would be interesting to see one :)  My next project is to decompose 
complex waves into sheet music :)

FFT = Fast fourier transform

of course - thats about a month away at the rate of my current project 
:)

Hoho!

ok i upload the old demo

*** UPLOAD at http://sites.google.com/site/rebolish/Home
(see FFT.R at the end of the page)

you have to load a wav sample

Wow - first use of CP (alias of COPY) I ever saw. I override CP to 
be a unixiod file copy function.

long wave file .... crunch crunch...

it's an old script Anton

I see a little graph :)

yep, it show a graph with some frequencies, don't remember why...

:)

I've got an old script which uses FMOD library to show a spectrum 
window in rebol while a sound is playing. It's a Windows DLL but 
it works in wine.

 do-thru http://anton.wildit.net.au/rebol/audio/fmod/play-rebol-sound.r

Icarii, calculate RMS of the sound.

Anton:
** Script Error: cv has no value
** Where: do-parse
** Near: cv mold type-converter/c-to-rebol-map

Steeve, thanks for the FFT, I'm really interested. I had only DFT 
running for my modular synth. And maybe iFFT also, I don't remember, 
I hope the sources are still somewhere in deeps of the Internets.

Anton, you asked why i had an FFT implementation...

Because, i made some tests to extract frequencies from wav sounds, 
to be able to play sounds on an old 8bit sound chip.
And also, i wanted to use FFT to make an image compressor.
Geez, so much projects vanished...

Oldes, thanks. Do this

 load-thru/update http://anton.wildit.net.au/rebol/os/make-external-library-interface.r
then try again.

new version of synth almost ready - added an oscilloscope so i can 
see where my complex waves are not behaving .. lol

just realized that altme (probably rebol itself..) fucks up my system 
volume  :-(

when it pings, my sound driver's "WAVE" slider resets to 33%   >:-(

has anyone noticed this side-effect with rebol before?

it should just set its own volumn, not the system's wave volume..

ah thanks.
