Hear the difference

Fan noise in. A clear voice out.

Loud fan noise was added to this podcast clip, then Purevo cleaned it up. Turn on the sound to hear it switch between Original and Cleaned up.

Clip from “Matthew McConaughey | Blocks Podcast w/ Neal Brennan” by Neal Brennan, licensed under CC BY 4.0. Shortened to 15 seconds, with fan noise added, then cleaned up in Purevo. Shown only to demonstrate the app; it isn’t an endorsement.
Purevo's Enhance tab with an interview recording, its waveform, and sliders for background noise, room echo, speech clarity, and volume balance

Clean it up, then compare.

Reduce background noise and room echo, make speech clearer, and bring quiet and loud parts closer together. Fine-tune sharp S sounds, voice tone, low rumble, and loudness. Switch between Original and Cleaned up at the same moment to hear the difference.

The Batch tab cleaning three recordings, with one exported, one at 53 percent, and one waiting

Clean up several recordings at once.

Add several files, and Purevo applies your current settings to each one. Track each file’s progress. Save cleaned copies to a folder you choose or next to each original.

The Audio engines tab describing Purevo Clean for everyday cleanup and Purevo Studio for tougher recordings

Two engines for different recordings.

Purevo Clean handles steady fan noise, hum, and light hiss. Purevo Studio does full-band 48 kHz cleanup for tougher recordings, so it takes a little longer.

Purevo's Appearance settings with six color skins: Purevo Green, Slate, Sky, Turquoise, Bordeaux, and Wisteria

Choose how Purevo looks.

Choose one of six colors, then set Purevo to light or dark mode, or have it follow your Mac. You can change the app icon to match.

Clean up videos too.

Open an MP4, MOV, or M4V video. Purevo exports a copy with cleaned-up sound and leaves the picture exactly as it was.

Compare at the same volume.

Match listening volume so the cleaned-up version doesn’t just sound better because it’s louder.

Pick up where you left off.

Recent keeps each cleaned recording and its settings. When you reopen one, Purevo doesn’t clean it again.

Your originals stay untouched.

Purevo always saves a new file. Your original recording is never changed.

Your recordings stay on your Mac

You don’t need an account or subscription. Purevo cleans your recordings on your Mac and never uploads them. It connects only to check for updates or verify your license after purchase. Read Privacy.
