如何 Merge Audio

1
Add your files
Drop in two or more audio files — they're decoded in your browser.
2
Set the order and gap
Reorder the list and choose an optional silent gap between tracks.
3
Merge and download
Click Merge & download to save the joined file as MP3 or WAV.

Do the files need to be the same format?+

No. Each file is decoded independently and resampled to a common rate, so you can mix MP3, WAV, M4A and more.

Is anything uploaded?+

No — every file is decoded and the merge is done in your browser.

Can I add a gap between tracks?+

Yes — a slider adds up to 5 seconds of silence between each file.

What order are they joined in?+

The order in the list — use the up/down arrows to rearrange before merging.

你们会把我的文件上传到服务器吗？+

不会——这里的每个工具都完全在你的设备上处理文件，不会向服务器上传任何内容。唯一的例外是 AI 工具，它们会把提取的文本（而非文件本身）发送给 Claude 来完成工作。

有文件大小限制吗？+

我们没有人为设置限制，但由于处理过程在你的浏览器中进行，非常大的文件（超过 500MB 或 1000 页）会受到你设备内存的限制，而非我们的限制。
