AI Audio Enhancer for Free

An audio enhancer makes the voice in a recording or a video easier to hear. This AI audio enhancer lowers hiss, hum, fan, and room noise under speech, then lets you mix some original sound back in, raise the volume, and trim the ends. Upload MP3, WAV, M4A, MP4, or MOV, hear 30 seconds free, and download WAV audio or an MP4 with the picture unchanged.

What can an AI audio enhancer fix?

AI audio enhancement here means one thing: the voice gets clearer because the noise under it drops. An audio enhancer for speech does not master a song or turn the speaker into someone else.

Hiss under a quiet voice

A phone memo or an old tape has words buried in hiss. The audio enhancer lowers the hiss, and Volume lifts the voice.

Hum and fan noise on a call

A laptop fan or an electrical hum sits under every word. Enhance the audio and keep the take when the speaker still sounds like themselves.

Room tone in a classroom or hall

The lesson is there, but the room covers it. The voice rises above the room tone. Stop if consonants start to chirp.

Noisy sound in a phone video

Street or wind wash covers what someone says on camera. Enhance the audio in the video and download an MP4 with the same picture.

Why choose EraseNoise as your audio enhancer

You hear the enhanced voice before you pay. There is no equalizer, compressor, or voice changer to learn.

An AI audio enhancer for speech

A speech model lowers the noise and keeps the words. Music mastering and singing belong in a music editor.

Audio and video in one place

Upload a recording or a video. A video comes back as an MP4 with the picture untouched, or as WAV audio.

The same speaker

The audio enhancer does not replace the voice. An enhanced take that sounds like someone else is a failed take.

Controls after you listen

Noise reduction, Volume, and Trim come after the preview, so you set them by ear, not by guessing.

What do the audio enhancer controls change?

Each control changes the file you download. None of them writes a new performance.

Noise reduction and Volume

Noise reduction mixes some original sound back in. Pull it down if the voice turns thin. Volume raises a quiet voice up to twice its level.

Trim

Keep only the part you need. Minutes are still counted for the whole file, so trim before upload when the file is long.

Can I enhance audio in a video?

Yes. The audio enhancer takes a video file and changes only its soundtrack. The frames stay as they were.

Audio: MP3, WAV, M4A, AAC, OGG, Opus, or FLAC

A voice memo, a call, a lesson, or a podcast take. The enhanced audio downloads as WAV.

Video: MP4, MOV, M4V, or WebM

A phone clip, a screen recording, or a vlog. Download an MP4 with the enhanced audio, or the WAV alone. A picture the browser cannot copy needs an H.264 or HEVC export first.

  3. 3

    Set the controls

    Lower Noise reduction if the voice turns thin, raise Volume if it is still quiet, and trim the ends.

  4. 4

    Download WAV or MP4

    Keep the file when the same person is easier to hear. A video can download as MP4 or WAV.

Where an AI audio enhancer helps

A podcast or remote interview

A guest records over a laptop fan. Run the audio enhancer on that track, and keep the WAV when the guest is clearer and still recognizable.

A vlog or phone video

Street noise covers the talking part of a clip. Enhance the audio of the video, then download an MP4 with the same picture for your editor.

A lecture or meeting recording

Room tone hides the speaker at the back. Use the audio enhancer for clarity, then raise Volume so notes and transcripts are easier to take.

When is an audio enhancer the right tool?

Use this audio enhancer when a voice is hard to hear and you want to set the level. If you can name the problem, the matching page may fit better.

Frequently asked questions

What is an AI audio enhancer?

An AI audio enhancer uses a speech model to make a voice easier to hear. On EraseNoise it lowers hiss, hum, fan, and room noise under the voice. Noise reduction, Volume, and Trim then shape the file you download. It does not regenerate the voice or master music.

How do I enhance audio in a video?

Upload the MP4, MOV, M4V, or WebM to the audio enhancer and compare 30 seconds. Choose MP4 video to keep the picture with the enhanced audio, or WAV audio to take the soundtrack alone. The frames are not re-rendered.

Is this audio enhancer free?

The 30-second preview is free: 3 times in 24 hours without an account, and 20 times after you sign in. The full file is billed in whole minutes, rounded up, with a minimum of 1 minute. The upload limit is 2 GB.

What is the difference between audio enhancement and noise removal?

Noise removal lowers one sound you can name, such as wind or traffic. Audio enhancement is broader: the voice should end up clearer and at the right level. This audio enhancer uses the same speech model, then adds the Noise reduction mix, Volume, and Trim.

Will the audio enhancer change the voice?

No. The speaker stays the same person. If the enhanced preview sounds like someone else, or the consonants chirp, lower Noise reduction or do not download it.

Can an audio enhancer fix music or a distorted recording?

No. It does not equalize, compress, or master a song. A voice that clipped because the mic was overloaded stays clipped. Lower the input level on the next take.

Enhance audio on your next recording

Upload one audio or video file to the AI audio enhancer. Keep the download only if the same person is easier to hear.
