You can get the Ben Saylor pvoc~ external at http://www.puredata.org/Members/bensaylor/pvoc%7E-0.2.tar.gz/view? searchterm=pvoc

would this work for stretching the length of a sample without changing pitch? (maybe this is the standard algorithm, I don't know)
This is either done with FFT or with granulation. [synchgrain~] or my Particle Chamber abstraction can be used for that if granulation is the technique. Abelton Live uses the same idea of making small enveloped grains and time stretching by overlapping the playback of these grains...in fact this is the most common way of doing this technique. FFT is more complicated because each grain is analyzed for its spectral content and then resynthesized.

there's also the pvoc~ external by ben saylor. it used to be here http://www.macalester.edu/~bsaylor/pvoc~-0.1.tar.gz , but seems to be gone.
