Directional audio coding (DirAC) is a method for spatial sound representation, applicable to arbitrary audio reproduction methods. In the analysis part, the diffuseness and direction of arrival of sound is estimated in a single point depending on time and frequency. In the synthesis part, microphone signals are first divided into non-diffuse and diffuse parts, and are then reproduced using different strategies. In this paper, the applications of DirAC to reproduce recorded B-format sound and to upmix stereo in multi-channel listening are described.
