Removal Plugin Free [2021] — Noise

Trained on thousands of voice and noise samples. Uses deep learning to isolate speech even under heavy background (e.g., traffic, café noise).

No free plugin matches iZotope RX’s machine learning or spectral repair, but for removing hiss, hum, and ambient noise, the above four plugins are professional-grade and cost nothing. noise removal plugin free

No “musical noise” artifacts. Great for cleaning high-frequency hiss (tape, converters) without damaging transients. Requires careful band setup. Trained on thousands of voice and noise samples

Instead of broadband subtraction, it compresses/expands specific frequency ranges when they fall below a threshold. Effectively ducks hiss in silent passages. No “musical noise” artifacts

Extremely effective for steady-state noise (air conditioners, preamp hiss). Can cause “underwater” artifacts if reduction set too high (>30 dB).

No learn function; you must manually set threshold. GUI is basic but functional. 3.2 ReaFIR (Cockos) – Most Powerful | Aspect | Details | |--------|---------| | Developer | Cockos (part of REAPER) | | Type | FFT-based subtractive / dynamic EQ | | Formats | VST, AU (free standalone) | | OS | Windows, macOS, Linux | | Key feature | “Subtract” mode with noise profile capture |

Uses an adaptive noise floor estimation with adjustable thresholds. Unlike simple gates, it reduces noise across all frequencies proportionally.
