Results of a Differential Perceptual Audio Coding Technique

The differential perceptual audio coding (DPAC) technique is based on conventional perceptual audio coding methods, but utilizes the local stationariness of the signal to improve bit-rate requirements by up to 30% compared with these methods. Results (bit-rate requirements, NMR, seqm. SNR) are presented for the DPAC method applied to different audio signals, compared with the standard perceptual audio coding system.
