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 …

Directional Audio Coding (DirAC) has been an active research topic at Aalto University since 2007 [1]. The method operates by estimating spatial parameters to describe the input sound scene over time and frequency, which are then used to conduct the mapping of the input Ambisonic signals to the output loudspeaker/binaural channels in an adaptive and informed manner.
Binaural Reproduction for Directional Audio Coding
http://lib.tkk.fi/Dipl/2008/urn012250.pdf
A recently proposed method for storing and reproducing spatial sound is Directional Audio Coding (DirAC) [1]. It is currently implemented for loudspeakers. In this thesis it is investigated if DirAC could be implemented for headphone listening. The ultimate goal is that one can record and store sound in some space and later, using head-
