What it removes
Room tone and hiss
Broadband background noise from cheap mics, laptop fans, and tape.
Electrical hum
The steady 50/60 Hz buzz picked up from mains power and bad cables.
Street and field noise
Traffic, wind, and air conditioning behind an interview or voice memo.
Uneven loudness
Optional −16 LUFS normalisation so the result sits at broadcast level.
Questions
Will it distort the voice?
The cleaner is tuned to preserve speech clarity; extreme noise reduction on very low-quality audio can introduce mild artefacts.
Does it work on music?
It's optimised for voice. For separating vocals from instrumentals, use the Vocal Separator.
