W-10 Objective Audio Quality Measurements

Chair: John Beerends, KPN Research, The Netherlands

Richard Cabot (Audio Precision, USA)
Mike Hollier (British Telecom, UK)
Michael Keyhl (Opticom, Germany)
Brian Moore (Cambridge University, UK)

In the last decades new signal processing techniques made classical measurement techniques like frequency response and signal-to-noise ratio less valuable for assessing the quality of audio devices. New test signals and perceptual measurement techniques are being developed to assess audio quality. This workshop will give an overview of these new methods, including the ones that are standardized by the ITU, PEAQ (ITU-R recommendation BS.1387) for assessing audio quality in general (music signals) and PESQ (ITU-T recommendation P.862) for assessing speech quality.
