OPAQUE — A Tool for the Elicitation and Grading of Audio Quality Attributes

Document Thumbnail

The evaluation of different aspects of audio quality can be realised by means of attribute scales. Studies have shown that the attributes selected are of great importance for the evaluation result. Consequently, the process whereby these attributes are generated has to be given careful consideration. It was previously shown that elements from the repertory grid technique facilitated the elicitation and grading of quality attributes, which resulted in a new audio quality evaluation method. The result from this work has now been implemented as a software prototype aimed to support listening tests. This paper reports on the results from a pilot experiment involving the OPAQUE software.
