On the Robustness of Room Impulse Response Reshaping

Tiemin Mei, Alfred Mertins


In room impulse response (RIR) equalization and reshaping, one of the difficulties is the spatial robustness, because RIRs are very sensitive to the movements of both the signal source and the receiver. For example, the reshaping filter designed for one pair of loudspeaker/receiver or source/microphone positions will be ineffective for another pair. In this paper, we concentrate on loudspreaker/receiver pairs and propose a novel approach in which we use multiple prefilters to reshape simultaneously the RIR samples in a given area of interest (listening area). According to the RIR sampling principle, we prove statistically that the listening area will be reshaped if only the RIR samples in this area are reshaped. In simulations, we show that the proposed approach is valid.
