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.

The macOS, Linux and Android apps (version 0.9.0) are in testing and not released yet. The Chrome extension (version 0.4.0) is available now. Changelog

Chrome extension

Filters any tab you choose. Works on Windows, Mac, Linux and ChromeOS.

Add to Chrome

Requirements

  • Chrome 116 or newer, or another Chromium browser
  • Installs and updates through the Chrome Web Store

macOS

Filters everything your Mac plays: browsers, Spotify, video calls, games.

Coming soon

Requirements

  • macOS 14.2 or newer (it uses the Core Audio process tap added in 14.2)
  • On first start, allow nomus to record system audio (Privacy & Security, Screen & System Audio Recording)
  • Checks for updates at launch; turn it off under About, Check for updates

Linux

Filters everything your PC plays, through a PipeWire output called nomus.

Coming soon

Requirements

  • A Debian-family system with PipeWire 0.3.49 or newer: Ubuntu 24.04, Debian 12, Linux Mint 22, Pop!_OS 24.04. Only a .deb is offered.
  • Ubuntu 22.04 and Linux Mint 21 use PulseAudio by default and are not supported; nomus says so when it starts there.
  • Install: sudo apt install ./nomus_*.deb
  • Checks for updates at launch; turn it off under About, Check for updates

Android

Filters what other apps play on your phone.

Coming soon

Requirements

  • Android 10 or newer
  • 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
  • No internet permission: the app cannot use the network

Check a download

Every file has a sha256 checksum, listed above. Compare it with the file you downloaded:

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

Every app ships the same model. Its sha256 is d649b6b26f70df1a94cddbe0e8190e2ae72475b97b05dcebfe5df81285d4162d.

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.
