In this repository you can find all of my VST3 plugins written in Rust using the nih-plug framework and the Vizia UI library.

Additional Credits

Most plugins (all in the future) are using modified KnobParam implementations from this repository by Daniel Fernandes

Building

After installing Rust, you can compile the plugins as follows:

cd [plugin-directory-name]
cargo xtask bundle [plugin-name] --release

Current plugin names are as follows:

• biquad_filter
• chorus
• flanger
• disperser
• mslr
• phaser

If i forget to update this file, the plugin name can be found in the bundler.toml file in each of the folders.

Build files will be in the target/bundled/[plugin-name.vst3] folder. You can then find the proper version of .vst3 file there and copy it to your VST3 plugin folder.

On Windows the vst3 plugin folder is usually C:\Program Files\Common Files\VST3 or C:\Program Files (x86)\Common Files\VST3.

Descriptions

Chorus

Simple chorus plugin that adds 3 voices (technically 6, because it's stereo) to the input signal using interpolated delay lines.

Flanger

Flanger/Vibrato plugin using interpolated delay lines. To achieve vibrato effect set the feedback to 0%, wet to 100% and dry to 0%.

Phaser

3-stage stereo phaser plugin using first order allpass filters.

Phase Disperser

Multiple Allpass filters in series create a phase dispersion effect. A very simplified description is that through phase shifting it delays lower frequencies creating the unique liquid-ish sounding effect.

MSLR (Mid Side Left Right)

This effect has two functions:

• adjusting volume of mid and side channels of a signal
• simple panning of a signal

Mid/side encoding is done using the following formulas:

mid = (left + right) * 0.5;
l_side = (left - right) * 0.5;
r_side = (right - left) * 0.5;

Biquad Filter

A simple biquad filter with a first and second order lowpass, highpass and allpass, and bandpass, notch, low/high shelf and a peak options.

Note

These plugins are not production-ready. They are written as a side-project to learn how DSP effects work. I test my plugins myself and there is always a chance that with certain parameter combinations the plugin will start outputting constant DC signal or very loud signal, because of an infinite feedback loop or simply a mistake in the code. If such a thing happens, open an issue and describe the problem and parameter values that cause problems.
