So how does Core handle them? This chapter digs down to a more detailed level to see how Core Audio models and processes digital audio data. We’ll start with the issue of representing sample data and formats in Core Audio’s various data structures, and then turn our attention to the APIs that can do interesting stuff with those structures. The ASBD is critically important to just about any Core Audio program, so let’s take a deeper look at it. 1, this C structure contains metadata describing the packet’s data layout: the sample rate, the number of bits in a channel, the number of channels in a frame, and so on.

By combining these opaque types with consistent naming conventions for functions, Core Foundation provides a highly manageable C API with a clarity similar to what you’re used to in Cocoa. Core Audio is highly similar in its design. Many of its most important objects (such as audio queues and audio files) are treated as opaque objects that you hand to predictably named functions, such as AudioQueueStart() or AudioFileOpenURL(). It’s not explicitly built atop Core Foundation—an AudioQueueRef is not technically a CF opaque type; however, it does make use of CF’s most important objects, such as CFStringRef and CFURLRef, which can be trivially cast to and from NSStrings and NSURLs in your Cocoa code.

You also need to add the framework to your project. Click the project icon in Xcode’s file navigator, select the CAMetadata target, and click the Build Phases tab. Expand the Link Binaries with Libraries section and click the + button to add a new library to be linked at build time. 1. You can either open the Terminal and navigate to the project’s build directory or supply an argument with Xcode. Let’s do the latter: From the Scheme pop-up menu, select Edit Scheme. Select the Run CAMetadata item and click the Arguments tab.
