Ther 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 439 280 The "window size" is the total trajectory of the read +points in the delay line \, in milliseconds.
