Strategies to Increase the Applicability of Methods for Objective Assessment of Audio Quality

Authors: Garcia Arnal Barbedo, Jayme; Lopes, Amauri

AES Convention 116 · Paper 6080 · May 2004

Abstract

The current ITU?s standard for objective assessment of audio quality, Perceptual Evaluation of Audio Quality (PEAQ), has some shortcomings that prevent its reliable use for a number of codification conditions and some kind of signals. The paper aims to improve the PEAQ performance through the following proposals: 1- modifications in the manner the signals are submitted to the assessment; 2- improvement of existing Model Output Variables (MOVs); 3- creation of new MOVs; 4- determination of a better architecture for the neural network that maps the MOVs into a single estimate for the subjective score. The results are compared to those ones achieved by PEAQ.
