I have a problem with pfft~. If I specify an overlap higher than 2 I modify the duration of tapin/tapout inside the pfft~.

Look this :
the “my-pfft” patch :

#P window setfont “Sans Serif” 9.;
#P window linecount 1;
#P newex 285 294 94 196617 send~ $1-my-test;
#N in 2;
#P newobj 346 119 25 196617 in 2;
#P message 346 142 98 196617 0 , 1 10 1 300 0 10;
#P newex 346 163 32 196617 line~;
#P newex 285 194 27 196617 *~;
#P newex 285 128 39 196617 noise~;
#P newex 285 222 74 196617 tapin~ 50000;
#P newex 285 258 74 196617 tapout~ 3000;
#P newex 124 246 95 196617 fftout~ 1 blackman;
#P newex 124 221 89 196617 fftin~ 1 blackman;
#P connect 0 0 1 0;
#P connect 0 1 1 1;
#P connect 4 0 5 0;
#P connect 5 0 3 0;
#P connect 3 0 2 0;
#P connect 2 0 9 0;
#P connect 6 0 5 1;
#P connect 8 0 7 0;
#P connect 7 0 6 0;
#P window clipboard copycount 10;

and the main-patch:

#P user ezdac~ 153 205 197 238 0;
#P button 362 105 15 0;
#P button 194 105 15 0;
#P window setfont “Sans Serif” 9.;
#P window linecount 1;
#P newex 232 163 101 196617 receive~ 8-my-test;
#P newex 64 163 101 196617 receive~ 2-my-test;
#P newex 232 138 140 196617 pfft~ my-pfft 1024 8 args 8;
#P newex 64 138 140 196617 pfft~ my-pfft 1024 2 args 2;
#P connect 2 0 6 0;
#P connect 3 0 6 1;
#P connect 4 0 0 1;
#P connect 5 0 1 1;
#P window clipboard copycount 7;

In the main patch, when you bang in the leftmost bang, you hear the noise after 3000ms, but with the rightmost bang, you have a duration lower than 3000ms… And the only change is the overlap.
Why ?
I need to multiply the duration by “overlap / 2″ to have a right duration…

It has to calculate twice as fast for that overlap, its like a higher
sampling rate in a poly~. Just get the overlap out of fftinfo~ and
calculate according to it…
