Estimation of the room geometry from spatial room impulse responses is studied. An algorithm for estimating the geometry is presented. The algorithm does not require any a priori information on the room shape, number of walls, or order of the reflections, but deduces the set of planes that explain the measured source and image-source locations and covariances iteratively. The algorithm is demonstrated with real data experiments.
