+During December 2023 we are sunsetting, archiving and deprecating this repository and version of the p5.sound project, while we prepare the release of the new version of the library, currently being built at [https://github.com/processing/p5.sound.js](https://github.com/processing/p5.sound.js).
+
 p5.sound brings the [Processing](http://processing.org) approach to [Web Audio](http://w3.org/TR/webaudio/) as an addon for [p5.js](http://github.com/processing/p5.js). Functionality includes audio input, playback, manipulation, effects, recording, sequencing, analysis and synthesis. The library is designed to be used in tandem with [p5.js](http://p5js.org).
