FAQ
Are my audio files uploaded to a server?
No. Reading, decoding, merging, encoding, and downloading all happen in your current browser.
Can I merge audio files in different formats?
Yes. The tool normalizes sample rates, channel layouts, and encoding before joining every file in list order.
How do I change the merge order?
Press and drag an audio card to its target position. The order numbers update automatically when you release it.
Why is the merged audio re-encoded?
Input files can use different formats, sample rates, or channels. Re-encoding normalizes them into one compatible file that plays continuously.
