Find noisy Chrome tabs and quickly switch to, mute, or close them. Who made that sound? is a Chrome extension that helps you quickly find the tab currently playing audio. Chrome shows a speaker icon on tabs that are making sound. When you only have a few tabs open, that is usually enough to find the source pretty easily. The problem starts when you have a lot of tabs. For people like me who often work with dozens of Chrome tabs open, even finding one tiny speaker icon can become surprisingly annoying. It gets worse when tabs are spread across multiple windows, when you are using an external monitor, or when you have several similar pages open at the same time. You can clearly hear something playing somewhere, but you end up scanning tab bars one by one just to find which window and which tab it is coming from. I also often ran into this situation when using a MacBook connected to an external monitor. After closing the laptop, even if I had paused the audio, it would sometimes suddenly start playing again. I made this extension for exactly those moments. Click the “Who made that sound?” icon in the toolbar, and it shows only the tabs that are currently making sound. You can instantly see which tab is playing audio, jump to that tab, and, if needed, mute or close it right from the popup. Stop hunting for where the sound is coming from. Find it and turn it off right away.
