AB  - This paper presents an efficient loudspeaker equalization algorithm combining a novel filter optimization method with a psychoacoustic model. The equalizer topology is based on a chain of second order sections where each one is a conventional parametric IIR audio filter. A psychoacoustic model based on the detection of peaks and holes in the frequency response has been employed to determine which ones need to be equalized. Using this psychoacoustic model the order of the filter could be reduced without noticeable subjective effect. The first computed filter sections are the ones that provide more correction on the response, allowing scalable solutions when hardware limitations or different degree of correction are needed. The method has been validated in the laboratory with subjective testing.
