Noise Reduction is a fundamental task of voice band audio signal processing, wherever a microphone receives not only the desired voice signal, but also unwanted noise.

Where only one microphone is available, Single Microphone Noise-Reduction provides excellent results with stationary or slowly changing noise.

Dual-Microphone Noise-Reduction attenuates also non-stationary noise maintaining excellent voice quality. The second microphone is mounted in a way that it receives less voice, but similar noise levels.
