Hi Ron,

Check out `AUGraphAddRenderNotify` and friends in AUGraph.h. This gets called once before and once after each time the graph renders.

HTH,

Art

I have an AUGraph that consists of the following:

A DefaultOutputUnit that pulls from a AUTimePitch which pulls from a AUAudioFilePlayer.

I want to be able to adjust the start time, set start / stop limits for a loop and monitor playback position.

I'm assuming that I will do this using Frames.

This is pretty easy with an AudioQueue using the AudioQueueOutputCallback. But, I don't see this option using Units and a Graph.

Any suggestions?

Thanks - Ron
