Great picture, terrible sound? Import the video and Voice Isolation hands it back with the noise gone — same footage, same length, clean voice. Most clips come back in about a minute. No desktop session, no re-syncing an audio file to your timeline. It works the same way on plain audio: voice memos, interviews, dictation, or anything you can share in from another app. ▸ WHAT IT FIXES • Wind on outdoor and beach clips • Café and restaurant chatter • Traffic and street noise • Room echo and reverb • HVAC hum, fan noise, and other steady backgrounds ▸ HOW IT WORKS Pick a video or an audio file. Voice Isolation pulls out the audio, runs it through an AI speech-enhancement model, and blends the result back against your original. For video it remuxes the cleaned audio onto your footage automatically, so what you get is a finished MP4 — not an audio file you have to line up yourself. One tap A/B: switch between the original and the cleaned version and hear exactly what changed before you export anything. Cleaning runs on our servers, so your clip is uploaded over an encrypted connection while it is processed. Uploads are deleted automatically within 48 hours, and we never train on your audio. ▸ BRING IT IN • Record in the app with a live level meter • Import audio (M4A, WAV, MP3) or video (MP4, MOV) from Files • Pull videos straight from your Photo Library • Send anything in from another app through the iOS share sheet ▸ GET IT BACK OUT • Share the cleaned audio to any app • Save the cleaned video as a new MP4 (Pro) • Export as WAV (Pro) • Save to Files or Photos ▸ FREE • 3 cleans a day, clips up to 60 seconds • Audio and video draw on the same 3 — video is not walled off • Watch the cleaned video in the app; saving it out is Pro • Full A/B preview, player, and cleaned-audio sharing • Ad-supported ▸ PRO • No daily limit — clips up to 10 minutes, and 90 minutes of cleaning a month • Save the cleaned video out as a new MP4 • WAV export • Adjustable cleaning strength, so you can dial back how aggressive it gets • Re-clean up to 10 saved clips in one batch • Share Extension — clean audio straight from the share sheet, processed entirely on your iPhone with nothing uploaded • Zero ads ▸ SUBSCRIPTION Voice Isolation Pro Monthly — $7.99 per month Annual — $39.99 per year, including a 7-day free trial Payment is charged to your Apple ID at confirmation of purchase.
