# InstaShadow
|
|
|
|
Dual-stage mastering compressor plugin (VST3/AU/LV2) inspired by the Shadow Hills Mastering Compressor, built with JUCE.
|
|
|
|
## Features
|
|
|
|
- **Optical Compressor** — Port-Hamiltonian T4B opto-cell model with physically accurate two-stage release and CdS memory effect
|
|
- **Discrete VCA Compressor** — Feed-forward Class-A topology with 7 ratio settings (1.2:1 to Flood), 6 attack/release presets, and Dual release mode
|
|
- **Output Transformer** — 3 switchable transformer types (Nickel/Iron/Steel) with frequency-dependent saturation and 4x oversampling
|
|
- **Sidechain HPF** — Variable 20-500 Hz high-pass filter to prevent bass-induced pumping
|
|
- **Stereo Link** — Linked or dual-mono operation
|
|
- **Independent bypass** — Each section can be bypassed separately
|
|
- **GR Metering** — Dedicated optical and discrete gain reduction meters
|
|
- **State save/restore** — All parameters persist with DAW session
|
|
|
|
## Signal Flow
|
|
|
|
```
|
|
Input → SC HPF → Optical Comp (T4B) → VCA Comp → Transformer → Output
|
|
```
|
|
|
|
## Build
|
|
|
|
Requires [JUCE](https://github.com/juce-framework/JUCE) cloned at `../JUCE` relative to this project.
