In what order are my files joined?

Upload order. The first file you add plays first, the second follows it, and so on - nothing is reordered, trimmed, or dropped. If the order matters, add the files in the sequence you want to hear them.

Can I mix different formats in one merge?

Yes. Any mix of MP3, WAV, M4A, AAC, FLAC, OGG, OPUS, and WMA can go into the same merge. Every input is decoded and re-encoded to the one output format you pick, so mismatched sources come out as a single clean file.

No. No AI model touches your audio - the merge is fully deterministic. The same inputs in the same order always produce the same output.

Does merging change the sound?

The clips are joined back to back with no crossfades, gaps, or volume changes. The output is re-encoded to your chosen format: WAV is lossless, while MP3 and M4A are compressed, so keep your originals if you may need them again.

How is pricing calculated?

Merging is 1 credit per uploaded file, with a 2-credit minimum - which a merge always meets, since it takes at least two files. Merging five clips is 5 credits.

Yes. The merge 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 your clips in orderDrop in two or more audio files - voice memos, episode parts, interview sides - in the sequence you want to hear them. Mixed source formats are fine.

2We join them into one fileEvery clip is decoded, aligned to a common shape, and joined back to back in upload order, then re-encoded to the format you picked. No AI model touches your audio - the merge is fully deterministic.

3Download the merged fileOne continuous audio file named after your first clip - intro.mp3 plus more parts comes back as intro-merged.mp3.

Who uses this tool

VOICE NOTES

Scattered memos, one recording

Record a thought in three separate voice memos and merge them into one file you can play, share, or transcribe in a single pass.

PODCASTING

Episode parts into one episode

Join the intro, the interview, and the outro into a single file ready for your host, instead of stitching them in an editor.

JOURNALISM

Interview sides rejoined

A double-ender or an interview split across takes becomes one continuous recording to review and pull quotes from.

EDUCATION

Lecture halves back together

A class recorded in two parts around a break merges into one file students can play start to finish.

MUSIC & AUDIO

Takes and bounces in sequence

Line up session bounces or rehearsal takes back to back into a single reference file to listen through.

LEGAL & COMPLIANCE

Call segments as one exhibit

A call recording exported in segments merges into one continuous file for the case or matter file.

SECURITY

Built for sensitive documents

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

lock

Encrypted in transit

Encrypted in transit over TLS 1.2+, and stored in access-controlled, encrypted object storage. Files are protected the moment they leave your browser.

admin_panel_settings

Your files stay yours

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.
