I work on audio plugins and I've created a few public utilities (C/C++/JS/Python) along the way which may interest you.

• 🔌 CPLUG - Thin C wrapper for VST3, AUv2, CLAP, and standalone builds with hot reloading.
• 📋 Awesome Audio Plugin Framework - List of small libraries for quickly bootstraping your own audio plugin templates (WIP)
• 🎨 nanovg_compat - Wraps my forks of the Metal and DirectX 11 ports of NanoVG. Contains a few extra utilities. Lazily named
• 🎨 juce_nanovg - Demonstration of 2 ways to use NanoVG within a JUCE app/plugin
• 🙏 xhl - My utils folder, all written as single header libraries. Inludes maths, debugging, GUI stuff, thread stuff, data structures
• 🎹 MiniMIDI - Connect to MIDI ports on Mac/Win. Serialize incoming data. Very low latency. Includes hot plugging
• 📈 fastmaths - Benchmarks of fast maths approximations. Also records margins of error across wide ranges. Contains most trigonometry & exponentials functions.
• 🔢 wavetable_algorithms - Standalone app using matplotlib (python) that displays time & frequency information of algorithmically generated wavetables. Outputs .wav & .flac files
• 🔢 EquoFO - Standalone app in python that takes equations and generates wavetables (wav/flac) & LFO presets for GHOST & Vital synthesisers
• 🔐 node-juce-unlocker - Nodejs package for unlocking JUCE apps. Based off of the JUCE Unlock your plugins tutorial, but uses JS instead of PHP
• 🧭 FigmaBoundsHeader - Figma plugin that exports coordinates of your layers / text / shapes to a C friendly .h file.
• 🧭 CSS2JUCE - (old) Same as above, except in C++ and the coordinates all use juce::Rectagle. Has nothing to do with CSS, sorry for awful naming. If you use JUCE, this is preferable to FigmaBoundsHeader, but worse in any other case.
