You recorded a podcast in three takes. Or you have a dozen voice notes that belong together as one recording. Or you split a long track to edit each part and now need them back as a single file. Merging is how you turn a pile of separate clips into one continuous track.
The short version: add your files, drag them into the order you want, and export one file. The merge tool joins them on your device, so nothing uploads and there is no limit on how many you add.
How do I join audio files together?
Add the clips, put them in the right order, then merge and download a single file. The order you set is the order they play in the result, end to end with no gaps unless you want them.
- Add your tracks. Drop in two or more audio files. They list in the order you add them.
- Put them in order. Move tracks up or down so they play in the right sequence, and remove any you added by mistake.
- Merge and download. Join everything into one continuous file and save it as MP3 or WAV.
When you reach for merging
- Podcast segments. An intro, the main conversation, and an outro recorded separately, joined into one episode.
- Voice notes. A run of short recordings that together make one message or log.
- Song parts. Verse, chorus and bridge captured separately, stitched into a full take.
- Audiobook chapters. Several files combined into one long listen for a single download.
- Rejoining a split file. Parts you separated for editing, put back together.
Getting the order right
Order is the thing people get wrong, because files often add in whatever sequence your file picker hands them over, which is rarely the order you want. Before merging, look at the list and use the up and down controls to arrange it: intro first, outro last, takes in sequence.
Then preview the merged result before you download. A quick listen catches a track in the wrong place far more reliably than reading filenames, especially when the files are named something unhelpful like rec_0034. Fix the order, preview again, and only then export.
Mixing formats and the clean-join question
You do not need every file in the same format. You can drop in an MP3, a WAV and an M4A together, and they are decoded and joined into one track, which you export as MP3 or WAV.
One thing to know for the smoothest result: files that share a sample rate join most cleanly. If your clips came from different sources at different sample rates, the join still works, but matching sources sound the most seamless. If you are recording the parts yourself, recording them all in one session or one app keeps the settings consistent and the merge tidy.
Export format
Choose your output based on what happens next:
- MP3 for a shareable, smaller file, ideal for a finished podcast episode or a track you are sending to someone.
- WAV for a lossless join, best when the merged file is going into another editor for more work.
If your clips need trimming before they join, do that first so you are not merging silence and stumbles. The trim tool handles quick cuts.
Why nothing gets uploaded
Every file is read and joined on your own device, with nothing sent to a server. That keeps private recordings private, whether they are confidential interviews or unreleased music. It also means there is no cap on how many files you merge or how large they are; you are limited only by what your device can comfortably hold, not by an upload limit or a paywall.
When your tracks are in order and the preview sounds right, open the merge tool and export the combined file. For edits to the individual pieces before they join, the full audio editor gives you fades, level changes and clean-up.
