Sound Booster can be used to amplify the volume of audio content on websites. The application is constantly monitoring the gain level of the current audio stream, and if it approaches the maximum or minimum volume levels, it prevents the samples from clipping. It ensures that the sound level of all audio files is raised before it gets to the sound card.

Bear in mind that Chrome has its own restrictions on the full-screen mode that are used when the user has selected any extension. Thus, when you try to go full-screen, it prevents you from leaving the tab of the currently playing audio file.
