Audio recorder FAQ

Will the page request microphone access automatically?

No. The browser only prompts when you click Start recording. Until then the mic is untouched.

Where does the recording go?

It's encoded to MP3 and offered as a download. We don't keep, analyse or index your recording.

Can I record long sessions?

Yes, but very long sessions can use a lot of memory. For sessions longer than an hour, prefer a desktop browser.

Why MP3?

Universal compatibility. We re-encode to MP3 with ID3-friendly metadata so the file plays everywhere.
