comparison audioio/PhaseVocoderTimeStretcher.h @ 25:e74f508db18c

* Add setRatio method to the time stretcher, and make it possible to change
  the ratio without having to construct and replace the time stretcher.  This
  means we can do it seamlessly.  Add a lot more ratios to the
  time stretch control in the main window
