HAL, AU or streams?

I've been reading up on CoreAudio, and I've got some confusion in my head around what level of the API is appropriate for me to use.

I wish to record sound into buffers, and playback sound from buffers. Almost always, the default input and output device will be used.

At some points in reading the documentation, I feel like it's best to access the device at the device level. Other times it appears AU's are the way to go. Finally, streams always seem interesting, but I'm not sure exactly where they fit in.

Can someone give me some basic guidance?

Additionally, if someone knows of a simple example that records and plays back sound, a pointer to it would be most appreciated.

Wade
