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.
