Based on the sparcity of sounds, this paper proposes a frame-wise DOA (direction of arrival) estimation
of a target sound source in the direction of the range of ± 30° from the front of two microphones: First, the
mixtures observed at the microphones are transformed at each frame to complex spectra by short-time discrete
Fourier transform. Then, based on their phase difference, local DOAs are calculated for obtaining a distribution
of these DOAs at each frame. Next, the distribution is evaluated by a sparsity measure and, the frame with the
evaluate value over a certain threshold is judged as a single-source frame. Finally, for the distribution, its peak is
searched and the angle taking the peak value is adopted as the DOA estimate. Several experiments were carried
out to verify our proposed DOA estimation. It has been found that the proposed estimation is valid for the true
DOA being -30° to 30° under the condition where SNR>= 20[dB] and RT60 <= 200[msec]. |
