AB  - This paper describes an effective and fast solution for estimating speaker direction of arrival in 3D space. The main idea is to use noise as an excitation signal for sources and to determine time of arrivals from recordings of 3D space distributed microphones. Up-sampling and interpolation are applied to improve times of arrivals estimation, which are then used to construct sinusoidal signals. Sine phases are determined from times of arrival estimations and the frequency is optimised from the physical sensors’ structure. Hence, speaker direction are predicted by beamforming and direction of arrival algorithms with a precision of two degrees in azimuth and five in elevation.
