Remove Noise
Reduce background noise in video or audio, then preview and download the result.
Remove Noise cleans the audio track of a video or an audio file. Upload, pick a strength, pick a format, export.
Set Noise reduction to Light, Medium, or Strong. Medium is the default.
Noise reduction
Remove Noise uses a non-AI FFT denoiser at a fixed noise floor of -40 dB. The three settings change the amount of reduction. It does not separate speakers or guarantee removal of all background sound.
| Setting | Reduction |
|---|---|
| Light | 6 dB |
| Medium | 12 dB |
| Strong | 20 dB |
Start at Light on a recording that is nearly clean. Strong removes more, but it takes more of the voice with it.
Listen to the source before you export and to the result after it, then download. Use Replace file to try another recording after processing finishes.
Output formats
From a video you get MP4, MP3, or WAV. From an audio file you get MP3 or WAV.
MP4 keeps the first video stream and the cleaned first audio track, and re-encodes to H.264 with AAC audio at 128 kbps. MP3 is 192 kbps. WAV is uncompressed 16-bit PCM.
Only the first audio track survives
It processes the first audio stream and discards the rest. A file with separate language or channel tracks comes back with one.
