Audio Splitter

Break a long recording into equal parts, fixed-length chunks, or pieces divided at the natural pauses — then take them all in one zip.

About this audio splitter

The Audio Splitter breaks one long file into several shorter ones — by count, by length, or at the natural pauses in the recording.

Equal parts divides the file into however many pieces you ask for, all the same length. Fixed length chops it into chunks of a set duration — useful when something you are uploading to has a per-file time limit. At silences looks for pauses long enough to count as a break and cuts there, which on a recording of several separate takes or songs usually lands on exactly the right spots.

The plan updates live as you change the settings, so you can see how many parts you will get before committing. Every part gets a ten-millisecond fade at each edge to avoid clicks, is exported in your chosen format, and the whole set comes down as a single zip — with individual download buttons in the list if you only want one.

How to use
  1. Upload the long audio file.
  2. Choose equal parts, fixed length, or splitting at silences.
  3. Adjust the setting until the preview line shows the number of parts you want.
  4. Pick WAV or MP3, then press Split audio.
  5. Download everything as a zip, or grab individual parts from the list.
FAQ

They are bundled into one zip file you download in a single click. Each part is also listed with its own download button if you only want a few.

It finds every stretch quieter than the threshold that lasts at least the minimum length, then cuts in the middle of each one — so both sides keep a little of the pause and nothing starts abruptly.

Up to two hundred. Beyond that the zipping becomes slow and the result is rarely what anyone wants; use fixed-length chunks with a longer duration instead.

No. They are end to end, and together they add up to the original file exactly. A tiny fade is applied at each edge purely to avoid clicks.

MP3 if you are sending them anywhere — the zip will be a fraction of the size. WAV if the parts are going into an editor for further work.
