Is there a comparison of different algorithms and how they work anywhere? I only know of two, and I'd really like to understand them better. The two I know of are Paulstretch (which is really only for super-duper-long stretching) and Lent 1989 ("An Efficient Method for Pitch Shifting Digital Sampled Sounds"), which can be thought of as a form of granular synthesis but isn't really what most people think of when they hear that term.
