Figure 4From: An improved adaptive gain equalizer for noise reduction with low speech distortionIn plot a , the total gain G k ( n ) in subband k = 1 for the SBA and the proposed algorithm is shown. In plot b, the processed audio signal y k (n) in the same subband is shown for the SBA. In plot c, the processed audio signal y k (n) in the same subband is shown for the proposed algorithm.Back to article page
