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.

Questions

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.
