# Prism Spectrum — DAW plugin POC

# Prism — DAW plugins
|

|

A proof-of-concept JUCE 8 plugin (VST3 / AU / Standalone, macOS) that renders Prism's
|
||||
Spectrum scope inside a DAW. It **reuses Prism's existing C++ DSP** (`native/src/spectrum.cpp`,
|
||||
`dsp_utils.cpp`) and the **existing React canvas UI** (`src/plugin-ui`, which imports
|
||||
`src/renderer/visualizers/SpectrumAnalyzer.ts`).

JUCE 8 plugins (VST3 / AU / Standalone) that render Prism's scopes inside a DAW —
|
||||
one plugin per scope: **spectrum, oscilloscope, vectorscope, spectrogram, VU meter,

loudness meter, waveform**. They **reuse Prism's existing C++ DSP** (`native/src/*.cpp`)
|
||||
and the **existing React canvas UI** (`src/plugin-ui`, importing the unchanged
|
||||
visualizers from `src/renderer/visualizers/`). Built for macOS and Windows; Linux
|
||||
untested but should follow the same recipe.

## Build & run (Windows)
|

|

Prereqs: Visual Studio 2022 with the "Desktop development with C++" workload,
|
||||
CMake ≥ 3.22, Node.js. Modern Win10 / Win11 ships with the Microsoft Edge WebView2
|
||||
Runtime preinstalled; if it's missing, install the "Evergreen Standalone Installer"
|
||||
from Microsoft.
|
||||
|
||||
```sh
|
||||
npm install
|
||||
npm run plugin-ui:build
|
||||
cmake -B plugin\build -S plugin -G "Visual Studio 17 2022" -A x64
|
||||
cmake --build plugin\build --config Release
|
||||
```
|
||||
|
||||
`COPY_PLUGIN_AFTER_BUILD` targets the system VST3 folder
|
||||
(`C:\Program Files\Common Files\VST3\Prism *.vst3`), which **needs admin
|
||||
privileges**. Either run the `cmake --build` step from an elevated shell, or copy
|
||||
the built bundles from `plugin\build\Prism*_artefacts\Release\VST3\` into your
|
||||
user-local VST3 folder (`%LOCALAPPDATA%\Programs\Common\VST3\`) by hand — most
|
||||
DAWs scan both.
|
||||
|
||||
Dev-server mode works the same as macOS: `-DPRISM_DEV_SERVER=ON` + `npm run plugin-ui:dev`.
