# BEAMGRID
|
||
|
||
A JUCE-based VST3 / AU spectrum analyzer with a fully black UI, teal accents,
|
||
and a configurable display.
|
||
|
||
## Features
|
||
|
||
- **Three display modes** (`MODE` knob):
|
||
- **BARS** — classic log-spaced spectrum bars with peak-hold caps.
|
||
- **SPECTRUM** — a smooth (quadratic-spline) waveform trace of the spectrum,
|
||
with a matching smooth peak-hold wave. Use the `SMOOTH` knob to go from
|
||
raw/edgy to heavily smoothed.
|
||
- **LED** — an LED-meter style view (`LEDS` knob sets LEDs per bar).
|
||
- **Frequency range** fixed to **20 Hz – 20 kHz**.
|
||
- **HUE** knob rotates the hue of every UI accent (knob arcs, peaks, title)
|
||
without altering the underlying data.
|
||
- **UI scaling** dropdown (75% – 300%) in the top-right.
|
||
- Per-project **size & scale persistence** (stored in the plugin state).
|
||
|
||
## Parameters
|
||
|
||
| Knob | Range | Description |
|
||
|-------------|------------------|-----------------------------------------------|
|
||
| PEAK GRACE | 0 – 2000 ms | Grace period before a peak-hold marker decays |
|
||
| PEAK FALLOFF| 0 – 1 | Peak-hold decay rate |
|
||
| BAR FALLOFF| 0 – 1 | Spectrum bar release speed |
|
||
| BARS | 8 / 16 / 32 / 64 / 128 | Number of spectrum bands (snaps) |
|
||
| HUE | 0 – 1 | Rotates the UI accent hue (0.5 = no change) |
|
||
| MODE | 1 / 2 / 3 | BARS / SPECTRUM / LED |
|
||
| LEDS | 4 – 48 | LEDs per bar in LED mode |
|
||
| SMOOTH | 0 – 1 | Waveform smoothing amount in SPECTRUM mode |
|
||
| GRID | 0 – 1 | Grid (frequency/level) visibility / brightness|
|
||
| ZOOM | 98.0% – 102.0% | Grid zoom about the plot centre |
|
||
| GRID FADE | 0 – 1 | Fades inner grid lines; outer border stays |
|
||
| CURVING | 0 – 1 | LED corner radius (0 = square, 1 = rounded) |
|
||
| TILT | -1 – 1 | Spectral tilt: + boosts highs / cuts lows, - does the reverse (0 = flat) |
|
||
|
||
## Building
|
||
|
||
Requires [CMake](https://cmake.org/) (>= 3.22) and a JUCE-supported
|
||
toolchain (Xcode / clang on macOS, MSVC / GCC on Windows, etc.). JUCE is
|
||
fetched automatically by CMake.
|
||
|
||
```sh
|
||
cmake -B build -G Ninja
|
||
cmake --build build --config Release
|
||
```
|
||
|
||
The built plugins are installed to your system plugin folders:
|
||
|
||
- `build/BEAMGRID_artefacts/Release/VST3/BEAMGRID.vst3`
|
||
- `build/BEAMGRID_artefacts/Release/AU/BEAMGRID.component`
|
||
|
||
Then rescan in your DAW (FL Studio, REAPER, Logic, etc.).
|
||
|
||
