Paulstretch is an innovative (and free) little program that allows users to slow down audio up to hundreds of times without suffering any changes in pitch. The program does this by sectioning off portions of the audio as it stretches it out, rather than simply spreading the audio as one big chunk. It gained a bit of internet notoriety a while back when somebody discovered that by slowing down a Justin Bieber song 800%, one can transform utter garbage into angelic Sigur Ros-ian introspection. Of course, in this “stretching” process you also turn a four-minute song into a 30+ minute one, but improvement is improvement, I suppose.
To demonstrate, I took a little four-minute demo I made on GarageBand and put it into Paulstretch. The result is a half hour of great writing/sleeping/dying(?) music. I don’t expect that you’ll listen to the whole thing, and you can get a pretty clear idea of what the program can do with a quick comparison of the above audio with the original here.
[Oh, and the “Album Art” I used is a picture from Circa 1983, the photo roll of one of the best photographers on the internet. Seriously. Check him out.]
