Clean up an episode before it goes out — hum, hiss, fans and traffic pulled down while the voice stays natural.
Free, with 10 episodes a day if you're running a whole backlog.

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.
CleanGrab cleans up speech entirely on our own hardware, so there's no per-file fee and no watermark: drop in a recording and get a cleaned voice back as a 192 kbps MP3 plus a lossless WAV. No account, no sign-up, and your upload is deleted the moment it's processed.
One pass takes care of all of that, free every time.
This isn't an editor: no cutting, no chapters, no music bed. Trimming, levelling and arranging segments is a separate step in whatever editor you already use (Audacity, Descript, Reaper). The usual order is record, clean here, then edit — that way the editor gets a cleaner file to work with, not a noisy one.
Recording is the other end of the pipeline this page doesn't cover — you need a mic and a recording app to make the episode in the first place, not a cleanup tool. Once you've got the file, this is where it comes next.
This is where the free noise tools that cap you at an hour of audio a day fall over: a back-catalogue clean-up or a batch of guest interviews can blow past that in one sitting. CleanGrab gives you 10 episodes a day — upload the next one the moment the last finishes. See the limits comparison against Adobe Podcast if you've hit that wall before.
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.
Cleaning up a single recorded call rather than a whole episode? See cleaning up a Zoom or Teams recording. Publishing the episode as a video too? See cleaning audio for a YouTube video.
Once the episode is clean, a transcript is often the next step — for show notes, for accessibility, or just to search back through old episodes. ScribeGrab turns the cleaned recording into a full transcript, or the episode summary tool pulls out the topics and highlights ready to paste into show notes. Want a short moment from the episode for social media? ScribeGrab's podcast clip tool cuts a segment and burns in captions automatically.
The podcast audio cleaner free tier has no watermark and needs no account. The podcast audio cleaner ai model hands back a cleaned MP3 (192 kbps) and a lossless WAV on every episode.
Yes — you get 10 episodes a day, so you can run one after another. The only limit is 2 files processing at once per visitor, which just keeps the queue moving.
Yes, as long as it's one mixed file — it separates the combined voice track from the room behind it. It doesn't isolate one speaker from another on a single track.
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.
Yes: no watermark, no account and no credit card, 10 episodes a day, up to 45 minutes each.
Same job, different tool. Adobe Podcast AI needs an account and caps free use; CleanGrab runs in your browser with no sign-in, 10 episodes a day, and the model runs on our own hardware rather than a third-party AI cloud. Adobe's result can sound very polished; CleanGrab trades a little of that polish for no account.
Yes: an AI audio model trained on speech separates the voice from the noise behind it, on our own hardware. The noise removal does not depend on language; it works on the steady background sound under the voice, whatever language is spoken.
Usually, yes, whether you record by hand or use an AI podcast maker. CleanGrab removes the noise and, with a pass, levels the loudness to the usual podcast target; to edit audio for the finished episode (cuts, chapters) you still need an editor such as Audacity, which is free, Descript, which adds transcript-based editing, or Reaper. Run CleanGrab first: editing goes easier once the hiss is gone.
