upsampling example

The audio device in my TiPowerbook 'only' supports stereo 44100Hz output. As
I understand it I have to do the upsampling myself if I want to play an
8000Hz signal. Are there any code samples how this can be done in the
appIOProc of CoreAudio. I now do a linear interpolation between samples but
this sounds a little strange. Or maybe I should use a higher level API that
supports upsampling?

Albert.
