At a configurable filter bank, commands or command signals are received from an external processing device. The commands or command signals are effective to configure and connect selective ones of the plurality of elements in the filter bank. An acoustic signal is received from a transducer. The acoustic signal is converted to a PDM signal and the PDM signal is converted to a PCM signal.
