AUGraph and output callback

Hi Everyone,

I am new to CoreAudio but I am almost done building an AUGraph that reads audio files, mixes them, adds filters and outputs to any HAL device. However, I would like to save the samples that are played out to a file using our own code (I know about Audio Hijack Pro, but I don't want our users to have to buy extra software).

So is there a way to insert a callback at the output of the graph in order to get access to the samples ? There would be no synchronization issue since we will merely save them to a file.

I have also considered writing our own audio unit and a splitter, but that seems like an overkill.

Any clues on how to solve this ?

Thanks a lot and best wishes to everyone !
