Hi Anders,
If I recall Juan Pampin's ATS [1] would do what you are describing.
Lisp version was good but I have not used it in fifteen years (CMUCL)
and not so sure it will work on SBCL. Meaning that it would probably
need some toggling, if someone has some free time.
Juan and Pablo de Liscia also had some C++ binaries that worked
'realtime' but have not tried them recently. They might need
recompilatation.
If you get ATS working I'm positive you'll get what you want.

I want to remove as much-as-possible harmonic content from sound
input, leaving only the noise part. Think acoustic guitar, or
close-miked piano, leaving the 'mechanics' only.
Ultimately i'll need a real-time solution.
Perhaps something like a LPC-based approach which may be used in
real-time?
Or perhaps trying to subtract a certain part of the result of a
FFT-analysis? Or some other approach? Anyone tried?
All suggestions or refs are very welcome! :-)
