This paper describes an experiment that aimed to identify independent perceptual attributes detailing the distortions introduced by low bit rate multichannel audio codecs. This study consisted of a verbal elicitation experiment in which the Repertory Grid Technique (RGT) method was employed. Four attributes were identified and labelled. The independent perceptual attributes uncovered were: ‘coding and high frequency noise’, ‘spatial image clarity’, ‘scene width’, and ‘tone colour’. The overall importance of each of the independent perceptual attributes identified was quantified. It was found that ‘coding and high frequency noise’ was the attribute with the highest overall importance, followed by ‘spatial image clarity’, ‘scene width’ and ‘tone colour’.
