What Noise Does It Remove?
- Fan and air conditioning hum — constant background drone from HVAC, fans, heaters
- Street and traffic noise — cars, sirens, construction outside the window
- Keyboard and mouse clicks — typing sounds during calls and recordings
- Electrical hum and buzz — 50/60 Hz hum, ground loop noise, cable interference
- Wind noise — outdoor recordings with microphone wind buffeting
- Room echo and reverb — partial reduction of room reflections
Strength Levels
- Light (6 dB) — Gentle cleanup that preserves natural room ambiance. Best for recordings in quiet environments with minor noise.
- Moderate (12 dB) — Balanced noise removal suitable for most recordings. Removes noticeable background noise while keeping voice natural.
- Aggressive (20 dB) — Maximum noise suppression for very noisy recordings. May slightly affect voice quality in exchange for cleaner audio.
Best Results Tips
- Speech recordings work best — DeepFilterNet3 is optimized for speech enhancement. It works on music too but is designed for voice.
- Start with Moderate — try moderate first, then switch to aggressive if noise persists, or light if the result sounds too processed.
- Source quality matters — heavily distorted or clipped audio cannot be fully restored. The AI can remove noise but cannot fix damaged recordings.
