For the evaluation of perceived quality in audio coding, two well-known subjective test methods, both of which are based on Basic Audio Quality (BAQ), are recommended by the International Telecommunication Union. Although a predictor of quality, BAQ is likely to be multidimensional. Listening tests can be used to evaluate other attributes that contribute to impairments created by coding. The goal of this study is to define categories of additional attributes, thereby providing a complement to the single BAQ metric. When quality attributes are sorted, there appears to be three groups: one related to space, a second related to defects, and a third split into timbre and quality.
