How to enhance audio online
Most recordings that sound “bad” aren't actually distorted or badly performed. They're just sitting on top of a layer of constant background noise: room hum, a computer fan, air conditioning, street rumble. That noise floor is what makes a recording feel muddy, tiring to listen to, and unprofessional. Lift it out, and the same recording suddenly sounds close, clear and intentional. That's why CleanNoise treats noise removal as the core of audio enhancement rather than a separate step. Here's how to use it:
- Add your recording. Drag an MP3, WAV, M4A or video file into the tool at the top of this page.
- Let CleanNoise enhance it. The AI detects the background noise automatically and separates it from your voice, so you don't need to select a silent section by hand.
- Optional: restore clarity. For muffled, echoey or low-quality recordings, switch on “Remove echo / reverb” for an extra restoration pass, then keep whichever sounds best.
- Preview free, then download. Compare the original and the enhanced 30-second preview, then download your clean WAV for $0.99.
Your file is uploaded only to produce the enhanced result and is deleted within 24 hours. The 30-second preview is free with no sign-up. For loudness normalization, EQ presets, and longer or batch files, see CleanNoise Pro.
Why noise removal is the biggest lever for perceived quality
Listeners judge audio quality mostly by how much effort it takes to follow, and background noise is the single biggest source of that effort. A slightly imperfect microphone or an unpolished take is easy to forgive; a persistent hiss or hum underneath every word is not. That's why removing noise first, before reaching for EQ or loudness tools, produces the biggest jump in how “enhanced” a recording sounds, and it's exactly what this tool is built to do well.
Using it as an audio restoration tool
“Audio restoration” usually means one of two very different problems. The common one is a recording that's perfectly intact but buried, under tape hiss, a noisy room, mains hum or the hollow echo of a bare space. That's the case CleanNoise is built for: it lifts the noise and reverb off an old or rough recording so the voice or music underneath comes back clear, which is what most people are really after when they search for audio restoration software or an audio repair tool. The other kind, physical damage to the waveform itself (clicks, crackle, dropouts, digital clipping), needs dedicated spectral-repair software; this tool doesn't declick or de-clip. If your recording is fundamentally there but sounds noisy, hissy or echoey, drop it in above and hear the restored version free before you pay.
