よくある質問 (FAQ)

What format is the downloaded file?

WAV — a universally compatible, uncompressed format. Re-compress it afterward with another tool if you need a smaller MP3-style file.

Can I trim a very long recording?

Yes, though very long files use more memory since the whole file is decoded in your browser — for hour-plus recordings, performance depends on your device.

Is my audio uploaded anywhere?

No. Decoding, trimming, and encoding all happen locally using your browser's built-in Web Audio API.
