Ok... so it seems that there is a lot of possibilities to implement sound on MacOS/X. What is the more flexible, fast, effective and powerful API to implement sound on a MacOS/X platform? I mean an equivalent of DirectSound, but for MacOS/X.

I'm really not sure what you're asking. I've never used DirectSound.

You are currently using the lower levels of CoreAudio to play sound. AudioUnits are slightly higher level, but I'd still consider them part of the CoreAudio API. They're not a completely separate API or anything--they were designed at the same time and share lots of things.

Contrast this with the old SoundManager or QuickTime, which are definitely separate, older APIs. On OS X, they happen to be implemented on top of CoreAudio, but you can't easily bypass the high levels and get into CoreAudio if you want.

The current state of the art on OS X is to use CoreAudio and AudioUnits.
