Convention Paper

Measurement of Audio System Imaging Performance

Authors: Clark, David

AES Convention 127 · Paper 7936 · October 2009

Abstract

Mixing engineers assign different sounds to different channels of stereo or multichannel media with the expectation that the listener will experience the intended directional aspects of the sound. For standard +/-30 degree arrangement of playback speakers and listener, this expectation is usually realized. As non-standard influences, such as listening off-centerline, are introduced, localization and other aspects of spatial rendition are degraded. This paper describes a measurement system for quantifying these degradations in common perceptual dimensions such as image direction, width, distance and stability.
