Description

AudioDataOutputToAudioUnit is a short sample that demonstrates how to use the QTSampleBuffer objects vended by QTKit capture's QTCaptureAudioDataOutput API with various CoreAudio APIs. The built application uses a QTCaptureSession with a QTCaptureAudioDataOutput to capture audio from the default system input device, applies an effect to that audio using a simple effect AudioUnit, and writes the modified audio to a file using the CoreAudio ExtAudioFile API.
