System-level microphone gain and high-quality audio processing for Windows. Captures microphone input via NAudio (WASAPI), applies a DSP chain — Noise Gate, Equalizer, Limiter — and routes the result to a virtual audio device such as VB-CABLE.
| Module | Description |
|---|---|
| Software Amplifier | Boosts microphone level beyond the OS gain limit |
| AI Noise Suppression | RNNoise-based removal of fans, keystrokes, and other background noise even while you speak (optional, requires rnnoise.dll — see native/runtimes/README.md) |
| Noise Gate | Suppresses ambient noise, keyboard sounds, and breath |
| Equalizer | Multi-band EQ for tailoring vocal tone |
| Limiter | Prevents clipping at high gain settings |
| Virtual device routing | Sends processed audio to VB-CABLE or any virtual input |
- Windows 10/11 (x64 or x86)
- VB-CABLE (https://vb-audio.com/Cable/) or another virtual audio device
- Install VB-CABLE.
- Download the latest release and extract the zip.
