چکیده

A calibration method allowing users to customize the loudspeaker layout for 2-, 4-, and 5.1-channel playback, and to steer the “sweet spot” to the position o f the listener’s head is presented. The method, which is applied to a computationally efficient transaural 3D audio system for dynamic spatialization o f multiple sound sources, is based on u ser interaction and auditory feedback. The robustness of the a uditory sensation is analyzed for small displacements of the listener near the sweet spot. A modification of the system permits continuous adjustment of the sweet spot size by the listener. The modification limits the a rtifacts due to the transaural processing for positions away from the sweet spot. For wide settings, the system gradually reduces to a discrete amplitude panning system.

Review of Digital Filter Design and Implementation Methods for 3-D Sound

In this paper, we discuss methods for digital filter design with application to 3-D sound. A review of existing filter design methods for binaural and transaural processing is presented. New methods that take into account the nonuniform frequency resolution of the human ear are explored. Listening tests have been performed to determine the subjective preference of different designs. 0 INTRODUCT...
