Split one recording.
Never leave your browser.
Got a 20-minute meeting recording but your free transcriber only handles 10-minute clips? Drop in a file, split it by hand, on a fixed interval, or into equal parts, and download every piece as a WAV. Nothing is uploaded anywhere.
Split an audio file
Checking local library…
Load a file to start splitting.
Segments will appear here once you load a file and add split markers.
Drop an audio file or open one from your local library to start splitting.
Splitting a recording shouldn't require an upload
Most online splitters work by uploading your file to a server, cutting it there, and emailing you a link to the pieces. This one keeps every step — decode, mark, cut, encode — on your device.
Your file never leaves your browser
Decoding and splitting happen with the Web Audio API in this tab, nothing else.
The ZIP is built locally too
A small hand-rolled ZIP writer packages your segments in-browser — no upload step to produce a download link.
Downloads and saves are explicit
Download segments, download a ZIP, or save to your local library when you choose to. Nothing else happens automatically.
Three ways to split
Use whichever fits the job — hand-placed markers, a fixed interval, or an exact number of equal parts. All three can be combined.
- 1
Load your audio
Drop a file, choose one from disk, or open a take saved by the voice recorder.
- 2
Add split markers
Click the waveform by hand, or use "every X minutes" / "into N parts" to set them all at once.
- 3
Export the pieces
Preview, download, or save each segment individually, or grab everything as one ZIP.
A few reasons people split audio files
Fitting a meeting into the free transcriber
A 20-minute meeting recording is longer than the free transcribe tool's 10-minute cap. Split it into 10-minute chunks first — the preset chip sets this up in one click — then transcribe each piece.
Breaking a long lecture into topics
Drop markers where the subject changes and export each part separately, so listeners can jump straight to the section they need.
Turning one take into equal clips
Use "into N equal parts" to divide a long ambient or music recording into evenly sized files for editing or distribution.
Isolating a moment from a long capture
If you only need to trim a single range instead of splitting the whole file into pieces, the audio trimmer is the better fit.
Trim, merge, and transcribe too — all local
Need to cut a single range instead of splitting into pieces? Use the free audio trimmer. Need to put pieces back together? Try the audio merger. Once your pieces are ready, the transcribe tool turns each one into text — still no upload. Not sure how long each piece needs to be? The duration calculator checks in an instant. Trimming, splitting, and merging in one job? The Audio Studio puts it all on one timeline instead of juggling separate tools.
Audio splitter FAQ
What audio formats can I split?
Anything your browser can decode: WAV, MP3, M4A, AAC, FLAC, OGG, Opus, WebM, and the audio track of common video containers. If a file will not decode, you get a friendly error and can try another one.
Is my audio uploaded anywhere?
No. The file is decoded and split with the Web Audio API right in this browser tab. Nothing is sent to a server, whether you drop in a file or open a take from your local library.
How does "Every X minutes" work?
It drops a split marker at every interval you set — for example every 10 minutes — so a long recording becomes a run of equal-length chunks. The last chunk keeps whatever is left over.
Why would I split into 10-minute chunks specifically?
The free transcribe tool caps clips at 10 minutes per pass. If you have a 20 or 30-minute meeting recording, split it into 10-minute pieces first, then transcribe each piece — still without uploading anything.
Can I fine-tune the split points by hand?
Yes. Click anywhere on the waveform to drop a marker, drag an existing marker to adjust it, or click the small × on a marker to remove it — on top of or instead of the auto-split options.
How do I get all the pieces at once?
"Download all" packages every segment into a single ZIP file built right in your browser. "Save all to library" stores every segment locally so you can open them later in the trimmer, merger, or transcribe tool.
