Intermediate representation for music analysis

[Ilya Sedelnikov <ilyas@xxxxxxxxxxxxxx>]

Dear list,

Does someone aware of works that use filterbanks with more than a couple of
dosens filters as a front-end for the music analysis ?

Human ear is able to distinguish pitch differences at least twice less than a
semitone which implies that for the analysis of musical piece that spans 4
octaves the number of filters should be of the order of couple hundreds.
Nevertheless front-ends commonly used for music analysis usually use not more
than couple of dosens of filters (Fourier bins), sometimes even
non-logarithmically spaced.

I will be glad to hear any opinions on the subject.
Ilya
