Two-dimensional hybrid spatial audio systems with user variable controls of sound source attributes

Abstract

This paper presents two novel hybrid spatial audio systems demonstrated for use in two-dimensional applications with their scalability to three-dimensions. The emphasis of these hybrid systems is to give further creative freedom to a composer, sound engineer or sound designer. The systems are principally based on the end result of Ambisonics spatial audio reproduction systems. Since Ambisonics systems are used primarily for temporary sound installations and exhibits, the use of B-Format can be unnecessary. Therefore these systems revert to producing channel based content rather than sound field content that is later separately decoded. The presented systems use the decoder as a real-time sound manipulation feature on a per sound source basis. A comparison is drawn between the two systems and each method is described as to how it can be used as part of a standard music production workflow. © 2013 Springer-Verlag.
