How to clean up audio

  1. 1

    Add the recording or video you want cleaned.

  2. 2

    Leave Strength at Full, or turn it toward Subtle.

  3. 3

    Compare it with the original, then download it.

Four things that go wrong

Audo's AI audio cleaner takes WAV, MP3, M4A, AAC, FLAC, OGG, Opus, WebM, AIFF recordings and MP4, MOV, MKV, WebM, AVI videos up to 10 GB without an account, and cleans the first minute of each for free, 3 times a day, with no sign-up. That first minute is usually back in about 11 seconds, and a 22-minute recording takes about 45 seconds. It rebuilds the voice, then sets the whole file to a standard volume, so a quiet recording comes back at a normal level.

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 meeting in the example above had the first three.

For your next recording, get closer to the mic, record in a room with soft furnishings, and keep the level out of the red. If you also want um, uh, and mouth sounds cut out after cleaning, compare the tools in Cleanvoice alternatives.

Questions

What is a free way to clean up audio?

Use Audo's audio cleaner: the first minute of each file is cleaned free, 3 times a day, with no sign-up. Cleaning a whole file is $0.05 a minute ($3.00 an hour), with no subscription (see pricing).

How do you clean up audio?

Add the file, choose a strength, and download the cleaned version. Noise, echo, muffled sound, and distortion are fixed together, so you don't need to work out which one you have.

How do I clean up the audio in a video?

Add the video itself, not just its sound. The cleaned speech goes back into the same video, and the picture isn't touched.

Is there an app to clean up audio on iPhone?

You don't need one. Audo works in your phone's browser, on iPhone or Android: add the recording, then download the clean version.

Can ChatGPT clean up audio?

Yes, once Audo is added to it. Attach the recording, ask ChatGPT to clean it up, and the cleaned file comes back from Audo. Claude can do it too. Add Audo to your assistant one time to use it in any chat.

Which recordings is it for?

Speech: interviews, podcasts, video voiceovers, voice notes, lectures, and meetings. It's an AI audio cleaner made for voices, so music and other sounds are removed.

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.

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.
