State of the art on subjective assessment of spatial sound quality
Abstract
A new aim of sound technologies is spatial reproduction, which raises new questions about their quality assessment. This literature review deals with spatial audio quality: for audio coding, assessment is made through use of two mainly subjective ITU-R test methods. But, they are restricted to the evaluation of the overall quality. The finding, through various studies, of some features specific to surround sound drove us to wonder whether they can be included in a new quality assessment.
