Bring your music, movies and games to life through the genius of 4D sound quality.
Imagine being surrounded by every note, noise and nuance of your favorite album, movie and game. That's exactly what the AstoundSound Expander 3.0 does—it takes the sound coming from just two speakers and turns it into a spherical, 4D listening experience that's so real, it's just like being there.
AstoundSound™ uses 4D sound technology software built on over a decade of research and development into how the human brain perceives sound. In a similar way to what Hi-definition did for visual experiences, 4D audio immerses listeners in a 360-degree, realistic sound experience that addresses azimuth, elevation, distance and movement over time. In other words, a 4D listening experience creates the sense of movement in a 3D listening environment.
