure out how to capture input audio.

Is there a sample application showing how to connect input and output using audiounit?
