What does an audio splitter do?

It cuts one audio file into several files. You decide where the cuts land, and the original audio stream is copied - not re-encoded - so quality stays exactly the same.

How do I split an MP3 into multiple files?

Load the MP3, place a start/end marker pair at each break, then export once. You don't have to cut, download, re-open and repeat.

Can I split an audio file into more than two parts?

Yes. Every marker pair becomes one clip, and all of them are exported together - 10 pages means 10 clips in a single export.

Do splitters affect audio quality?

No. MP3 and AAC are cut on frame boundaries, WAV by byte range and M4A on sample boundaries - all container-level copies. FLAC and OGG are decoded first, which is lossless too.

Do I need to upload my file or install anything?

No. Everything runs in your browser: your audio is never uploaded, and there is nothing to install.

Is there a file size limit?

MP3, WAV, M4A and AAC have no fixed limit. FLAC and OGG must be decoded first, which caps them at roughly 2 hours in a browser tab.

Can I export the timestamps or chapters?

Yes. Save your markers as a CUE sheet or a chapters file (both Pro exports) instead of losing them after the export.

Is this the same as separating vocals from a song?

No. Stem separation pulls vocals or instruments out of a mix. This tool cuts one recording into clips - it does not separate voices or instruments, and it is not a music or stem separator.

Does an audio splitter need hardware, like an HDMI or headphone splitter?

No. Hardware splitters send one signal to several outputs - that is a different product. This audio splitter is software that runs in your browser: it cuts one audio file into several files, and no cable, box or adapter is involved.

What an audio splitter does

Split one audio file into as many separate clips as you want - right in your browser. Leave the audio untouched, place a marker pair wherever a clip should start and end, then export every piece in one go. No upload, no signup, no watermark.

How to split an audio file

01
Load your file
MP3, WAV, M4A or AAC. It opens instantly in your browser; nothing is uploaded to a server.
02
Mark where it splits
Click the waveform to place a start/end marker pair at each break. Add as many as you need: 10 pages, 10 clips.
03
Export all clips
Download every piece at once, or save your markers as a CUE sheet / chapter file (a Pro export).

Why this audio splitter is different

Cut into as many parts as you want, in one pass

Most splitters give you one cut - or chop the file into equal lengths. Here you define every boundary yourself and export all the clips together.

Split where the content splits, not the clock

Chapters, pages, scenes, questions - cut at the moment the content changes.

Check every boundary before you export

Click a marker to jump the playhead to it, then play across the boundary, so you know each cut is right before you export.

Markers you can keep

Export the timestamps as a CUE sheet or chapters file instead of losing them.

Your file never leaves your device

Everything runs locally in your browser.
