AudioKit 4 min read Merging

You've got a folder of separate audio files and you need them as one. Maybe it's the parts of a podcast episode, a few takes you want back to back, or an intro, a track and an outro. Merging is the simplest job in audio — join them end to end — but it's easy to end up with the wrong order, an abrupt jump between files, or a re-encoded file that lost quality. Here's how to do it cleanly.

Merging vs making a medley

It's worth knowing which job you actually have. Merging joins files end to end into one continuous track, with an optional crossfade — it's the quick way to concatenate audio, and it keeps each file as-is. A medley is more produced: you trim each track, crossfade every transition, preview them, and normalise the whole thing to a target loudness so it plays as one polished mix. If you just need files stitched together, merge. If you want songs blended into a seamless DJ-style mix, that's the medley maker.

Turn on the crossfade for music. A hard join is fine for spoken word, but between songs a short crossfade smooths the seam so one file doesn't slam into the next. For a fully blended result, step up to the medley maker.

5 times merging audio is exactly what you need

1. Assembling a podcast episode

Join the intro, the main recording and the outro into one file, in order, ready to publish.

2. Stitching takes back to back

Put several recorded takes or sections into a single continuous file so you can listen through without juggling clips.

3. Bundling an EP into one preview

Chain your tracks into a single continuous file for a quick listen-through, a private link or a demo reel.

4. Combining voice notes or memos

Merge a string of voice memos into one file to send, archive or transcribe in a single pass.

5. Building a continuous backing file

Join sections in the right order to make one long backing track for practice, rehearsal or a set.

FAQ

What's the difference between merging and making a medley?

Merging joins files end to end into one continuous track, with an optional crossfade between them — it's the simple way to concatenate audio. A medley is more produced: you trim each track, crossfade the transitions, preview each one and normalise the whole thing to a target loudness. Use merge to stitch files together; use the medley maker to blend songs into a seamless mix.

Can I choose the order of the files?

Yes. Drag the files into the order you want before merging — the final track plays them top to bottom. You can add as many files as you like and reorder them freely.

Can I merge files of different formats?

Yes. AudioKit accepts MP3, WAV, FLAC, AIFF, OGG and M4A together, and you choose the output format for the merged file. Everything is processed in your browser, so nothing is uploaded.
