iPhone Sampling Rates

Hello there,

I'm pretty new to iPhone audio programming but I'm getting there. I'm using an AUGraph with a mixer and the remoteIO unit. I use the mic input to do some analyzing and then playback audio via the mixer through the remoteIO. When you enable the microphone on the iPhone2G the sampling rate switches to 8000 Hz. The iPhone 3G stays at 44100 Hz.

Does anybody know if it is possible to have the playback at 44100 Hz while the input is at 8000 Hz on the iPhone2G? This means that the remoteIO unit should have the input at 8000 Hz and the output at 44100 Hz.

What would be the way to connect them?

Thanks for any pointers.

Jorn
