Remove background noise from a recording

TutuAudio removes steady background noise with a spectral-gate filter that runs in your browser. Adjust the strength and A/B the before/after. Nothing is uploaded; it is free with no sign-up and no limits. Works best on hum, fans and air conditioning; it helps less with crowd chatter or music under a voice, and it is not an AI model.

Record

MP3, WAV, M4A, AAC, FLAC, OGG, WebM and the audio in MP4 videos

Everything runs in your browser — the file never leaves this device

Drop in a recording, the background noise is removed automatically, and you can switch between before and after to compare.

FAQ

Is it free? Do I need an account?
Free, no account, no usage limits, and no watermark on the export.
Is my recording uploaded to your server?
No. Noise reduction runs in your browser; the file never leaves your device.
The voice sounds muffled after cleaning — why?
The strength is too high. Pull the slider back a step and listen again.
Can it remove restaurant chatter?
Only partly. Chatter overlaps the voice frequencies; the tool is best at steady noise like fans, hum and air conditioning.
