Creating a Universal Graphical Assessment Language for Describing and Evaluating Spatial Attributes of Reproduced Audio Events
AES Convention 115 · Paper 5907 · October 2003
Abstract
A Graphical Assessment Language (GAL) appears to provide the listener with a medium for describing the perceived spatial attributes of a reproduced audio event. Previous language development investigations have concluded that these spatial characteristics may be represented consistently by listeners using their own graphical descriptors. However, the ease with which these individual descriptors could be misinterpreted by a researcher was highlighted in a subsequent study; a notable problem since a primary aim of the GAL is to maintain the validity of the listener's original experience. To reduce potential ambiguities in interpretation, this investigation considers the development of a common descriptive language, consolidating listener's individual descriptors into a universal set of graphical terms identified as being effective for describing the experiences of all investigation participants. The process and outcome of creating a "universal" GAL is described.
