Dolby Digital Plus™: Surround Sound Anywhere, Everywhere
Dolby Digital Plus™ creates a realistic game-play environment that lets you hear every window smash, feel every explosion, and experience every wipeout as if they're really happening. Surround Virtualizer creates a virtualized surround sound experience of stereo or multichannel content over built-in speakers or over headphones. Whether you're playing games, watching Blu-ray movies, or streaming videos, your P55 is an awesome multi-entertainment hub when it has advanced Dolby Digital Plus™.
