PDF-The Constant Q Transform Benjamin Blankertz Introduction The constant Q transform as

Like the Fourier transform a constant Q transform is a bank of 57356lters but in contrast to the former it has geometrically spaced center frequencies 0 where dictates the number of 57356lters per octave To make the 57356lter domains adjectant one.
