How does the split work?

You set a part length in minutes and the recording is cut into equal pieces of exactly that length, in order. The last part holds whatever remains - a 47-minute file at 10 minutes per part gives four 10-minute parts plus a final 7-minute part. Nothing is dropped.

Are the cuts placed at pauses or silence?

No. Cuts land at exact time marks - every 10 minutes means exactly every 10 minutes - so a part can end mid-word or mid-sentence. If you need a cut at a precise moment instead of equal intervals, trim the file instead.

What format do the parts come back in?

The same one you uploaded: MP3 in gives MP3 parts, WAV gives WAV, FLAC gives FLAC, and M4A or AAC gives M4A. OPUS and WMA uploads come back as MP3 parts, since those containers do not re-cut cleanly.

How is pricing calculated?

A flat 2 credits per uploaded file, no matter how long the recording is or how many parts it produces. Splitting a 3-hour recording costs the same 2 credits as splitting a 20-minute one.

No. No AI model touches your audio - the split is fully deterministic. The same file and part length always produce the same parts.

Yes. The split runs on our own servers, your files are never sent to a third party or used to train a model, and everything is auto-deleted 7 days after the job finishes.

How it works

1Upload one recordingDrop in an audio file up to 500 MB - MP3, M4A, WAV, AAC, FLAC, OGG, OPUS, or WMA - and set how many minutes each part should be.

2We cut it into equal partsThe recording is split at exact time marks into parts of the length you set, with the last part holding the remainder. No AI model touches your audio - the split is fully deterministic.

3Download the partsParts keep your upload's format and name - lecture-part01.mp3, lecture-part02.mp3, and so on. A single part downloads on its own; more come back as one zip.

Who uses this tool

PODCASTING

Under the upload cap

A long episode or raw session splits into parts that fit a host's per-file upload limit without re-encoding tricks.

EDUCATION

Lectures in sittable pieces

A 90-minute lecture becomes 10-minute parts students can work through one at a time instead of scrubbing a single long file.

TEAMS & MEETINGS

Share a call in chat

Meeting audio split into short parts posts straight into Slack, Teams, or WhatsApp, where one big file would be rejected.

JOURNALISM

Interviews in review chunks

Cut a long interview into equal chapters so each reviewer takes a part and nobody hunts through two hours of audio.

LEGAL & COMPLIANCE

Recordings sized for review

Split a long deposition or call recording into fixed-length parts for the case file, so citations point to a part and a moment.

MUSIC & AUDIO

Rehearsals cut for sharing

A full rehearsal recording splits into equal takes you can send to bandmates without shipping the whole session.

SECURITY

Built for sensitive documents

Bank statements, medical files, case records. Security isn't a feature we added - it's the foundation.

Workspaces are isolated per account. Role-based access shows teammates only what they need.

auto_delete

Deleted, not stored

Files are deleted after processing. Everything runs on our own hardware and is never sent to an outside AI service, so your data is never used to train models.
