Temporal Noise Shaping, Qualtization and Coding Methods in Perceptual Audio Coding: A Tutorial Introduction

Perceptual audio coding has become an important key technology for many types of multimedia services these days. This paper provides a brief tutorial introduction into a number of issues as they arise in todayOs low bitrate audio coders. After discussing the Temporal Noise Shaping technology in the first part of this paper, the second part will focus on the large number of possible choices for the quantization and coding methods for perceptual audio coding along with examples of real-world systems using these approaches.
