Musical software developer Sonosaurus has recently announced an update of their time-stretching software PaulStretch. The newest iteration of the app is called PaulXStretch.

The update includes many of the same features as the original with the addition of an updated user interface, adaptability to modern screen sizes, and functionality with the latest DAWs and operating systems.

As the name implies, PaulXStretch was designed to stretch audio, not just a little bit, but a lot!

The app takes small pieces of an audio clip and expands it to whatever duration you need.

Creator of PaulXStretch, Paul Nasca, was interviewed by NPR and explained how exactly the app works:

“The idea of it is pretty simple. I take a small chunk (usually around 100 milliseconds) of the audio file from the start position, and I smear it. First, I analyze a sound’s frequencies and then randomize a part of the sound’s characteristics and rebuild the chunk. I repeat the same process for another chunk of the audio file, and so on.”

Essentially, his algorithm allows users to generate hours, even days, of organic-sounding audio from even the smallest of audio clips.

The applications for this software are quite broad, and it has potential use for producers across many genres.

In particular, musicians in the ambient and meditative space could find excellent use of PaulXStretch. Users can quickly turn anything from a bell to a vocal chop into an organic pad.

The app’s interface is quite user-friendly, with numerous settings and effects to dial in your desired sound.

Once a clip is imported, there’s an option to stretch the sound and then modify it with pitch/frequency shift, along with a pair of low-pass and high-pass filters.

PaulXStretch allows you to layer in harmonics and determine the frequency spread. After a short amount of time, I was able to take a tiny audio sample and turn it into an epic, ambient pad!

Another benefit of the app is its IOS compatibility- perfect for mobile producers!

PaulXStretch is still in beta testing for IOS, though, so users looking to get this app will be required to install TestFlight and opt-in to be a beta tester!

To download the PaulXStretch plugin, follow the link to the website, select your operating system, and it will immediately start downloading!

PaulXStretch works in macOS X 10.10 and above and in Windows 7 and newer. It is available as a standalone application and AU, VST3, and AAX formats.
