Abstract

In present mobile communication system, low bit rate audio signal is supposed to be provided with high quality. This paper researches the mechanism exists of perceptual and statistics redundancy in binaural cues and establishes a selection model by joint perceptual and statistics characteristic of ILD. It does not quantize the values of ILD where the frequency bands can’t easily be perceived by human ears according to the selection model. Experimental results showed that this method can bring down the parametric bitrate by about 15% compared with parametric stereo, while maintaining the subjective sound quality.
