nomus works in Google Chrome 116 or newer, and in other Chromium browsers, on Mac, Windows and Linux.

Start filtering

1. Open a tab that plays sound: a video, a podcast, a lecture.
2. Press ⌘ Shift Y (Ctrl Shift Y on Windows and Linux), or click the nomus icon and choose Filter this tab.
3. The icon shows ON. Press the shortcut again, or click Stop, to hear the original.

Common problems

Filter this tab is greyed out

Chrome does not let extensions capture its own pages, such as chrome:// pages, the Chrome Web Store and the new tab page. Open an ordinary website and try again.

The sound plays but nothing changes

Open the nomus popup and check that Mode is nomus-v1, not Bypass, and that Strength is up. If the status line shows an error, click Stop, then Filter this tab again. If that does not help, turn nomus off and on in chrome://extensions.

Some music still comes through

nomus works best when voices lead. When the music is much louder than the speaker, or an instrument sounds very like a voice (a solo violin, a synth lead), part of it passes. Singing is kept on purpose.

The sound is slightly behind the picture

nomus adds 20 milliseconds, too little to see on a speaker's lips. Wireless headphones add their own delay on top. Wired headphones or speakers remove that part.

Only one tab is filtered

nomus filters one tab at a time. Starting it on a second tab moves it there.

Does it work on my phone?

Not yet. nomus runs in Chrome on a computer.
