Developer builds six open-source VST3 audio plugins using JUCE 8 framework

A developer has released a suite of six audio plugins — including a compressor, limiter, distortion unit, spectrum analyser, and wavetable synthesiser — all built with JUCE 8 in C++ and published under the GPL v3 licence. The plugins are available as VST3 and standalone formats through a self-built store at esp-plugin-store.vercel.app. Each plugin was developed sequentially, with each one extending the technical challenges left unresolved by the previous build. The project highlights both the strengths of the JUCE framework, such as its DSP modules and parameter automation system, and its limits, particularly around audio visualisation, which required significant custom coding. A key design principle throughout was keeping the audio thread free of blocking operations, with all visualisation work offloaded to the UI thread via lock-free FIFOs.
