Split audio into parts
One long file, several usable ones. Cut every few minutes, into an equal number of parts, or at the gaps — and keep the original quality, because nothing is re-encoded.

Settings appear once you add an audio file.
The last part holds whatever is left over.
All the same length, to the second.
Quiet this long is treated as a break.

Gaps closer together than this are ignored.
Ignored by the lossless formats.
Still going. Your own device is doing this, so a long video or a big batch takes as long as it takes — and none of it is being uploaded.

How to use it
-
Add your files
Drop in the recording. Its length is read on your device, and nothing is sent anywhere.
-
Check the settings
Choose how to cut it: a length for each part, a number of parts, or at the gaps in the sound.
-
Save the result
Press split. Each part is saved with its own numbered name, and several come back together as a ZIP.
Why it doesn’t upload
The long recordings people split are interviews, lessons, therapy sessions and band practice — hours of audio that would take longer to upload than to cut. Here the cut happens where the file already is.
How to check for yourselfWorth knowing
- Keeping the original format copies the audio across, so the parts are identical in quality to the source. Choosing a different format re-encodes them, which costs a little quality on lossy formats.
- Cuts land on the nearest frame boundary, which is a few hundredths of a second. That is inaudible in speech and music, but it is not sample-exact for editing work.
- Gap mode cuts in the middle of each silence, so no part starts or ends with a clipped word. It cannot tell a dramatic pause from the end of a track.
- Uses the FFmpeg engine, a one-time 31 MB download.
Which way to cut
Every few minutes is for size limits: pick a length that lands each part under whatever you are sending it through. Into equal parts is for a fixed number of files, like four parts for four editors.
At the gaps is for recordings with natural breaks — a set of songs, a list of takes, a conversation with pauses between answers. It listens for a stretch quieter than the threshold that lasts longer than your gap setting, and cuts in the middle of it, so nothing is clipped off either side. If you get too many parts, raise the gap; too few, lower it or pick a quieter threshold.
Questions
How do I split an audio file into parts?
Add the file, choose Every few minutes and set the length — 5 minutes suits most uploads — then press split. Each part downloads on its own, or all of them together as a ZIP.
Does splitting lose quality?
No, as long as you leave the format on “Same format as the original”. The frames between two times are copied into a new file, exactly as they were. Only picking a different format re-encodes the audio.
How do I split a recording into one file per song or speaker?
Use At the gaps. The tool listens for quiet that lasts longer than your gap setting and cuts in the middle of it. For live music raise the gap to 2–3 seconds; for a conversation, 1 second is usually enough.
My file is too big for WhatsApp or email. How many parts do I need?
Divide the file size by the limit and round up: a 90 MB recording for a 25 MB email limit needs four parts. Or compress it instead — Normalize Loudness and the Audio Converter at 96 kbps will usually shrink speech far enough to send in one piece.
Can I split a video the same way?
Not here yet. Pull the sound out first with Extract Audio and split that, or use Split a Video when it is ready.
Why is the last part shorter?
In minutes mode the parts are the length you asked for and the remainder goes into the last one. If you want them all the same length, use Into equal parts instead.
