MPEG Audio Compression Basics

Chapter

Abstract

MPEG Audio was the first international standard for high quality audio coding and it opened the doors to a variety of applications in the world of digital music. In this chapter we review the basic ideas and features behind the general purpose, perceptual audio coders specified in the MPEG-1 and MPEG-2 audio standards which include the MP3 and AAC formats. The widely successful MP3 and AAC coders represent some of the most remarkable achievements of the MPEG committee that highly influenced not only the technology but also largely enabled different ways of digital media consumption.
