Download nomus

Free, no account. Pick where you listen: one tab, your whole computer, or your phone. Every app runs the same engine and the same model.

Apps: version 0.11.3, released 28 October 2026 (Android 0.9.5). Chrome extension: version 0.5.0 ("Clean my mic" in Chrome) is not yet in the Chrome Web Store, coming soon; the desktop app covers Zoom, FaceTime, Teams and other apps meanwhile (the store still offers the previous version). What changed

One line installs nomus on macOS and Linux

Paste it in Terminal. It finds your system, checks the download and installs the app.

curl -fsSL https://agrohi.com/nomus/install | sh

Read the script first: curl -fsSL https://agrohi.com/nomus/install | less, or open the raw file.

What it does on a Mac

Downloads nomus 0.11.3 and checks its sha256 and its Apple code signature.
Copies nomus into Applications and opens it. No password.
Nothing passes through a browser, so macOS shows no "Not Opened" warning.

The microphone driver comes later: nomus installs it the first time you turn on Microphone, with one password prompt. macOS 14.2 or newer, Apple silicon or Intel.

Upgrade and remove

nomus updates itself. Running the same line again also upgrades it.

To remove nomus (it asks before removing the microphone driver):

curl -fsSL https://agrohi.com/nomus/install | sh -s -- uninstall

What it does on Linux

Picks the .deb for your PC (amd64 or arm64), downloads nomus 0.11.3 and checks its sha256.
Installs it with sudo apt-get install, which asks for your password for that step only.

For Debian-family systems with PipeWire 0.3.49 or newer: Ubuntu 24.04, Debian 12, Linux Mint 22. The microphone needs no driver on Linux.

Upgrade and remove

Run the same line again to upgrade. nomus also checks for updates when it starts.

To remove nomus (it runs sudo apt-get remove nomus):

curl -fsSL https://agrohi.com/nomus/install | sh -s -- uninstall

If macOS says "nomus" Not Opened

This build is signed but not notarized by Apple, so macOS blocks the first launch of a copy downloaded in a browser. Drag nomus to Applications, then paste this line in Terminal:

xattr -dr com.apple.quarantine /Applications/nomus.app && open /Applications/nomus.app

Updates after that install themselves. The one-line installer above avoids this step.

Requirements

macOS 14.2 or newer (it uses the Core Audio process tap added in 14.2)
Apple silicon or Intel (one download for both)
On first start, allow nomus to record system audio (Privacy & Security, Screen & System Audio Recording)
Microphone cleaner (beta): one driver install, which the app does for you, and the Microphone permission; set it up. An experimental switch makes nomus Microphone the default input for apps without a microphone menu (if your input ever stays on nomus Microphone, pick your mic in System Settings > Sound > Input)
Checks for updates at launch; turn it off under About, Check for updates

Requirements

A one-time setup so nomus can mute the originals: one command from a computer, or wireless debugging on Android 11+. Setup guide
Filters apps that allow audio capture. Most video, podcast and social apps do; YouTube is tested. Some music and film services block capture, among them Spotify, SoundCloud, Netflix, Disney+ and Prime Video. They play normally, unfiltered, and nomus tells you which ones they are. Which apps work
Network access only for the one-time setup, which talks to your phone itself. Audio never leaves the phone

Check a download

Every file has a sha256 checksum, listed above and in SHA256SUMS. The one-line installer checks it for you. To check a file by hand, compare it with the one you downloaded:

shasum -a 256 nomus_*.dmg          # macOS
sha256sum -c SHA256SUMS --ignore-missing   # Linux, in the download folder

The macOS and Linux files download from dl.agrohi.com, Agrohi's download address on Cloudflare R2 (the files are larger than this site's host serves). Same operator and domain; the checksums here and the app's update signature are unchanged.

Every app ships the same model. Its sha256 is 9d97a25bbd1d33d60af9bdf035c973f383b88156a48e346174451a49e8c3264f.

Windows and iPhone

Windows: use the Chrome extension. A Windows app is not planned: Windows lets an app copy what other apps play but not silence the original, so a whole-system filter would need a signed kernel audio driver.

iPhone and iPad: not possible. iOS does not let an app process the audio of other apps.
