AES Conference: 17th International Conference: High-Quality Audio Coding · Paper 17-026 · September 1999

Abstract

The paper presents a detailed description of the EZK algorithm, a version of zerotree quantization developed by the authors, and describes why it provides higher compression than the alternatives. The performance of the algorithm using several alternative transforms is compared, and the incorporation of psychoacoustic modeling is described. Finally, the performance of the codec with some alternatives is compared.
