Questions
What happens to my recording?+
It is sent over an encrypted connection to our cleaning server, cleaned, and sent back. It is deleted as soon as you have the result, and never kept, shared or used for anything else.
What is the difference between Fast and Studio?+
Fast uses one AI model trained to tell speech from noise, and is ready in seconds. Studio first lifts the voice away from everything else with a second, much larger model, then polishes it with the first. It removes music, crowds and wind that Fast leaves behind, and takes longer.
What does the 0 to 100 slider do?+
100 removes all the noise it can. Lower numbers keep a little of the room in, which can sound more natural on a voice that was recorded far from the microphone.
Does it work on music?+
It is made for speech: podcasts, interviews, voice notes, lectures and video voice-overs. Studio will take music away from behind a voice, so on a song it keeps only the singing.
How long can the recording be?+
Up to one hour with Fast, and up to five minutes with Studio. For a longer recording, cut it into parts.
Is it free?+
Yes, with no sign-up, no limit on how many files and no watermark.
