CoreAudio PublicUtility on Xcode 4.3.1 iOS 5.1

Question

I have an application that uses low-level CoreAudio C features, usually located under /Volumes/Xcode/Xcode.app/Contents/Developer/Extras/CoreAudio/PublicUtility/. Just installed Xcode 4.3.1 and iOS 5.1, and Public Utility seems to be gone. My missing files: CADebugMacros.h CAMath.h CAStreamBasicDescription.cpp CAStreamBasicDescription.h Does anyone know if these files were deleted from this latest version or do I just need to copy files from a previous version of Xcode? CoreAudio Public Utility exists with iOS 2 (at least).

Ty!

Answer 1

Xcode 4.3 explains what the new documentation is .

Select this menu:

Xcode > Open Developer Tool > More Developer Tools... 

and download "Audio Tools for Xcode".

Answer 2

The best place to get them can be obtained directly from the Apple sample reference library.

http://developer.apple.com/library/ios/#samplecode/CoreAudioUtilityClasses/Introduction/Intro.html

Links to sample code in RefLib. also provides version history and modification information that is useful, allowing you to stay up to date if bugs are fixed with these sources.

Apple seems to be updating all its audio samples to contain all the subsets of the public utility needed for each sample, but if you want all this (and I suggest you do it when it oozes with kindness), take it from the above link.
