Louder is a Chrome addon developed by no9 that allows users to enhance the sound beyond the maximum level on webpages. This addon is particularly useful when the sound on a webpage is too quiet, even when the volume is set to the maximum. It can also help balance the volume of sound when it varies significantly over time.

Louder works on both video and audio elements on pages that allow it. To activate the extension, simply click the left mouse button on its icon. For additional options, you can right-click on the extension's icon to access a menu that can be useful in certain situations.

It is important to note that on some pages, it may not be possible to adjust the volume of the played elements due to how the specific page is designed. Additionally, when clicking on the extension button on some pages, the browser may mute the sound. This is due to the security configuration of the specific page or the server it is hosted on and cannot be detected by the extension.

If you find Louder useful, you have the option to support the author with a donation of any amount. Simply check the menu by right-clicking the extension button.
