Convention Paper

A New Noise Injection Model for Audio Compression Algorithms

Authors: Durot, Xavier; Rault, Jean-Bernard

AES Convention 101 · Paper 4374 · November 1996

Abstract

A new approach for noise thresholds calculation in audio coding is introduced. The proposed scheme relies on a nonuniform filterbank analysis of the signal and on energy-spreading curves inside the cochlea as objective measurement tools do. The shape of the analysis filters matches the human auditory filters, thus temporal effects are taken into account.
