Merge Audio
Join two or more audio files into a single clip, in the order you choose.
How it works
- 1
Drop all the audio files you want to join — they stay on your device.
- 2
Arrange them in the order you want using the file list.
- 3
Merge and download the combined WAV.
Questions
Do the files need to have the same sample rate or number of channels?
No. Files with different sample rates or channel counts are automatically normalised to match the first file before merging. The result shows which files were adjusted.
What order will the clips appear in?
The clips are joined in the order the files appear in the list after you drop them.
Does anything get uploaded?
No. All decoding and merging runs inside your browser. The files never leave your device.
Why is the output a WAV?
WAV lets the browser write the result directly without a third-party encoder. The quality matches the original decoded audio exactly.
