Core Audio is a low-levelAPI for dealing with sound inApple'smacOS andiOSoperating systems. It includes an implementation of the cross-platformOpenAL.[1]

Apple'sCore Audio documentation states that "in creating this new architecture on Mac OS X, Apple's objective in the audio space has been twofold. The primary goal is to deliver a high-quality, superior audio experience forMacintosh users. The second objective reflects a shift in emphasis from developers having to establish their own audio andMIDI protocols in their applications to Apple moving ahead to assume responsibility for these services on the Macintosh platform."[2]
