#X text 111 529 Here \, rather than ask you to push the read pointer
back and forth in the sample \, we use a phasor~. This makes it possible
to avoid the samphold~ on the read pointer (r~ read-pt) \, since \,
knowing the precession \, we can correct for it in computing the frequency
of the original phasor~ at right.;
#X text 111 626 We've changed the control for "chunk size" to milliseconds
for added convenience \, and delayed multiplying sample location by
the sample rate (44100) until the last moment \, so that calculations
using "read-pt" and "chunk size" can be in the same units (seconds.)
