Perceptually Motivated Audio Equalization Using Fixed-Pole Parallel Second-Order Filters
2008
IEEE Signal Processing Letters
Preserved Fulltext
In audio, equalizer design should take into account the frequency resolution of the auditory system. In this paper, this is accomplished by the fixed-pole design of parallel secondorder filters. The design process has two steps: first, the poles of the filter are set according to the desired frequency resolution. Then, the feedforward coefficients of the second-order filters are determined by a linear least squares solution. The proposed parallel filter achieves effectively the same
