Screenshot / Code Snippet



Someone found the current *beep* sound annoying and asked for a way to change the sound. Such a feature did not exist, so I created this UserScript which adds a button next to the notification settings button. This button opens a popup which allows you to change the sound that will be played on activity. Four presets are available (including the current one). Currently, only MP3 files are supported.


Following the figure in this licensing question, I decided to release it under the MIT/X11 license.


The current version is


In addition to the requirements for the audio notification, a modern browser with UserScript support is required. The UserScript was tested in:

  • Firefox 5
  • Chromium 12
  • Opera 11.50


Bugs and suggestions can be reported by commenting, or emailing me at


The script is written in JavaScript using jQuery. Stack Exchange Chat works with MP3 files, supported by the Flash Player. Although jPlayer supports HTML5 <audio>, this is disabled by Stack Exchange.

You need to restart your browser after installing – Anwar Aug 5 '12 at 7:09
This appears to no longer work. The presets are broken since is no longer in use, and entering a url to an MP3 doesn't do anything. Everything just gives the default sound. – SevenSidedDie May 6 '15 at 20:30
I did some bug fixing to this and posted it on Github: If you want, I'll transfer the repo to you. @SevenSidedDie test it out if you're still interested. I only tested on the latest Chrome. – muru Mar 15 at 4:34

I did some bug fixing to this and posted it on Github:, and added more sounds. Modifications were only tested on recent versions of Google Chrome, and I don't know the media plugin that SE uses well enough to know if I broke anything.
