Convention Paper

Evaluating Digital Audio Artifacts with PEAQ

Authors: Benjamin, Eric

AES Convention 113 · Paper 5711 · October 2002

Abstract

Portions of the digital audio chain have been incrementally improved by development, such that objective specifications indicate a very high level of performance. Subjective reviews of these components often claim to observe substantial differences between products. This investigation uses the tool PEAQ (Perceptual Evaluation of Audio Quality) to measure the audio degradation caused by Analog to Digital Converters, Digital to Analog Converters, and Sample Rate Conversion, and also to measure the minute incremental changes of codec audio quality which accompany very small changes in data rate.
