Video Noise Remover for Mac

Noise Remover is a free macOS drag-and-drop app that reduces background noise in a video’s audio. The picture is copied as-is. Drop one or more videos on the app and it writes a new file next to each original, named NAME_clean.ext.

Description

Requirements

• A Mac running macOS (Apple Silicon or Intel)
• ffmpeg, installed with Homebrew: brew install ffmpeg

The app looks for ffmpeg at /opt/homebrew/bin/ffmpeg, or anywhere in your PATH.

How to use it

1. Download the zip and unzip it. Keep the whole Noise Remover folder together — the app, clean-one.sh and voice-model.rnnn must stay in the same folder. You can move that entire folder into Applications.
2. The app is not signed. The first time you open it, right-click the icon and choose Open, then confirm. macOS may block a regular double-click.
3. Drag one or more video files onto the Noise Remover icon. You can also open the app and pick the files.
4. When it finishes, the cleaned copy is saved next to the original, with _clean in the name. The original is not overwritten.

.mov files are saved with uncompressed 24-bit PCM audio. Other formats are saved with AAC audio at 256 kbps. The video stream is not re-encoded.

FAQ

Does this remove the background behind a person in the video?

No. It reduces background noise in the soundtrack (hiss, rumble, room noise). The video image is left untouched.

Why does macOS say the app can’t be opened?

The app is unsigned. Right-click it, choose Open, and confirm once. After that it should open normally.

The app doesn’t start, or nothing happens when I drop a video.

Install ffmpeg with brew install ffmpeg, and make sure clean-one.sh and voice-model.rnnn are still in the same folder as the app.

Does it work on Intel Macs as well as Apple Silicon?

Yes, as long as ffmpeg is installed (Homebrew works on either chip).

Is there a Windows version?

No. This download is for macOS only.
