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.
- Analysis of the Freeverb algorithm
- Original freeverb source is available in the
freeverbsource.zipfile in this repo.
This implementation of Freeverb in Rust is an almost direct conversion of the original source, created as a demonstration project for a talk Ian Hobson gave about Rust at the Audio Developer Conference 2018.
There are a couple of (intentional) differences to the original implementation:
- Delay line buffers are dynamically allocated for simplicity. This may have a performance impact; making the buffer static with generic constants is an alternative.
- 64 bit processing is used internally whereas the original is 32 bit. Making the sample type configurable is an option.
