Convention Paper

Efficient Intraframe Coding of Monophonic Audio

Authors: Ferreira, Anibal J. S.

AES Convention 116 · Paper 6166 · May 2004

Abstract

This paper describes recent developments on the design of an advanced Audio Spectral Coder (ASC) that seeks:
coding efficiency by combining source and perceptual audio coding techniques; bit stream semantic scalability
by segmenting the audio signal into transients, sinusoids and noise; low delay coding by using a moderate
transform size and no bit stream buffer; and embedded error robustness by not using interframe coding.
The operation of ASC is explained, its performance is assessed using a few test results, and potential application
areas are also addressed.
