Podcast tracks, voiceovers, lectures, voice memos or the sound of a video.

What the enhancer does to your audio
Four steps that audio engineers apply to almost every voice recording, done for you.
Removes background noise
A speech-trained neural network turns down fans, traffic, hiss and chatter.
Cuts low rumble
An 80 Hz high-pass filter removes handling noise, desk bumps and HVAC rumble.
Levels the loudness
Measures loudness with the ITU-R BS.1770 standard and sets it to -16 LUFS.
Prevents clipping
A soft limiter keeps peaks under -1 dBFS, so louder never means distorted.
Audio enhancer or noise remover?
Use the background noise remover when the level of your recording is already right and you only want the noise gone. Use the enhancer when the recording is also too quiet, uneven between files, or has low rumble: it finishes the voice so it is ready to publish.
-16 LUFS is the loudness most podcast platforms recommend for stereo shows, and it is comfortable for voice on YouTube and social video too.
Private by design
Your recording stays on your device
Most online audio cleaners upload your file to a server. Clean Audio downloads its noise model to your browser once and does all the work locally, so interviews, meetings and unreleased episodes never leave your computer or phone.
That also means no upload wait, no queue and no file stored on someone else's server. Close the tab and the file is gone.
Frequently asked questions
What does an AI audio enhancer do?
It improves speech recordings automatically. Clean Audio's enhancer removes background noise with a neural network, filters out low rumble, sets the loudness to -16 LUFS and keeps peaks from clipping.
Is it free?
Yes. The enhancer runs in your browser for free, with no sign-up, no watermark and no upload.
Is it an alternative to Adobe Podcast Enhance?
It solves a similar problem for noisy speech. The difference is that Clean Audio works on your device, so you don't upload your recording, and it also handles video files.
Can it enhance music?
No. The model is made for speech and will treat instruments as noise. Use it on voice recordings, podcasts and the sound of talking videos.
Which file formats are supported?
Audio: MP3, WAV, M4A, AAC, FLAC, OGG and Opus. Video: MP4, MOV, M4V, WebM and MKV. You can download clean audio as MP3 or WAV, and videos come back as MP4 (or WebM for WebM files).
Is there a length or size limit?
Files up to 30 minutes and 2 GB can be cleaned in the browser. The first time you use the tool it downloads a 12 MB noise model, which your browser keeps for later visits. Longer files work best on a laptop or desktop.
Is my file uploaded anywhere?
Not by the free tool. Clean Audio downloads its noise model to your browser once and cleans the file on your own device. Only if you choose Studio is the audio sent to our cloud for that one job, and the upload is deleted within a day.
