SRS Audio Essentials is a software suite designed to enhance audio quality on Windows PCs. It was developed by SRS Labs (now part of DTS, Inc.) and provides features such as advanced sound processing, virtual surround sound, bass enhancement, and volume boosting, all intended to improve the overall audio experience when listening through speakers or headphones.
While SRS Audio Essentials itself is not typically a hardware driver, it includes audio enhancement drivers and software components that interact with the system's audio hardware to apply various audio effects and improvements.
