The use of linear microphone array composed of two closely spaced omnidirectional microphones as input to teleconference application of Directional Audio Coding (DirAC) is presented. DirAC is a method for spatial sound processing, where the direction of the arrival of sound and diffuseness are analyzed, and used for different purposes in reproduction. Two-dimensional plane arrays have been used so far to generate input signals for DirAC, in which case it is possible to measure directly two-dimensional sound field. In this study, one-dimensional linear array is used to provide input signals for one-dimensional direction and diffuseness analysis in DirAC. Listening tests are conducted to evaluate the intelligibility of speech with two simultaneous talkers, when the linear array is used in teleconference application.
