Waves graphic soundshifter. Put the link mode on unlink. leave the left line as is and raise up the right line. It defaults to maximum which is an octave so just process twice if you need to. If you need the tempo to speed up then link tempo and pitch.

This is all done in the audiosuite. make sure you lower the render head and tail time from 2.0 to something like 0.1 instead or load the wave form in the plug in and plot your points by double clicking on the line.

I want to add that you can make your looped note a consolidated file;select then press, shift alt 3 on a pc. This will be the way to process it and you can export that consolidated file in to an audio editor program which should have no problem handling this.
