Directional Audio Coding in Spatial Sound Reproduction and Stereo Upmixing 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.

Abstract. This chapter presents a Matlab implementation of stream-based virtual microphone directional audio coding (DirAC). It describes how to use first-order DirAC in different applications with different theoretical and practical microphone setups for both loudspeaker and headphone playback. The system performs well if the recorded spatial sound matches the implicit …
