A Rust implementation of the Freeverb algorithm.
Freeverb was originally written in C++ by "Jezar at Dreampoint", and was released into the public domain in June 2000. It is now widely used in various incarnations in multiple software packages.
This implementation of Freeverb in Rust is an almost direct conversion of the original source, created as a demonstration project for a talk I gave about Rust at the Audio Developer Conference 2018. The code has been updated since then, so if you want to follow along with the talk then take a look at the adc-2018 branch.
A difference from the original implementation is that delay line buffers are dynamically allocated so that lengths can be adjusted for sample rates other than 44.1kHz.
This contains the core implementation of Freeverb, with a simple interface.
A static library that provides C bindings to the Freeverb processor, used by app_juce.
This contains a very minimal generic module+parameter library
The freeverb processor wrapped up as an AudioModule, currently only used by app_gtk.
A very basic audio+GUI application that runs the Freeverb processor.
You will need gtk4 installed on your system for this to work.
A very basic JUCE application that runs the Freeverb processor via a statically linked library.
A library that provides a Wasm interface to the Freeverb processor.
Also in the folder is a small web application that runs the Wasm processor.
