Abstract :
This paper presents a method for sound source direction estimation called Energetic analysis method, and studies the influence of the localization of the signal in the time and the frequency domains on the accuracy of this method. The resolution in time-frequency domain differs depending on the used transform. Different transforms are used in this paper, namely short-time Fourier transform, zero-padding STFT, and Gabor transform.
