A perceptual audio codec using Warped Linear Prediction, Temporal Noise Shaping, and Vector Quantization is presented. These techniques are used to shape the quantization noise according to spectral and temporal masking characteristics of the ear. The quantization process is controlled by an auditory model. Simulations and subjective listening test results of the codec are also presented.
