How it works

  1. 01

    Choose a file for Noise Gate. It accepts MP4, MOV, WEBM, MKV, MP3, WAV, FLAC, OGG, M4A. Most files stay in this tab.

  2. 02

    Set the options on the workbench — preview, crop or timeline when this tool has one — then press Run.

  3. 03

    Download the result. It is also saved in your tray so the next tool can pick it up without another upload.

About this tool

An 80 Hz high-pass removes rumble, then 10 ms windows below the threshold are pulled down. Breath and room tone get quieter; the voice stays. For neural denoise of a fan behind a talker, use Noise Reduce (RNNoise).

Questions

What can I open in Noise Gate?
Noise Gate accepts MP4, MOV, WEBM, MKV, MP3, WAV, FLAC, OGG, M4A. Older video containers such as AVI, WMV, FLV, MPEG and 3GP are decoded by the server encoder.
Does Noise Gate upload my file?
Most MP4, WebM, images and PDF stay in this tab. Instagram/TikTok crops, DVD, GIF, iPhone presets, stabilize, hard containers (AVI, WMV, HEVC) and a failed local encode go to the server encoder. The file is processed and discarded — we do not keep a copy.
How large can the file be?
Free: 500 MB and 8 exports a day. Plus (waitlist) raises the daily cap. A pasted public file URL is also accepted.
