Bark scale equalizer design using warped filter

Bark scale (also called critical band rate in the literature) has attracted increasing attention among audio engineers as a good measurement of the frequency resolving ability of the human auditory system. The warped filter technique has been applied to the Bark scale to construct an equalizer for a low-cost loudspeaker system. In a simulation, the resulting equalizer displays an overall better equalization effect than the conventional deconvolution-based equalizer.
