Frequently Asked Questions
Common questions about merging audio files online.
Are my audio files uploaded to a server?
No. All audio merging uses the Web Audio API and runs entirely in your browser. Your files never leave your device and no data is sent to any server.
What audio formats are supported?
You can upload MP3, WAV, OGG, and AAC files. Files can be different formats — they will all be decoded to raw audio before merging. The output is available as MP3 or WAV.
Can I add silence or fade between tracks?
Yes. You can set a gap duration (in seconds) between each clip for natural pauses, or enable crossfade to blend the end of one clip into the start of the next for seamless transitions.
Is there a limit on the number of files I can merge?
There is no hard limit. You can merge as many audio files as your device's memory allows. Very long recordings at high bitrate may be slow — if you hit performance limits, try splitting the merge into smaller batches.
