Cubic interpolation is most useful with sample player opcodes like loscil.
A better delay tap or vdelay.  Other than 2n+1 is needed.  If you send the
code to me I might try a cubic vdelay or deltap.

Apparently the difference can be heard, especially on samples.

Cubic seems to be more state of the art.

I think there has been some discussion on sinc interpolation as being more
efficient than polynomial interpolation although I do not know enough about
it to comment.
