Perfect Sound

New in 2.1: a fresh Liquid Glass look on iOS 26 and later. Remove traffic, hum, hiss and wind from your videos with on-device AI and hear the difference in seconds.

Bad sound ruins good videos. Perfect Sound fixes it – right on your iPhone or iPad.

Pick what bothers you – traffic, hum, hiss, wind, crackle – and hear the difference in seconds. Hold one button to compare with the original. When you need more control, open the spectrogram workbench and repair section by section.

CLEAN UP A RECORDING IN SECONDS • Choose the problem: matching filters are preset and the preview starts right away • Hold to hear the original, release for the cleaned version • Adjust the strength, clean the full take and export

AI VOICE ISOLATION – ON DEVICE • Separates speech from traffic, crowds and room noise • Runs entirely on your iPhone or iPad – nothing is uploaded

FIX WHAT BOTHERS YOU • Hum and electrical buzz, hiss and noise floor, wind and rumble • Handling noise, coughs, audience noise, applause • Clicks, crackle and dropouts, clipping and distortion • Too dull, too harsh, too quiet, too much reverb

PRO TOOLS WHEN YOU NEED THEM • Interactive spectrogram with section-by-section repairs • Repair mix: blend original and repaired sound live • Editor repair: replace a bad passage with a clean one from another take, with crossfades • EQ and reverb for the final polish

SUBTITLES • Transcribe speech on device, edit and translate subtitles • Export SRT or burn subtitles into your video • Fix voice: re-record a wrong word while the background stays intact

IMPORT & EXPORT • Import from Photos or Files: MP4, MOV, M4A, WAV, MP3 and more • Export your video with the repaired sound in sync with the picture • Share via AirDrop, Files, Messages and more • Projects are saved – continue anytime

FREE • The full clean-up, preview and mix workflow • 3 video exports (with a small watermark)

PERFECT SOUND PREMIUM – ONE-TIME PURCHASE • Unlimited video exports without watermark • Audio export: M4A, WAV, MP3

Made for vlogs, interviews, podcasts, voice-overs, lectures, phone and drone recordings, rehearsals – every clip where the picture is fine but the sound is not.
