hi all,
is there an object/abstraction/external to calculate the constant-q
transform ?
the constant q transform is basically a fourier transform, but with
logarithmic
frequency distribution.
i found some weeks ago a paper about it, written by j. c. brown and m.
s. puckette.

(djvu reader: http://www.djvuzone.org/download/index.html )
and as mr. puckette is the inventor of pd its likely that there is
something around ...
greets,
tebjan
