AFAIK there's no transform that really mimimcs our perception, i.e. which provides a visual representation similar enough to the auditory perception. Take also a look at the Stockwell transform, which is a somewhat balanced compromise between the properties of the FFT and the properties of the wavelet transform. ... BTW frequency dependent windowing and standard fractional octave smoothing aren't completely equivalent. There's instead a proven equivalence between frequency dependent windowing and *complex* smoothing. See the Mourjopoulos papers for further details.
