Interpolation might be needed in a number of places (delay lines and playback of audio from buffers at altered speed comes to mind), so the question is what is the best DRY way of doing so. Two possible solutions are

  1. methods in Jamoma Foundation or Jamoma DSP (it's not necsessarily only audio that we might want to interpolate)
  2. Develop a Interpolation Library

There are a number of different ways of interpolating

  • linear
  • polynomial
  • spline

We will have to take into consideration that the kind of data passed to and from the interpolating operator might differ widely depending on what interpolation is used.

currently TTDelay.cpp is the place to look for our existing interpolation code
