might this result match what you have?
Yes! I only derived the formula for the linear ramp, p(t) = t/2,
because one can get the other shapes by warping time and I didn't want
to bloat the cumbersome equations. With the linear ramp our results
match exactly.
okay. i would still like to "hunt" for a splice displacement
around that
quiet region that would have correlation better than zero
Sometimes you are stuck with a certain displacement. Think drum loops;
changing tau would change tempo.
i think it's better to define p(t) (with the same restrictions as
o(t)) and find g(t) as a
function of r than it is to do it with o(t) and e(t).
I agree, even though the theory was quite elegant with o(t) and
e(t)...
do you have any of this in a document? i wonder if one of us should
put this down in a pdf and put it in the music-dsp "code" archive.
