hi,
i've reworked a little bit on sonograph~, added resize capability and a silly transformation which flips the frequencies.
the new release is available @ : http://ydegoyon.free.fr
the changes are minor and the real object of this mail is a request for finding litterature about fft's morphing algorithms. the goal is to implement these algorithms to provide new transformations to sonograph~.
any hints welcome.
cheers,
yves/
