Not really; it might even be the other way around. OpenAL is a cross-
platform API that, on Mac, is implemented on top of CoreAudio. The
CoreAudio APIs have varying degrees of complexity, but most of them
are pretty low-level, i.e. you're dealing directly with buffers full
of samples and shoveling them around on background threads.
There is unfortunately nothing comparable to CoreAnimation for audio.
You get NSSound, where you can play a canned sound in one line but
can't do anything interesting with it; QTKit, which gives you
multimedia support; AudioQueue and AudioFile, where you can write
several pages of C code to load, play and record audio data; and
AudioUnits where you can write pages and pages of gnarly C++ code to
perform fancy real-time audio processing. (That's not strictly
accurate, but I think it's a fair ballpark view.)
