Validity of Selected Spatial Attributes in the Evaluation of 5-channel Microphone Techniques

Abstract

Assessment of the spatial quality of reproduced sound is becoming more important as the number of techniques and systems affecting such quality increases. The presence of dimensions forming spatial quality has been indicated in earlier experiments by using attributes as descriptors for the dimensions. These attributes have been found relevant for describing the spatial quality of stimuli subjected to different modes of reproduction. In this paper, new attributes are elicited and the applicability of these and previously encountered attributes for assessment of spatial quality is tested in the context of new stimuli, recorded by means of 5-channel microphone techniques and reproduced through a 5.0 system.
