Hi Rich,

Do you want to to vary speed as well as pitch, or *only* the pitch?

As you probably know it's a lot easier to find algos that sound good doing
varispeed (both in lockstep) than one or the other alone (ie, time
stretching without altering pitch or vice versa)...

If you can live with varispeed, the package I use (Samplitude) has a great
mode in which you can grab sound clips and stretch/compress them directly
in the multitrack editing view, even be listening back to find a good
sweet spot as you do... ie, it's all realtime processing, not offline...

I say varispeed as the individual time/pitch stetching is I believe
limited to 2 octaves up/down.... :/

 best,
  aaron
