It uses the same state-of-the-art audio enhancement technology found in many hardware products and automatically configures your PC and soundcard to work with the software. You can customize the sound profiles based on your type of speakers (or headphones) and playback content (music, movie, game, voice) and also adjust surround sound effects, bass, speaker size simulation and several other criteria to tweak the sound to your personal preference. Easy to use, astonishing results!
