Convention Paper

Bridging the Gap: Extending MPEG Audio Down to 8 kbit/s

Authors: Dietz, Martin; Herre, Jürgen; Teichmann, B.; Brandenburg, Karlheinz

AES Convention 102 · Paper 4508 · March 1997

Abstract

MPEG Audio is becoming the do-it-all system for applications in speech and audio coding, ranging from a few kbit/s to several hundred kbit/s. Originally devised for transparent coding of high-quality audio, the marketplace demands the application of the same ideas to intermediate-quality audio or even speech coding at bit rates comparable to those of classical speech coding schemes. The paper provides an overview of the recent developments of audio coding at bit rates below 64 kbit/s/ch. These include the MPEG-2 Low Sampling Frequencies mode, MPEG-2 Advanced Audio Coding (MPEG-2 AAC), and MPEG-4 Audio.
