MonoBass is a free Chrome extension developed by no9 that allows you to monofy the bass frequencies in the currently playing video. With just a click on the extension button, MonoBass combines the left speaker's content below 3kHz with the right speaker's, and vice versa, resulting in a rich and powerful mono bass sound.

This extension is particularly useful when you want to enhance the low-frequency content of the videos or audios you are currently watching or listening to. It works seamlessly on both video and audio elements on webpages that support this feature.

To activate MonoBass, simply click the left mouse button on its icon. However, in some cases, clicking on the extension button may mute the sound due to the security configuration of the specific page or server it is hosted on. Additionally, on certain pages, it may not be possible to affect the audio of the played elements, depending on how the page is designed.

For a complete sound reset, it is recommended to reload the page. If you find MonoBass useful, you have the option to support the author by making a donation of any amount. Simply right-click the extension button to access the menu and find the donation option.
