We consider the warped DFT as an alternative basis for psychoacoustic models. The appropriate construction of the transform is approached, aiming for precise critical band power analysis. It is shown that sufficient spectral resolution can be obtained for sample block lengths several times shorter than the 1024 or 2048 commonly used in the FFT based ear… CONTINUE READING
