When trying to translate the settings of a 10 band graphic equalizer
to a smooth spectrum I had a similar issue for which I used cubic
interpolation in three steps. The first two steps involves factor 2
'upsampling' each, which renders a 40 point (+interpolation points)
curve smooth enough for interpolation to 1024 points in one last step.
Attached patch cubic_upsampling.pd shows the interpolation steps done
on a sequence of random numbers.
