Install the Core Audio Development Kit

1. If you haven’t already done so, install the most recent Core Audio SDK. It is part of the Xcode Tools installation on the Mac OS X DVD. You can also download it from Apple’s developer website at this location:

   http://developer.apple.com/sdk/

   The Core Audio SDK installer places C++ superclasses, example Xcode projects, and documentation at this location on your system:

   /Developer/Examples/CoreAudio

   The SDK also installs Xcode project templates for audio units at this location on your system:

   /Library/Application Support/Apple/Developer Tools/Project Templates/

2. After you have installed the SDK, confirm that Xcode recognizes the audio unit templates, as follows:

   • Launch Xcode and then choose File > New Project.

   • In the Assistant window, confirm that there is an Audio Units group.

   Having confirmed the presence of the Audio Units template group, click Cancel, and then quit Xcode.

   Note: If there is no Audio Units template group, check whether the SDK files were indeed installed as expected. If not, try installing again. Also make sure you are using the newest version of Xcode.
