| Hi,
At the tail end of WWDC 2014 session 501, Doug Wyatt mentions in passing that these new classes can be integrated into existing core audio code. Has anyone found any examples/ documentation on how to accomplish this?
iOS 8 has broken the audio output of my audiograph code. I assume its has something to do with the deprecated audiosampletype and audiounitsampletype. On Mac OS I’ve changed these references to Float 32 and everything works as expected. For iOS 7 and earlier float 32 resulted in dangerous full volume white noise output. I found that Sint 32 worked, but apparently not for iOS8.
The developer session states that there is now a common audio format between OS X and iOS, so hopefully Float 32 with the same flags I’m using for Mac will solve the iOS 8 problem, but will require more branching code to continue to support iOS 6 - 7.
thanks,
rob
