Convention Paper

A Disk-Based System for the Subjective Assessment of High-Qualtity Audio

Authors: Beaton, Richard J.; Wong, Peter

AES Convention 94 · Paper 3497 · March 1993

Abstract

This paper describes the design of a digital system which integrates automated tandem recording with a playback system implementing an enhanced ABC triple stimulus with hidden reference listening test methodology. This methodology was developed specifically for CCIR evaluations of nearly transparent low bit-rate audio coding algorithms. The system was used extensively in recent CCIR TG 10/2 testing of low bit-rate audio coding algorithms for digital audio broadcast. The use of a disk-based system was instrumental in producing reliable assessments for the high-quality systems under test. This paper outlines the technical challenges to implementing the assessment methodology and discusses some of the important new issues arising in evaluating the quality of nearly transparent audio processes.
