Split an Audio File
Cut a long recording into parts at equal intervals or at exact times you specify. Download each piece individually or all of them together as a ZIP.
The conversion engine (about 32 MB) loads once on your first run and starts instantly from cache afterwards.
Two ways to split
Equal intervals cuts every N seconds — enter 600 to get ten-minute chunks, which suits long meetings and lectures. Split at times takes a list of positions such as "1:30, 4:05, 12:00", separated by commas or line breaks, when you want the cuts to follow the content.
Download everything as a ZIP
Each part gets its own download link, and one button packages them all into a ZIP. The archive is built in the browser too, so no part of your audio is ever transmitted. File names keep the original name with a sequence number appended.
Typical uses
Breaking a two-hour lecture into chapters, separating a meeting by agenda item, cutting an audiobook into listenable lengths, or lifting individual tracks out of a DJ mix. If you are unsure where the seams are, the silence remover can help you spot them first.
Frequently asked questions
Does splitting reduce quality?
Not if you export WAV. MP3 and M4A are re-encoded, but at 192 kbps or above the difference is very hard to hear.
How many pieces can I create?
There is no fixed limit, though more pieces means more time and memory. Around 100 parts still runs comfortably.
How do I write the split times?
Any of "90", "1:30", "1:30.5" or "00:01:30,500" works. Separate several with commas or line breaks — they are sorted for you.
