Erosion Delay is a Delay/Chorus audio effect created with C++/JUCE. It is available as a VST3 plugin or standalone program. It doesn’t reinvent the wheel or do anything particularly remarkable, but it is a fully featured, fully functioning audio plugin. It can be used as either chorus or delay effect and includes a preset system for saving and loading user presets.
