-#X text 154 8 RESONANT (BAND-PASS) FILTER;
-#X text 26 129 The two controls specify \, first \, the center frequency
-\, and second \, the sharpness of the filter \, commonly called "q".
-If you increase q to 10 or 20 \, you will see a drop in total signal
-power \, and moreover \, you'll see and hear the resonant frequency
-more clearly in the result.;
-#X text 28 30 A simple resonant band-pass filter is provided in the
-bp~ object. Resonant filters can be tuned to a specific "center frequency"
-and then will pass that frequency while attenuating other frequencies
-(the further from the center frequency \, the more attenuation). This
-patch uses a white noise source to demonstrate bp~.;
