i've also only read about the complexity of OpenAL, which i assume is even more low level in the sense that CoreAudio to OpenAL it's anologous to CoreAnimation to OpenGL.
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.)
