#X text 425 153 This is a classic rotating-tape-head style pitch shifter
using the vd~ variable delay object. There are two moving tape heads
\, each of which is loudest at the middle of its trajectory \, and
enveloped out at the moment it has to jump back (or forward) to start
another scratch. Most of the brain work is in computing how fast the
tape heads have to move to get the desired transposition.;
#X text 425 272 The "window size" is the total trajectory of the read
points in the delay line \, in milliseconds. The delay times are controlled
by a phasor~ object. The second delay time \, 180 degrees out of phase
from the first one \, is computed using the "wrap" object.;

from the first one \, is computed using the "wrap" object.;
#X text 422 454 The cos~ objects compute the fadein and fadeout of
the two delay line outputs. They each traverse the positive half of
the cosine waveform (phase -0.25 to +0.25) over the time the phase
goes from one end to the other.;
