Abstract
Energy and frequency play important roles in the scalable priority assignment schemes of scalable audio coding. Both of them should be taken into account to ensure the real important frequency subbands to be coded firstly and finely. An enhanced perceptual frequency subbands priority based scalable audio coding scheme is proposed in the frequency subbands priority assignment. The perceptual characters of human auditory sensory system are applied to prioritize the coding of frequency subbands those are more sensitive to human auditory system. Experimental results of CMOS verified the performance of proposed scalable audio coding.
