if you build the sphere using (build-nurbs-sphere h r) then pdata-size 
will be (h + 3) * r.

if you only want to work with the horizontal segments as you did in the 
example you just make the sphere horizontal segments three less than the 
audio buffer size.

if you want to fit each element of the audio buffer to a separate nurbs 
knot, knowing the audio buffer size, and provided that h = r, this is a 
quadratic equation: x^2 + 3x = buffersize.

hope this helps.
