Yes it would be if there was some decent documentation on all of them (mostly ALSA!).
But basically now ALSA is THE core sound system on top of which runs an emulation of OSS, and these days Pulse then uses ALSA to talk directly to the sound hardware and then it creates a fake ALSA device which apps then use. It also presents its own Pulse APIs which can be used. The there's also JACK.... RAT can talk to ALSA (Preferably without Pulse as it's not so good for realtime but it can be a mild pain to disable) or OSS. Here's a blog post (which I haven't tried) http://ptspts.blogspot.com/2010/11/how-to-disable-pulseaudio-on-ubuntu.html Unfortunately I have zero time to work on RAT these days but think the memory leak is due to the fact I forgot to comment out some of the pcm_status structure allocations and unused calls.

Its based on a slightly earlier version (as was used in Ubuntu 10.4) and does not exhibit the memory leak problem.
