Abstract EN
The use of microphone arrays for sound-source localization is a well-researched topic.
The response of such sensor arrays is dependent on the quantity of microphones operating on the array.
A higher number of microphones, however, increase the computational demand, making real-time response challenging.
In this paper, we present a Filter-and-Sum based architecture and several acceleration techniques to provide accurate sound-source localization in real-time.
Experiments demonstrate how an accurate sound-source localization is obtained in a couple of milliseconds, independently of the number of microphones.
Finally, we also propose different strategies to further accelerate the sound-source localization while offering increased angular resolution.
