Audio Merger

Stitch voice takes, songs or podcast segments into one continuous file. Put them in order, decide how they meet, and export a single MP3 or WAV.

Using the Audio Merger

1

2

Arrange and blend

Move tracks up or down, then pick a crossfade or a short gap between them.

3

Join and export

Press merge, listen to the result in the player and save it as MP3 or WAV.

Choose how tracks meet

Audio Merger Questions & Answers

Can I mix different formats?
Yes. MP3, WAV, M4A, OGG and other files can be merged in the same project.
Do files with different volumes sound uneven?
They can. Run quiet parts through the Audio Loudness Booster first so the whole track has a steady level.
Is there a maximum length?
The limit is your device memory. Several hours of audio usually work fine on a computer.
Are my recordings uploaded?
No. Everything is decoded and joined inside your browser.

Joining Audio Files Without Awkward Jumps

Merging audio sounds simple, but the joins are where listeners notice problems: a sudden jump in volume, a hard cut in the middle of a breath, or a long silence. A good audio merger lets you control each of those.

Order first

Arrange the files before you think about transitions. For podcasts, that usually means intro, segments, outro. For a mix, it means a sensible flow of tempo and mood.

Pick the transition

Spoken content sounds best with a short pause, which gives listeners a moment to reset. Music sounds best with a crossfade, where one track fades out while the next fades in.

Level the volume

Recordings from different microphones are rarely equally loud. Normalise them with the Audio Loudness Booster before merging, and clean noisy takes with the Background Noise Remover. If one file needs trimming, do it in the MP3 Cutter first.
