Edit, clean and convert audio.
Your files never leave your device.
A full audio editor that runs in your browser. Cut out the coughs, remove the hiss, level the volume, join the pieces, save as MP3 or WAV. Free, no signup, nothing uploaded.
✂ Trim and cut
Delete a cough, a pause or a fumbled sentence and stitch the sides back together with no click at the seam.
Trim audio →✧ Remove noise
Learn the room tone and filter out fans, hiss and hum across the whole recording, up to 34 dB of it.
Clean a recording →≡ Fix quiet audio
Bring every spoken passage to one steady loudness, so nobody rides the volume knob while listening.
Level the volume →⇥ Join files
Merge recordings end to end with gaps, silence blocks or crossfades, and matched loudness across pieces.
Join audio →⇄ Convert formats
Turn anything your browser can read into MP3 or WAV, at the sample rate and bitrate you choose.
Convert audio →☏ AMR voice memos
Phone call recordings and voice memos in .amr open, play and convert here. Few browser tools can.
Convert AMR →Why it is private by design
Most online audio tools upload your file to a server, process it there, and let you download the result. TidyAudio does not have a server to upload to. The whole editor is delivered to your browser as a page, and from then on your device does the work: decoding, editing, noise removal, encoding. That is not a policy promise you have to trust, it is how the software is built. It also means there is no queue, no file size tier and no waiting for an upload on hotel wifi.
What is inside
- A real editor: waveform view with zoom, selections, cut and stitch with seamless joins, fades, undo across every operation.
- Noise cleanup: a proper spectral filter that learns your room tone, with light, medium and strong settings.
- Volume levelling: every spoken passage brought to a target loudness without the pumping of a naive compressor.
- Music beds: lay music under a voice with automatic ducking, so the bed drops while you speak and returns in the gaps.
- Joining: order pieces by drag, set gaps or long silences, match levels across recordings, crossfade the joins.
- Conversion: export as WAV or MP3 at your choice of bitrate, sample rate and channels, including from AMR voice memos.
Common questions
Is TidyAudio really free?
Yes. Every feature is free, with no signup, no watermark and no artificial limits. The site is supported by unobtrusive ads.
Are my files uploaded anywhere?
No. All processing happens in your browser on your own device. The only things fetched from the internet are the page itself and, on first use, the MP3 encoder and AMR decoder libraries, which are code, not your audio.
Which formats are supported?
Reading: WAV, MP3, M4A, OGG, FLAC and anything else your browser can decode, plus AMR voice memos. Writing: WAV (lossless) and MP3 at 96 to 320 kbps.
Does it work offline?
Mostly, yes. Once the page is loaded, editing and WAV export work with no connection. MP3 export and AMR decoding each fetch their codec once, then they are cached.
Can I use it on my phone?
Yes. The layout adapts to small screens. Very long recordings are more comfortable on a desktop because audio takes roughly 10 MB of memory per stereo minute.
