Paul's Extreme Sound Stretch - Paulstretch for short - isn't your average time-stretching application.
Capable of stretching audio files to 10,000 times their original size, it can make a piece of music that lasts a few minutes go on for several days! Even more incredibly, the results sound amazing - so good, in fact, that a stretched version of a track by no, er, less than Justin Bieber made with it went viral. It's quite a thing to behold the original version's pop hooks turn into wave after wave of glacial shoegaze bliss. Paulstretch is more than just a novelty, though, with its ability to stretch pretty much any sample into a weird and wonderful soundscape.

Step2: To load music into Paulstretch, select File>Open Audio File from the menu. Navigate to the file you want to load, then double-click it to open it. Take the Stretch time down to about 4x by dragging the bar near the top of the interface.
Step 3: Press the Play button (bottom left-hand corner) to hear how the audio sounds. To hear the original version, right-click Play. Quite a difference! Try different Stretch and Window Size parameter combinations. Export sounds with File>Render and Save Audio File.
