A Comparative Approach to Sound Localization Within a 3-D Sound Field

Document Thumbnail

In this paper we compare different methods for sound localisation around and within a 3D sound field. The first objective is to determine which form of panning is consistently preferred for panning sources around the speaker array. The second objective and main focus of the paper is localising sources within the speaker array. We seek to determine if the sound sources can be located without movement or a secondary reference source. The authors compare various techniques based on ambisonics, vector base amplitude panning and time delay based panning. We report on subjective listening tests that show which method of panning is preferred by listeners, and rate the success of panning within a 3D speaker array.
