Abstract:	A method of detecting for activating a temporal noise shaping process in coding audio signals comprises the steps of receiving continuous audio signals; computing a perceptual entropy value of each audio signal; comparing the perceptual entropy value with a threshold according to a discriminative condition; and activating temporal noise shaping process when a corresponding result is set true.
