摘要：The ERIC (Energy Ramp In Critical-band) criterion for window switching in perceptual audio coding Is proposed in this paper, This new criterion can distinguish the real burst signal from the stationary signals with high perceptual entropy effectively. Therefore, comparing with the Perceptual Entropy criterion used in the MPEG standard, the possibility of misjudgment of the window types is reduced by using the proposed criterion. It results in some improvements both on the audio quality and the coding efficiency.
