Background

Spice FX shipped commercially before being open-sourced; it's the only audio plugin in the lineup and the bridge between the embedded/audio world and the VST plugin world. It runs across Windows, macOS and Linux as VST3, AU and LV2, with a multi-stage processing chain, up to 4× oversampling and an analog-modeled UI.
