Abstract

This paper presents a new method of designing room equalization filters using a warped common acoustical pole and zero (WCAPZ) modeling. The proposed method is capable of significantly reducing the order of the equalization filters without sacrificing the filter performance. Thus, the associated input-output delay is much smaller than the conventional room equalization method while its computational complexity is comparable to it. This paper also presents an adaptive IIR filter structure to overcome computational problems associated with calculation of CAPZ coefficients. Simulation results confirm that the use of the proposed algorithm significantly improves the room equalization over a range of low frequencies.
