ROOM REFLECTORS ESTIMATION FROM SOUND BY GREEDY ITERATIVE APPROACH

Marco Crocco, Andrea Trucco, Alessio Del Bue

Abstract

Room reconstruction from sound is the problem of estimating indoor space boundaries given only a set of sound events acquired by an array of microphones. In order to find a solution in realistic scenarios, it is necessary a robust and practical method that can solve the echo labelling problem, i.e. assigning at each signal delay the correct reflector that has generated it. Although being an NP-hard problem, in this paper we demonstrate that it is possible to solve the echo labelling problem in a reasonable computational time without the need of additional hypotheses on the echoes order of arrival.
