The Relationship between Basic Audio Quality and Selected Artefacts in Perceptual Audio Codecs - Part II: Validation Experiment

A pilot study [1] was conducted to investigate the perceptual importance of selected audio coding artefacts and their relationship with basic audio quality. An additional experiment was undertaken to validate the results obtained in the pilot calibration experiment. A listening test was designed which required a panel of expert subjects to evaluate the selected artefacts used in the initial study. In this second experiment however, certain experimental parameters were modified; these included different levels of degradation and programme material. The outcomes of the validation experiment are presented in this paper along with a detailed evaluation of the impact of the chosen experimental artefacts on basic audio quality assessments for perceptual audio codecs.
