+#X text 28 362 Here we apply an amplitude envelope to protect against
+discontinuities at the loop point. The envelope is just a cosine wave
+from -90 degrees to +90 degrees \, (-pi/2 to pi/2 radians) \, i.e.
+\, the part that is zero or positive in sign. The "cos~" object's input
+is in cycles (units of 2pi radians) so -1/4 to +1/4 addresses the desired
+part of the waveform.;

+by the tabread4~ output so that it doesn't click when the phase wraps
+around.;
