I've seen a lot of people commenting about the artifacts you hear when the samples are stretched. These happen because of phasing issues, where frequencies in each of the grains are interfering with one another. I'm surprised I don't see it mentioned here, but there's a rather interesting extension to this technique made by Paul Nasca[0], which midigates these artifact by (1)carefully choosing the size and placement of grains and (2)randomly changing the phase of each grain before recombining. You can see the algorithm here[1]. The results are absolutely incredible. You can end up slowing a sample down by 800% or more with no artifacts. For example, here[2] is the Windows 95 startup sound extended to be a little over 6 minutes long. The reverb you hear isn't added, that's just what is sounds like. Also, if you didn't notice from the page, it's one of the default plug-ins in Audacity.
