Hi Bill,

> you'd have to get the internet stream decoded to linear pcm, then feed this into a graph through a callback attached to an AU (that is represented by a node).

If I understand it correctly. I must export the audio data from Audio Queue to a Audio Unit?
Ok, an example for using AudioQueueOfflineRender with Audio Queues is very good. :)

> There is a tech note written to explain how to use the AQ in this manner.

Ok, sorry for this question: How can I find this tech note? Have you a link for me?


Thanks in advance.

Best regards
Alexander Saal
