Convention Paper

Experimenting MPEG-2 AAC Inter- and Intraframe Spectral Prediction Tools

Authors: Pena, Antonio S.; Souto, Salvador

AES Convention 108 · Paper 5079 · February 2000

Abstract

Inter- and intraframe prediction tools used in the MPEG AAC coder have been taken out of the unit and are now independent modules. Noise injection has been simulated by a truncating function that provides a signal-dependent noise power. The behavior of both tools, either alone or combined, has been tested using a database containing synthetic and natural audio items.
