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

The first part of this tutorial features an introduction to the Temporal Noise Shaping (TNS) approach, including its background, time-frequency interpretation, and interaction with the filter bank. The second part addresses the issues of quantization, noiseless coding, and combined methods used in perceptual audio coders. Both variable and constant-rate coding scenarios will be discussed.
