Perfect Sound
Fix Video & Audio Noise
Free · Designed for iPad. Not verified for macOS.
Clean up hum, hiss, wind and handling noise in your videos and recordings. See the sound on a spectrogram, treat only the parts you choose, and hear before/after.
Turn noisy footage into clear, usable sound — on your iPhone or iPad, without studio gear.
Perfect Sound repairs the audio in your videos and recordings: remove hum and hiss, reduce wind and handling noise, fix clipping and crackle, then shape the tone and export. Import from Photos or Files (MP4, MOV, M4A, WAV, MP3 and more).
What you can fix
- Hum, hiss, wind, handling noise, coughs, audience noise, applause
- Clipping (de-clip) and crackle (de-crackle)
- Sound that's too dull, too harsh, too quiet, or too reverberant — with a 0-5 strength control
- Wrong or unusable passages, using the built-in two-track editor
How it works
Unlike one-tap tools, Perfect Sound shows you the sound on a spectrogram and lets you decide what to change. Mark a problem, choose a treatment, set its strength, and preview the result before you commit. Treat the whole file, or only the seconds you select.
Two ways to work
1. Guided cleanup — pick the problem, import a file, see the spectrogram, preview before and after, and apply to the whole take or selected sections.
2. Two-track editor — load your take plus a cleaner reference, and splice in corrections with crossfades.
Tools
- Interactive spectrogram with section-by-section editing
- Before/after preview for every treatment
- 10-band EQ, reverb, dry/wet mix, master gain
- Video export with the cleaned audio kept in sync (when the source is video)
- Project library — save and continue later
Premium (one-time purchase)
- Video export without the watermark
- Audio-only export: M4A, WAV, MP3
Made for vlogs, interviews, podcasts, voiceovers, phone recordings, lectures, and rehearsal recordings — any clip where the picture is fine but the sound isn't.
Processing runs on your device.

Perfect Sound — a major update, formerly ConcertPro.
New home screen with four clear starting points: guided cleanup, audio filters, the two-track editor, and your project library.
Audio cleanup (new)
- Import one video or audio file and treat hum, hiss, wind, handling noise, clipping, crackle and more.
- Interactive spectrogram with before/after preview; treat the whole file or only selected sections.
- Mixing stage with a 10-band EQ and reverb, then export video with the cleaned audio in sync.
Still here from 1.0
- Two-track editor: replace a passage with a cleaner take using crossfades.
- Video export; Premium removes the export watermark and adds audio-only formats (M4A, WAV, MP3).
- Processing runs on your device.
