PaulXStretch is a free application and AUv3 plugin developed by Sonosaurus LLC. It is based on the PaulStretch algorithm, specifically the PaulXStretch version from Xenakios. The user interface has been updated and adapted for various platforms and screen sizes.

This software is most suitable for radical transformation of sounds and is not designed for subtle time or pitch corrections. It is ideal for creating ambient music and sound design. With PaulXStretch, you can turn any short audio into an hours-long ambient soundscape effortlessly.

Getting audio into the application is easy, either by using the "Capture" feature or by loading an existing audio file. Once you have audio in the application, you can start tweaking all the parameters, choose the portion of the audio to use and loop over, and more. Remember to press the play button to enable the processing. You can then export the processed audio either as an offline render to a file or as a live recording of your session. The saved audio can be accessed and shared through the Files app or by sharing it directly.

The AUv3 plugin version of PaulXStretch offers the same capabilities as the standalone application, but with the added ability to feed it live input for stretching.

PaulXStretch is a powerful tool for sound manipulation and experimentation, and it is available for free. Enjoy exploring its possibilities!
