# NIH-plug [](https://github.com/robbert-vdh/nih-plugs/actions/workflows/test.yml) This is a work in progress JUCE-lite-lite written in Rust to do some experiments with, as well as a small collection of plugins. The idea is to have a statefull but simple plugin API that gets rid of as much unnecessary ceremony wherever possible, while also keeping the amount of magic to minimum. Since this is not quite meant for general use just yet, the plugin API is limited to the functionality I needed and I'll expose more functionality as I need it. See the documentation comment in the `Plugin` trait for an incomplete list of missing functionality. ### Table of contents - [Plugins](#plugins) - [Framework](#framework) - [Current status](#current-status) - [Building](#building) - [Plugin formats](#plugin-formats) - [Example plugins](#example-plugins) - [Licensing](#licensing) ## Plugins Check each plugin's readme for more details on what the plugin actually does and for download links. - [**Diopser**](plugins/diopser) is a totally original phase rotation plugin. Useful for oomphing up kickdrums and basses, transforming synths into their evil phase-y cousin, and making everything sound like a cheap Sci-Fi laser beam. ## Framework ### Current status It actually works! There's still lots of small things to implement, but the core functionality and including basic GUI support are there. Currently the Windows version has only been tested under Wine with [yabridge](https://github.com/robbert-vdh/yabridge), and the macOS version hasn't been tested at all. Feel free to be the first one! ### Building NIH-plug works with the latest stable Rust compiler. After installing [Rust](https://rustup.rs/), you can compile any of the plugins in the `plugins` directory in the following way, replacing `gain` with the name of the plugin: ```shell cargo xtask bundle gain --release ``` ### Plugin formats NIH-plug can currently export VST3 plugins, with CLAP support being worked on right now. Exporting a specific plugin format for a plugin is as simple as calling the `nih_export_<format>!(Foo);` macro. The `cargo xtask bundle` commane will detect which plugin formats your plugin supports and create the appropriate bundles accordingly, even when cross compiling. ### Example plugins The best way to get an idea for what the API looks like is to look at the examples. - [**gain**](plugins/examples/gain) is a simple smoothed gain plugin that shows off a couple other parts of the API, like support for storing arbitrary serializable state. - [**gain-gui**](plugins/examples/gain-gui) is the same plugin as gain, but with a GUI to control the parameter and a digital peak meter. - [**sine**](plugins/examples/sine) is a simple test tone generator plugin with frequency smoothing that can also make use of MIDI input instead of generating a static signal based on the plugin's parameters. ## Licensing The framework, its libraries, and the example plugins in `plugins/examples/` are all licensed under the [ISC license](https://www.isc.org/licenses/). However, the [VST3 bindings](https://github.com/RustAudio/vst3-sys) used by `nih_export_vst3!()` are licensed under the GPLv3 license. This means that unless you replace these bindings with your own bindings made from scratch, any VST3 plugins built with NIH-plug need to be able to comply with the terms of the GPLv3 license. The other plugins in the `plugins/` directory may be licensed under the GPLv3 license. Check the plugin's `Cargo.toml` file for more information.
