toMono is a free Chrome extension developed by Mihai Pop that aims to enhance the audio experience while watching YouTube videos. As many users may have encountered, some videos on YouTube only have audio on one channel, resulting in a mono sound. This extension addresses this issue by faking stereo sound through doubling the mono channel.

With toMono, users can easily toggle between mono and fake stereo by clicking the extension button. Upon the first click, the audio is transformed into fake stereo, providing a more immersive audio experience. On the second click, the extension restores the maximum number of channels per device destination to its initial value.

toMono is a simple yet effective tool for those who prefer a stereo audio experience while watching YouTube videos. It is a valuable add-on for Chrome users who want to enhance their audio experience without any hassle.

Please note that toMono is an open-source project available on GitHub, where users can access the source code and contribute to its development.
