4.2 Noise Reduction

The NR function suppresses the stationary noises present in the far-end/downstream and near-end/upstream signals. The NR module can also effectively suppress the unwanted noise with the proprietary intelligent Voice Activity Detection (VAD), while maintaining satisfactory quality for the voice communications. This function allows both near-end and far-end users to experience the benefits.

The following figure illustrates the interface of the NR and dual MIC NR parameters in the DSP tool.
