* More work on framing, interpolation and scaling for longer window than FFT size.

Browse Source 
This adds the --smoothing option to the command line tool and SmoothingOn/Off
  options to the API, introducing a double-length window with presum FFT and
  time-domain smoothing.  Behaviour elsewhere _should_ be unchanged.
