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.

你們會把我的檔案上傳到伺服器嗎？+

不會——這裡的每個工具都完全在你的裝置上處理檔案，不會向伺服器上傳任何內容。唯一的例外是 AI 工具，它們會把擷取的文字（而非檔案本身）傳送給 Claude 來完成工作。

有檔案大小限制嗎？+

我們沒有人為設下限制，但由於處理過程在你的瀏覽器中進行，非常大的檔案（超過 500MB 或 1000 頁）會受你裝置記憶體的限制，而非我們的限制。
