sparrow + libpd

jfreymann

Hi,

I am trying to use libpd as a sound engine for a cocoa project based on sparrow. So far, the pure data patch is loading succesfully and libpd's audio is enabled. Audio/DSP is running (and audible) for about half a second and then stops. I have started the SPAudioEngine as an ambient session, but that did not help. It seems like sparrow's rendering loop is blocking libpd, is that possible?
Libpd is spawned from the Game.m class in the Demo-Project.

Did somebody already manage to run libpd alongside sparrow in one app?

Any suggestions would be helpful.

That's seems a great lib, I've never heard of it before! Thank you for it!
About your audio problem, I had the same issue a week ago when I updated my iPad to iOS 7.1 and it made me mad. I don't remember exactly how i solved it, I think I started the AV audio session manually without starting the SPAudioEngine.

Yep, libpd ( https://github.com/libpd/pd-for-ios) is awesome. I have used it in an android app and was very happy with it.

Apparently, the audio playback problem is not connected with sparrow in any way. Libpd seems to be broken on ios 7.1 🙁

ok, I was wrong again! the latest version of pd-for-ios from github is working out of the box on ios 7.1
