FAQ
Common questions
Is my audio uploaded anywhere?
No. Decoding, joining, preview playback, and export all happen locally in your browser.
What audio formats can I upload?
Whatever your browser's built-in audio decoder supports — most browsers handle MP3, WAV, M4A, and OGG. Any file that can't be decoded is reported clearly and skipped rather than silently breaking the join.
What if my files have different sample rates or channel counts?
The output uses the first file's sample rate and channel count. Other files are resampled to match, and mono/stereo are converted as needed — mono is duplicated to both output channels, stereo is downmixed to mono if needed.
Can I reorder files after adding them?
Yes. Use the Up and Down buttons on each file to arrange them in the order you want before joining.
Is there a limit on file size or number of files?
Yes — both are limited to keep the join safe to run in your browser's memory, with a clear message if you go over.
