Minimum perceptual spectral distance FIR filter design

This paper addresses the problem of designing finite impulse response filters which optimally approximate desired frequency responses in the sense that they minimize a perceptual audio spectral measure. This measure is based on a simplified auditory model similar to those used in the area of perceptual audio quality measurement. It is shown that this problem can be cast as a logarithmic Chebychev approximation problem, which can be solved efficiently using interior point methods
