What is background noise in audio?

Background noise includes hiss, hum, static, rumble and room noise that degrade recording quality.

What is 50Hz/60Hz hum?

AC power hum is electrical interference from power lines — 50 Hz in Europe/India, 60 Hz in the USA. A notch filter removes it precisely.

Can I remove wind noise?

Yes — use the "Low-frequency Rumble" preset which applies a high-pass filter at 80 Hz to eliminate wind and handling noise.

Will noise removal affect voice quality?

At moderate strength (3–6) the effect on voice is minimal. Higher strengths may soften some consonants.
