Spatial Sound Reproduction with Directional Audio Coding

Document Thumbnail

[Engineering Report] Directional audio coding (DirAC) is a method for spatial sound representation, applicable for different sound reproduction systems. In the analysis part the diffuseness and direction of arrival of sound are estimated in a single location depending on time and frequency. In the synthesis part microphone signals are first divided into nondiffuse and diffuse parts, and are then reproduced using different strategies. DirAC is developed from an existing technology for impulse response reproduction, spatial impulse response rendering (SIRR), and implementations of DirAC for different applications are described.
