# Saftpumpe
|
||
|
||
A VCA-style bus compressor plugin for macOS (arm64). Built with JUCE.
|
||
|
||
Saftpumpe delivers the analog punch of classic rack-mounted bus compressors — soft-knee compression, program-dependent auto-release, and subtle tanh saturation for warmth. The skeuomorphic UI features silver metal faders on a brushed aluminum faceplate.

## Obligatory AI slop disclaimer
|
||
|
||
Yes, this software was built with the help of AI. If that is an issue for you, please use a different plugin. Thank you for your understanding.
|
||
|
||
## Compatibility
|
||
|
||
I have tested this on macOS (M2 Pro Mac Mini) with FLstudio. That's it. If it breaks on your setup, well, that's bad, I probably can't do much about it.
|
||
|
||
## Features
|
||
|
||
- **Analog-modeled VCA compression** with soft-knee transition
|
||
- **Program-dependent auto-release** — faster for transients, slower for sustained material
|
||
- **Tanh saturation** for musical harmonic coloring
|
||
- **7 parameters:** Threshold, Ratio, Attack, Release, Knee, Makeup Gain, Dry/Wet Mix
|
||
- **Auto Release** toggle switch
|
||
- **Real-time waveform scope** (input + compressed output overlay)
|
||
- **LED-style meters:** Gain Reduction, Input, Output
|
||
- **HiDPI scaling** (0.75x – 2.0x)
|
||
|
||
## Formats
|
||
|
||
- VST3
|
||
- Audio Unit (AU)
|
||
- Standalone application
|
||
|
||
## Build
|
||
|
||
Requires CMake and JUCE (cloned into the project directory).
|
||
|
||
```bash
|
||
# First time only — clone JUCE
|
||
git clone --depth 1 https://github.com/juce-framework/JUCE.git
|
||
|
||
# Build
|
||
make
|
||
|
||
# Or manually
|
||
mkdir build && cd build
|
||
cmake .. -DCMAKE_BUILD_TYPE=Release
|
||
cmake --build . -j$(sysctl -n hw.ncpu)
|
||
```
|
||
|
||
The build automatically installs VST3 and AU to:
|
||
- `~/Library/Audio/Plug-Ins/VST3/Saftpumpe.vst3`
|
||
- `~/Library/Audio/Plug-Ins/Components/Saftpumpe.component`
|
||
|
