I will build your custom vst3 and au audio plugin in juce
About this Gig
I build audio plugins in C++ with JUCE: effects, synths, samplers and drum machines, shipped as VST3 and AU for macOS (Apple Silicon and Intel) and VST3 for Windows.
This year I designed and released a full line of my own plugins: a microtonal synth with a patch bay, sequencer and drum machine; a BBD delay; an algorithmic reverb; a cassette tape effect; a measured mastering processor; a drum machine. The panels in the gallery are real, from shipped products.
WHAT YOU GET
- DSP written for your sound, tested by ear and measured (level, latency, CPU)
- A custom-drawn, resizable interface, or your designer's files built pixel-true
- Builds validated with pluginval and auval, tested in a DAW
- Full source code, no GPL, yours to own
- Optional: signed and notarised installers with your certificates

FAQ
Do I get the source code?
Yes. Every package includes the full JUCE project, with no GPL code, so you own it.
Can you build the design my designer made?
Yes. Send the Figma or PNG files and I build them pixel-true and resizable. No designer? Standard and Premium include a custom-drawn interface.
Do you build for Windows and Pro Tools?
Basic is macOS (VST3 and AU). Standard and Premium add a Windows VST3 build. AAX for Pro Tools is not offered yet.
Can we talk on a call?
I work in writing through Fiverr messages. You get a written plan before you order and a written report with every delivery, with the measured numbers.
