- No sign-up, no watermarks, no daily quotas
- Free, with no limit on how often you use it
How it works
Long recordings run into limits: an upload cap, an attachment size, a transcription service that only takes ten minutes at a time. Splitting is the fix, and doing it to a two-hour interview by hand is nobody's idea of an afternoon.
Two ways to divide
Fixed length is what limits need — five minutes each, say, with the last piece shorter. Equal parts is for dividing a recording into a set number of roughly equal chunks, such as sides of a tape or sections of a lecture.
Each piece stands alone
Every part is a complete, playable MP3, numbered in order. Nothing needs reassembling and the sequence is unambiguous.
Cuts fall where you set them
Pieces are re-encoded rather than copied, so each starts exactly on time. Copying would snap the cuts to frame boundaries, which drifts over a long file.
Limits
Up to twenty pieces at a time, and the file's length has to be readable by your browser — which is true of MP3, WAV, M4A and OGG, and not always of more obscure formats.
Split an audio file — questions
Can I split into ten-minute pieces?
Yes. Choose to split by length and set 600 seconds.
Is each piece playable on its own?
Yes. Every part is a complete MP3.
How many pieces can it make?
Up to twenty at a time.
Is my recording uploaded?
No. The splitting runs in your browser.
