Question 1

How do I remove background noise from a recording?

Accepted Answer

Upload your audio file (WAV, MP3, FLAC, M4A, OGG, or AIFF) to the Noise Reducer. The AI analyzes the noise floor automatically and removes hiss, hum, traffic, HVAC, and similar background noise. Adjust the strength slider (0–100%) to control how aggressive the reduction is.

Question 2

Will noise reduction make my voice sound robotic or underwater?

Accepted Answer

No — the AI-based approach is designed specifically to avoid the artefacts of older spectral subtraction. Vocals and music retain their natural timbre even at higher reduction strengths. If you push the strength to 100% on a very noisy source, you may hear mild softening — back off to 60–80% for transparent results.

Question 3

How is AI noise reduction different from a noise gate?

Accepted Answer

A noise gate cuts everything below a threshold — useful for silence but it leaves noise during the actual signal. AI noise reduction analyzes the audio continuously and subtracts noise even while the signal is playing, so background hum disappears beneath the voice instead of only between sentences.

Question 4

Can it remove electrical hum (50 Hz or 60 Hz)?

Accepted Answer

Yes — the de-hum module specifically targets mains hum and its harmonics. Choose 50 Hz for Europe, Asia, and most of the world; 60 Hz for the Americas. The filter removes the fundamental plus 100/120/200/240 Hz harmonics without affecting nearby musical content.

Question 5

Is the noise reducer free?

Accepted Answer

Yes. The Noise Reducer is part of the Audio Restoration suite, free with a Mixing & Mastering AI account. Free accounts include monthly processing minutes; paid plans process unlimited audio and unlock advanced parameters for difficult sources.

Question 6

What if my recording has hum, hiss, AND clicks?

Accepted Answer

Use them all together — the Restoration pipeline lets you chain de-hum, de-noise (broadband hiss), de-click, and de-crackle in one pass. Each has its own strength slider, so you can dial in exactly what your recording needs without over-processing.
