How it works

  1. 01

    Choose a file for Noise Reduce. It accepts MP3, WAV, FLAC, OGG, M4A, AAC, OPUS, AMR, MP2, WMA, AIFF, AIF, AC3, EAC3. 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

Audio is resampled to 48 kHz, processed in 10 ms frames by RNNoise (Apache-2.0 WebAssembly), then mixed with the original so you can keep some room. It is trained for speech. A fan behind a talker is the intended case; a music stem or a second voice will not be carved out cleanly.

Questions

What can I open in Noise Reduce?
Noise Reduce accepts MP3, WAV, FLAC, OGG, M4A, AAC, OPUS, AMR, MP2, WMA, AIFF, AIF, AC3, EAC3. Older video containers such as AVI, WMV, FLV, MPEG and 3GP are decoded by the server encoder.
Does Noise Reduce 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.
