How to remove background noise from audio for free
Background noise, whether it's the constant hum of an air conditioner, a computer fan, street rumble or room hiss, sits behind your voice in a narrow, steady band of frequencies. CleanNoise runs an AI model that separates that steady noise layer from the changing frequencies of speech, so the voice stays natural while the noise drops away. Here's the whole process:
- Add your recording. Drag an MP3, WAV, M4A or video file into the tool at the top of this page.
- Let CleanNoise clean it. The AI detects the background noise automatically, so you don't need to select a silent section by hand.
- Optional: remove echo. If the recording is echoey, muffled or low-quality, switch on “Remove echo / reverb” for extra restoration, then compare both and keep whichever sounds best.
- Preview free, then download. Hear a 30-second preview at full quality, and download the complete file when you're happy with it.
Your file is uploaded only to produce the cleaned result and is deleted within 24 hours. The preview is free with no sign-up; the full-length download is $0.99 per file, or included in CleanNoise Pro.
