How to clean up audio
- 1

- 2

- 3
Listen, then download the clean file.
Four things that go wrong
Background noise, such as hiss, hum, traffic, or chatter. Echo, when the room rings after each word. A muffled or thin voice, from a cheap mic, a phone line, or a laptop far away. And distortion: crackle or harsh breakup from recording too loud. The cleaner fixes all four at once, so you don't need to work out which one you have.
For your next recording, get closer to the mic, record in a room with soft furnishings, and keep the level out of the red.
Questions
Which recordings is it for?
Speech: interviews, podcasts, video voiceovers, voice notes, and lectures. It's an AI audio cleaner made for voices, so music and other sounds are removed.
Is it free?
Yes, for the first minute of each file, 3 times a day, with no sign-up. For longer files, see pricing.
How is it different from Remove noise?
The audio cleaner rebuilds the voice, so it fixes echo and muffled sound too. Remove noise only filters out the noise, keeping the voice exactly as recorded. If the voice already sounds fine, that's the better pick.
Why is my quiet recording louder now?
After cleaning, the voice is set to a standard volume, so a recording that was too quiet comes back at a normal level.
Can I make it less strong?
Yes. Strength goes from Full to Subtle. Closer to Subtle, more of the original recording is mixed back in.
Does it work on video?
Yes. Add a video and you get the same video back, cleaned.
Which files work?
Audio as WAV, MP3, M4A, AAC, FLAC, OGG, Opus, WebM, AIFF, and video as MP4, MOV, MKV, WebM, AVI. You get the same kind of file back.
