Abstract
A noise suppressor is provided which includes a signal to noise ration (SNR) determiner, a channel gain determiner, a gain smoother and a multiplier. The SNR determiner determines the SNR per channel of the input signal. The channel gain determiner determines a channel gain .gamma..sub.ch (i) per the ith channel. The gain smoother produces a smoothed gain .gamma..sub.ch (i,m) per the ith channel and the multiplier multiplies each channel of the input signal by its associated smoothed gain .gamma..sub.ch (i,m).
