Free App, PaulXStretch, Lets You Do Extreme Time-Stretching Of Audio

Sonosaurus, creator of the iOS app ThumbJam, has released an updated version of PaulXStretch, a free multi-platform application designed for the extreme time-stretching of audio.

PaulXStretch is designed for radical transformation of sounds. It is not designed for subtle time or pitch correction. It can turn any audio into hours or days of audio, so ambient music and sound design are common uses.

PaulXStretch is based on the PaulStretch algorithm (Paul’s Extreme Time Stretch, originally developed by Nasca Octavian Paul), and specifically the PaulXStretch version from Xenakios. The UI has been updated, adapted for various screen sizes, and built for the latest platforms.

Pricing and Availability

PaulXStretch is available now for iOS, Linux, Mac & Windows, and the source code is available via Github.

  1. Probably. The first time I heard Paul’s Stretch was a stretched Justin Beiber song that was so hauntingly beautiful. Probably makes any pop song hauntingly beautiful.

    I agree it is nice to see this process continue to be available in updated form. Lots of platforms available, too.

  2. For many, PaulXStretch is an ambient electronic composer’s old friend. Feels right that this still receives updates.

  3. Another developer was able to get all the original folks involved with original PS to let him take over keeping it current. He even ported it over to IOS. That’s where this iteration started from as folks on the audiobus forum asked if someone could make an AUv3 and all this happened.

  4. I can’t believe I only recently started using the standalone version(much more complete). I’ve been using it in Audacity for drones forever…

  5. I love to see such wonderful stewardship of these classic (and ancient!) bits of open-source software. Gives me hope that somethings may actually endure on the internet.
