The headline feature is the ability to boost system volume beyond the 100% hardware limit. With version 1110514, you can increase output up to 500% of the original maximum.

The Two Modes of Amplification
One of the most interesting technical aspects of this software, preserved in version 1.11.0.514, is its ability to use two different methods to boost sound, preventing distortion:
- APO Injection: This method works at the system level. It’s lightweight and works for almost all applications, making it the default choice for general use.
- Code Injection: For applications that resist APO (like some protected media players or browsers), Sound Booster can inject its processing code directly into the application. This ensures that nothing escapes the volume boost.
