Hello Christian,
Sorry this question got lost in the shuffle. I imagine at this point you have worked out some suitable settings?
The settings will depend a little on what the application is. For instance, a microphone for a podium used for live speaking would have different settings then audio for a radio transmitter with a cell phone sort of being in between these two extremes. So let me know if you are still working on this problem and more detail about your application. Thanks,
Dave T
