A recording that sounds muddy is usually a recording with a room behind it.
Drop it in and the background is pulled down so the voice sits in front, where it belongs. This voice cleaner ai model is a voice cleaner online free tool that needs no install, whether the file is a phone recording or a studio one.

The cleaned file is the free file. No watermark, no trial length, no account — files up to 45 minutes. A pass adds loudness levelling and a heavier repair pass for rough recordings. That's a voice cleaner free of any daily fee, on every device.
Not every upload makes it through cleanup, and it's worth being upfront about why. In the 31 days to 21 August, CleanGrab rejected 15 uploads and only 1 failed outright once processing had started — most problems get caught before cleanup even begins, at the file check. The single largest rejection reason on record was simply a file over the 1 GB limit, logged 3 times in that period; runs that get past that check almost always finish cleanly. That 15-and-1 split matters because it means the model itself is reliable once a file is accepted — the thing worth worrying about is uploading something already too big or too long, not the cleanup silently making a recording worse. It also means the size and length limits are doing their job as a filter, not a wall — they catch what genuinely can't be processed and let everything else straight through. We'd rather publish that small, honest split than bury it because it doesn't sound impressive.
Clarity is mostly a contrast problem. Your voice was always there; it is competing with a fan, a street, a laptop, the hum of the room. Pull that layer down and the same recording reads as sharper, closer and easier to listen to — without touching the voice itself. What comes back is a voice clear of the room it was recorded in, not a different voice; that's how to improve voice quality without re-recording anything.
That is the honest scope of this page: it is the same model as the rest of the site, aimed at the question people actually ask. It does not add detail that was never recorded, it does not raise a whisper into a broadcast voice, and it will not rescue a clipped or distorted file.
Just want the short version? See enhance speech online for the same tool without the explanation. For a clip with picture as well as sound, the same model handles video too — the room gets pulled down, the voice stays as recorded. It's built for speech specifically, not everything: music and other non-speech sound are treated differently, sometimes suppressed clumsily rather than cleanly removed.
This page runs as a straightforward audio cleaner — one upload box, three strengths. A trained model does the work instead of a fixed EQ: audio cleaner ai, or flipped, ai audio cleaner. The same model doubles as an ai voice cleaner, tuned for speech over music.
The free tier is audio cleaner free, with no clean up audio free paywall and no locked free audio cleaner trial — no watermark, no account, ten uploads a day. Running entirely online makes it audio cleaner online free, or just audio cleaner online, the same from a phone or a laptop. Voice cleaner ai free and clean audio ai free are that one identical tier.
The page starts on Balanced, which keeps voices sounding like themselves. Two exceptions worth knowing: if the recording is hollow and echoey rather than noisy, the room echo page starts on Strong, which is the setting that actually reaches the echo tail. And if the voice starts sounding processed or swallowed, step back to Gentle — over-cleaning is the most common way to make a recording worse.
Heavy room echo and reverb are a harder, separate problem: CleanGrab reduces light echo, but it will not fully erase a very reverberant room. We'd rather say that plainly than promise something the tool can't do.
CleanGrab is tuned for voice and speech — podcasts, interviews, calls, voice memos, lectures. On music or other non-speech audio the result can be poor, and the tool will tell you when it couldn't detect clear speech instead of handing you a mangled file. It's tuned for one voice at a time, not a full mixed episode — handy for podcasters cleaning up a single speaker.
Clean audio online free is this same page, no session limit beyond the daily cap. Audio cleaner ai free and ai audio cleaner free are that identical tier, not a locked preview. For a thin voice the goal is clear voice ai output, not just louder — clarity and volume are different fixes.
The free AI audio cleaner is the tool above: pick a strength, compare before and after in the browser, download. There is no separate free tier or extra cleanup step; that is the whole process.
Call it an ai sound cleaner: it treats music differently from speech, which is what it's tuned for. To ai clean audio you just need the file — no manual noise sample, no calibration. Unlike some audio AI tools, it asks for no manual noise sample. That's clean audio ai. This ai audio cleaner free version keeps the same caps as every other page, and running video through counts as audio clean up ai too — picture untouched, sound track cleaned.
This is the classic clean up voice recording job people bring here from a phone. Phone memos are the most common thing dropped in here, and they have a particular problem: the microphone is close to your hand and far from your mouth, so it picks up the room and the handling as loudly as the voice.
There's no cost hidden behind clean up audio here — the free tier is already free. The strength control works like an ai voice clean up dial: further right removes more, but risks thinning the voice, and by default the result stays ai voice clean rather than an aggressive repair. Run an old, hissy file through this mp3 cleaner or a fresh WAV recording — same one-pass cleanup either way, and a short clean up audio ai job takes no more setup than a full lecture.
The same audio cleaning ai model handles a two-minute memo or a forty-five-minute lecture, and the free tier stays audio clean free from upload to download.
Looking for an audio enhancer or a voice enhancer? Same model, with what it can and cannot do spelled out.
Upload it here and let the model pull the background down. The voice stays as it was recorded; what changes is everything behind it, which is what makes a recording read as muddy in the first place.
Not by itself — this separates voice from background rather than boosting level. A voice that was recorded very quietly will sound clearer but still quiet; that is a levelling job, not a cleaning one.
Heavy room echo and reverb are a harder, separate problem: CleanGrab reduces light echo, but it will not fully erase a very reverberant room. We'd rather say that plainly than promise something the tool can't do.
MP3, WAV, M4A, FLAC, OGG, and common video files, up to 45 minutes per upload. You get back a cleaned MP3 (192 kbps) and a lossless WAV.
Yes — no account, no watermark, 10 recordings a day. Adobe Podcast, Krisp and Cleanvoice all limit free usage to push you toward a paid tier. Here the free version cleans recordings up to 45 minutes, ten a day, with no watermark; the optional pass only raises that ceiling, it never lowers it. The ads around the tool cover running our hardware.
Your upload is deleted the moment it's processed and the cleaned file is wiped from the server within 45 minutes. Nothing is shared or used to train anything — see privacy.
Upload the recording to CleanGrab and it pulls the room noise down — fans, traffic, hum and static — leaving the voice in front. The Balanced setting keeps voices sounding natural. No account, 10 recordings a day.
Yes — the same model pulls the room noise out of a video's audio track and leaves your voice as it was recorded; only the audio changes, the picture is never touched.
It separates the voice from steady noise sitting behind it: hum, hiss, fans, air conditioning and traffic. CleanGrab does this free on its own hardware, with no account and no watermark.
Yes, free with no account: 10 recordings a day. Drop in an MP3, WAV, M4A, FLAC, OGG or a common video file and you get a cleaned MP3 and a lossless WAV back. Nothing to download or install on Windows or Mac and no browser extension: it is a web page, the cleaning runs on our own server, and the upload is deleted right after processing and the cleaned file within 45 minutes.
Yes. It doesn't matter whether it's the room, a fan or a cheap mic doing the picking up — drop the recording in and the background gets pulled down the same way as any other file, whether it's a microphone picking up background noise at your desk or a phone memo recorded on the move.
Speech: podcasts, interviews, calls, voice memos, lectures, from a short clip to a full episode, with no minimum length. It pulls down steady background sound such as room tone, hum, hiss, fans and traffic, not just obvious loud noises. On music or other non-speech audio the result can be poor, and the tool tells you when it cannot find clear speech to work with.
The free tier is background noise removal: it removes hum, hiss, fans and traffic and reduces light echo, but a very reverberant room is a harder problem that no echo remover in a browser fully undoes. A paid pass adds loudness levelling and a heavier repair pass on top, which is the closest thing here to an enhancer.
Upload the file and let the model pull the room noise down — the voice stays exactly as recorded, only the background changes.
Run each one on the same strength — picked by hand, since the default is chosen per recording — and every session comes back sounding like the same room.
Clarity and loudness are different jobs — this pulls the background down so the voice reads as closer, though a very quiet voice will still sound quiet.
