Four recording problems fixed in one pass

When one recording has noise, echo, and a poor microphone at once, one run fixes them together and sets the volume.

  • Background noise & hum

    Audio cleanup for hiss, fan noise, and street noise

    There are no settings to work out. Audo's audio cleaner takes out air conditioning, traffic, and hiss, and makes the speech clearer.

  • Room echo & reflections

    Room echo, along with the noise

    Empty offices, kitchens, and meeting rooms with glass walls add echo on top of the noise. Both go in the same run. If echo is the only problem, use Remove echo.

  • Muffled & distant mics

    Recordings from laptops, headsets, and phones

    A laptop's built-in mic, wireless earbuds, and phones often sound muffled or far away. The cleaner makes the voice sound fuller and closer. For voice memos and calls, use Voice cleaner.

  • Videos & full episodes

    Clean the sound of MP4 and MOV videos

    Add MP4, MOV, MKV, WebM, AVI videos up to 10 GB, and the picture is copied as it is. Signed in, files can be up to 10 hours long. To compare tools, see best AI noise removal tools.

Four things that go wrong

Audo's AI audio cleaner — powered by Audio enhancer — 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 comes back in about 8 seconds, a 20-minute recording takes about 38 seconds, and a full 1-hour file finishes in under 2 minutes (about 1 minute 42 seconds for audio). It rebuilds the voice, then sets the whole file to podcast loudness (−16 LUFS).

Most rough recordings suffer from more than one flaw at once: steady hiss or traffic in the background, bare-wall room echo after each word, thin or muffled tone from a distant mic, and harsh clipping on loud laughs. The board meeting in the player above had the first three.

For your next recording, sit closer to the microphone, 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 and video online?

Add the file to Audo's AI audio cleaner, choose a strength, and download the cleaned version. Noise, echo, muffled sound, and distortion are fixed together in one pass, and loudness is leveled automatically.

How do I clean up the audio in a video?

Upload the MP4, MOV, or WebM video straight to Audo's audio cleaner rather than extracting the audio first. Audo puts the cleaned speech back into the same video with the picture untouched.

Is there an app to clean up audio on iPhone?

You don't need to install one. Audo works directly in Safari or Chrome on iPhone and Android: add the recording or video, then download the clean version.

Can I clean up podcast WAV or MP3 files longer than 30 minutes?

Yes. Signed in, Audo cleans audio and video files up to 10 hours and 10 GB in one pass, with no subscription. To compare limits, see Adobe Podcast Enhance: limits and alternatives.

Can ChatGPT or Claude clean up audio?

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

Which recordings is it built for?

Spoken audio and video: interviews, podcasts, YouTube voiceovers, lectures, and meetings. Because Audo's audio cleaner is built for voices, singing and instruments are removed; for songs, use Vocal remover.

How is it different from Remove noise?

Audo's Audio cleaner rebuilds the voice so it fixes room echo, muffled mics, and harsh breakup alongside noise. Audo's Remove noise only filters out background noise and keeps the voice exactly as recorded — pick Remove noise when your mic and room already sound good.

Can I make the effect less strong?

Yes. On Audo's audio cleaner, slide Strength (10–100%) from Full toward Subtle to blend more of your original recording back in.
