spectral interpolation

This patch allows us to make spectral interpolation (morphing) between two 'Spear' files;

Using 'Spear'; analyze any length of sound, reduce the content of the spectrum by deleting partials below x magnitude{dB} and x length{sec}.

After you've downloaded the  s p e c t r a l  i n t e r p o l a t i o n  f o l d e r

open ~/spectral-interpolator-help.pd

1- type 1 on the number box
2- choose the .txt 'Spear' file {departure}
3- type 2 on the number box
4- choose another .txt 'Spear' file {target}
5- send an init bang
6- start playback [you will hear the first sound character]

after these steps you can navigate between two sounds using the yellow slider.
for best results, both Spear files should have the same number of partials- & frame-count.


I used Dan Ellis' patch to import Spear files into Pd.
