Abstract
An apparatus, a circuit and a method are given, to realize very effective noise suppression for speech signals. Using thereby novel calculation methods allow for a real-time operation without any remarkable delay. Also a significant reduction of the overall processing power demands in conjunction with reduced memory requirements is achieved. Using the intrinsic advantages of that solution the circuit of the invention is manufactured with standard CMOS technology and/or standard Digital Signal Processors at low cost.
