#X text 24 560 Here we apply an amplitude envelope to protect against
discontinuities at the loop point. The envelope is based on the pulse
width modulation example \, except that the widening is applied to
the "1" part of the pulse \, not the "0" part.;
#X text 23 647 To see the envelope \, put the phasor on 2 Hz \, select
"sharpness" values between 1 and 3 \, and look at "cos-input" and "cos-output."
You should both see and hear the effect of the "sharpness" parameter.
