To clatify: I bought the DSP board from Phoenix Audio and not the PCI-Card. I assembled it in a case which I bought at a online-shop which offers stuff for electronic devices, and small electrinic parts (e.g. transistors, resistors, etc.)
So far it worked quit well, however it needs a second to adapt to changed audio levels, for example if you drastically change distance between the mic and the speakers or change the volume of the speakers. As I still got some e-mails refering to teh ClearOne AccuMic PC, I want to mention again: This microphone is no longer being produced by ClearOne according to our German reseller for ClearOne products.
