Chapter 11

A Music Coder

11.1. Introduction

The program presented in this chapter simulates the MPEG-1 Layer-1 coder with a music signal sampled at 44.1 kHz at a bit rate between 64 and 96 kb/s. The quantization tables provided are only for this specific sampling frequency and bit rate range. In contrast with the program for the speech coder simulation, the program in this chapter does indeed construct an intermediate file containing the code words. However, the exact syntax given in the standardization document is not observed in this program.
