Hello, I am quite interested in that programme. Indeed, I am more and more interested in general harmony (of nature and mind...) and its "general relativity". I am currently having a look at the link between visual arts and music. Is your programme can also translate with inverse FFT (from image to sound)? Is there the inverse transformy than PVANAL? A French guy (sorry) called Vincent Lesbros at the GAIV (Paris VIII) built a similar programme. The problem is that it only did the inverse FFT. I would really enjoy having a look at your programme. Yours, Olivier. ---------------- Olivier PASQUET - Faculty of Music - APU op101@mercury.anglia.ac.uk http://www.sinclair.anglia.ac.uk/~op101.student.cambridge.anglia -----------------
