AB  - Directional Audio Coding (DirAC) is a spatial-sound processing technique, where the arrival direction and diffuseness of sound are analyzed in frequency-bands from microphone signals, transmitted with one or multiple audio channels, and utilized for various purposes in synthesis. Among other applications, DirAC has been used in low bit-rate teleconferencing to provide spatial separation of remote talkers corresponding to reality. Here, the use of different microphone configurations, consisting of omnidirectional or directional microphones, is discussed in DirAC teleconferencing. The audio quality with different microphone techniques for DirAC teleconferencing is evaluated by the subjective listening tests, and the results are presented in this paper.
