I'd like to record the system audio, on 10.4 and 10.5
Looking at other apps that do this, they commonly seem to install
a kernel extension which create a pseudo audio device.
Is this approach documented anywhere in the sample code or docs?
It seems to be common enough to qualify as an idiom, but I can't
seem to uncover any direct references to it.
Any pointers will be gratefully received ...

There really aren't any docs about doing what you want to do. The
system doesn't really make it particularly easy. Even using a fake
device has it's drawbacks (see some of my recent posts). At any
rate, the closest we have for sample code in this area are the two
sample drivers in /Developer/Examples/CoreAudio/HAL. The sample
kernel audio driver is the AudioReflectorDriver project. The sample
user-land audio driver is the SampleHardwarePlugIn project.
