Version: v1.0.1
A real-time noise reduction plugin using spectral subtraction. Designed for cleaning up dialogue, vocals, and instrument recordings with minimal artifacts and low latency.
- ✅ Spectral subtraction algorithm — Effective broadband noise reduction
- ✅ Real-time noise profile learning — Click "Learn Noise" to capture the noise floor
- ✅ Adjustable reduction amount — Control the strength of the noise reduction
- ✅ Difference Mode — Audition only the removed noise for fine-tuning
- ✅ Built-in spectrum analyzer — Visual feedback of the frequency response
- ✅ Low latency — ~46ms at 44.1kHz
- ✅ Preset saving and loading — Save and recall your favorite settings
- ✅ Code-signed with SSL.com certificate — Trusted and verified
- ✅ Hard clipper at output — Prevents clipping from overlap-add artifacts
- ✅ Output gain in decibels — Display shows dB (0.0 dB at unity gain)
- ✅ Noise profile persists across bypass — Profile stays intact when bypassing and re-enabling the plugin
- Windows 10 or 11 (64-bit)
- VST3-compatible DAW (FL Studio, Reaper, Ableton, Cubase, etc.)

| Issue | Solution |
|---|---|
| Plugin not showing up | Restart your DAW and rescan plugins |
| Audio dropouts | Increase your DAW's buffer size |
| Noise profile lost on bypass | Fixed in v1.0.1 — profile now persists |
| Clipping at output | Reduced in v1.0.1 — hard clipper added |
- Output Clipping Fix: Added a hard clipper at the output stage to prevent peaks above 0 dBFS caused by overlap-add artifacts.
- Output Gain Display: Now shows values in decibels (
0.0 dBat unity gain) for better usability. - Noise Profile Persistence: The noise profile now persists across bypass/re-enable — no need to re-learn after bypassing.
