Hello,
do please bear with my probably completely dumb question, but I spend
lotta time with the documentation and sample code without being able
to find the answer.
I've got an application which, among others, produces sound -- through
lots and lots of services, from the old-fashionated NSBeep through
QTMovies playing to NSSpeechSynthesizer output. Now, I need to process
them all using CoreAudio.
I know how to create a graph of audio units which (probably, far as I
can say without testing) do exactly what I need with the audio.
I also know how to attach the graph to the desired output device
configuring its last node kAudioOutputUnitProperty_CurrentDevice
property.
What I can't solve though is how to make this graph to stand as the
"default output" of all the sound producing services of my application
instead of the default output device?
Thanks a big lot,
---
