## Description

PaulXStretch is a free app and AUv3 plugin implementing the PaulStretch algorithm (Paul's Extreme Time Stretch). Its updated UI is optimized for different platforms and screen sizes, and it excels at radical sound transformation—ideal for ambient sound design. It can turn any short audio into hours-long soundscapes, with input through Capture or by loading files. After tweaking parameters, choose a slice to process and loop, press play to hear the effect, and render offline or record live to capture the result. Saved audio can be accessed or shared from the Files app.

The AUv3 version offers the same capabilities with live input, enabling internal capture for stretching. This software is free to use; the UI has been adapted across platforms. Note: it's designed for dramatic transformations rather than subtle corrections, making it perfect for ambient textures and experimental sound design.
