ARP: Remove Background Noise

Clean up a noisy recording on your iPhone. The recording never leaves it. A voice memo in a loud café, an interview over traffic, a lecture from the back row: ARP takes the background noise out of speech, on your device, and shows you what it did. HEAR THE DIFFERENCE Switch between Original, Cleaned and Removed. Removed is what the cleanup took out. If you can follow speech in it, the cleanup took too much, and you'll know. READ THE DIFFERENCE Transcribe the original and the cleaned version on your device, then switch between them with the same control you listen with. Copy either one, or export it as text or subtitles (SRT). IT TELLS YOU WHEN NOT TO ARP measures the background level first. If a recording is already clean, it says so, changes nothing, and doesn't count it against your free recordings. LONG RECORDINGS Interviews and lectures up to 3 hours. EXPORT The cleaned recording as M4A, or as 24-bit WAV and AIFF with Premium, at the recording's own sample rate. PRIVATE BY DESIGN Your audio is processed on your device and never uploaded. No account, no analytics, no tracking. The one network request is Apple's speech model, downloaded once the first time you transcribe. PRICING 10 recordings free. Premium is a single purchase: no limit on recordings, plus 24-bit WAV and AIFF export. No subscription. Works on iPhone and iPad with iOS 26 or later. Made in Sydney by Matthew Worner. No account. Pay once. Stays on your device.
