Free App Lets You Stretch Justin Bieber 800%!

Free Music Software: Remember yesterday’s post about turning Justin Bieber’s U Smile into ambient music by slowing it down 800%?

The secret is a free app for Windows & PC, Paul’s Extreme Sound Stretch.

It is designed specifically for extreme sound stretching of the audio (like 50x) and for applying special effects by “spectral smoothing” the sounds. It can transform any sound/music to a texture. The program is Open-Source and it’s released under the version 2 of the General Public License.


  • It produces high quality extreme sound stretching. While most sound stretching software sounds bad when trying to stretch the sounds a lot, this one is optimized for extreme sound stretching. So, the stretch amount is unlimited.
  • You can play the stretched sound in real-time (including the possibility to “freeze” the sound) or you can render the whole sound or a part of it to audio files
  • It has many post-processing effects, like: filters, pitch/frequency shifters
  • Support for WAV, OGG VORBIS files and MP3 files
  • It is Free Software

I’ve embedded several more examples below, which feature science fiction themes with extreme audio stretching.

Try it out and let me know what you think!

And if you come up with something cool, post it on the Web and add a link to it below!

  1. the bieber thing sounds amazing but lets keep in perspective that the only reason it became so popular is because no one expected a justin bieber song could sound like this. i think i made a better one than this but no ones going to care because im not a pop tart like bieber boy ;-(
