How do you mean the CoreAudio backend? I would have thought I should just be able to call the process function in my render callback. Did you check out the code I posted? I happy to provide that as an AudioController for libpd on OSX. Messages and print objects work correctly but libpd is not processing any audio.
Cheers, Joe

As far as I know, the OSX port isn't finished and the CoreAudio backend isn't hooked up. Anyone wanna help out there or sponsor us? :D

Hi guys,
Does anyone have any experience running libpd in an OS X app, using CoreAudio.
I'm able to run a patch and receive print statements but I'm not getting any audio output and DSP doesn't seem to be processing. I created a quick test tone in code to see if it was my audio unit but that works. My main problem it seems is that after calling
[PdBase processFloatWithInputBuffer:leftBuffer outputBuffer:leftBuffer ticks:ticks];
...the buffer is still empty. Anyone have any ideas?
I'm calling [PdBase computeAudio:] just before I start the AudioUnit. Here's the whole controller class if that helps: http://pastebin.com/eYf1Facp
Any help would be much appreciated!
Many thanks,
Joe
