Audio Merger FAQ
Are multiple files uploaded to a server?
No. The selected files are decoded and joined in your browser. AudioCutter does not upload your media files.
Do files need the same format?
They can start in different common audio formats, but browser support and encoder availability affect which combinations process successfully.
Why can merging fail?
Merging can fail if the browser cannot decode a file, the device runs out of memory, or files have unsupported audio properties.
Can I use the merged file in editing software?
Yes. WAV is usually best for further editing, while MP3 is usually better when you need a smaller file for sharing.
