What kinds of noise can it remove?
Steady background noise works best — fans, AC, computer hum, traffic, wind, keyboard and room hiss. Sudden loud noises and other people talking are harder to separate from the main voice.
Does it work for music?
It's trained for speech, so it may treat instruments as noise. Use it on voice recordings.
The voice sounds a little thin — what can I do?
Lower the strength to 60–80% to blend some of the original back in.
Can I clean the audio of a video?
Yes — drop in an MP4, MOV or WebM. The picture is copied as-is and the cleaned audio replaces the original.
Is my recording uploaded?
No. The noise suppressor runs on your device.
