What is Background Noise Remover?
Background Noise Remover cleans up steady background noise such as laptop fans, air conditioners, microphone hiss, room rumble, and 50Hz/60Hz electrical power hum from voice recordings and podcasts. Using client-side digital signal processing — including a sub-bass rumble high-pass filter, multi-harmonic AC hum notch filter, adaptive downward expander noise gate, and vocal presence enhancer — it makes speech clearer in seconds.

Tips & Best Practices
- 1
In Nepal and most of Asia/Europe, electrical mains hum runs at 50 Hz — select the 50 Hz Hum Filter to remove buzz from ungrounded microphones.
- 2
Avoid setting Noise Reduction Strength to 100% on very quiet voices; 55%–75% gives the most natural speech decay.
