Join several audio files end to end, with a gap if you need one. The tool is free in your browser and shows the result without asking you to create an account.

How to use

Select several audio files to join; the interface mentions MP3, M4A, OGG, FLAC and WAV as examples.
Check the file order, because the merge follows the sequence shown in the list.
Enter a silence duration in seconds if you want a pause between tracks, or leave it at zero.
Run the merge, listen to the joins and download the combined file.

Example

To assemble audiobook chapters or several interview takes, arrange the files in their final order. A short inserted silence keeps the voices from touching, while listening at each join helps you notice any sudden change in level or tone.

Limits and formats

Merging does not change volume, speed or pitch; it simply places the files one after another.
The combined duration must stay within the total limit shown by the interface, which is 15 minutes.
An inserted silence is real empty audio; it cannot hide an overlap or remove background noise.
Check mono and stereo files before joining, because a mix of channel layouts can sound uneven.

Where processing happens

The join is performed in your browser. The files are read and combined on your device, with no account and no outside transfer.

Frequently asked questions

Can I change the order of the files before merging?

Yes, the order shown in the list becomes the order of the final audio. Remove and re-add a file if it appears in the wrong place, then confirm the sequence before starting the merge.

When should I add a silence between tracks?

Use a short silence when you want a clear break between chapters, songs or speakers. Even a small pause can make the transition feel intentional instead of abrupt, especially in spoken-word recordings.

What if one file is much louder than the others?

This tool does not normalize loudness during the merge. Adjust each source file with a volume tool first, then merge the corrected versions so the final track sounds consistent from start to finish.
