Hello Andrew,

usually, yes. 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.
