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 ch(i) per the ith channel. The gain smoother produces a smoothed gain +E,ovs gamma ch(i,m)+EE per the ith channel and the multiplier multiplies each channel of the input signal by its associated smoothed gain +E,ovs gamma ch(i,m)+EE .
