A Quantization Method Based on Binaural Perceptual Characteristic for Interaural Level Difference
In this paper, we study the mechanism exists of perceptual redundancy in spatial parameters and remove redundancy from energy domain to parameter domain. We establish a binaural perceptual model based on frequency dependent of Interaural Level Difference(ILD) and use this model to direct quantitation of ILD. It solves the problem that the perceptual redundancy of spatial parameter is difficult to remove. The new quantization strategy merely quantizes the perceived variable quantity of ILD to reduce the coding bitrate. 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
