The main difference between surround sound and 3D sound is that surround sound creates an omnidirectional sound on one sound plane, whereas 3D sound creates a spherical sound experience in which the individual voices, instruments and sounds can be assigned according to direction. To achieve this, the 5.1 and 7.1 speaker systems are supplemented by ceiling speakers. This technology no longer works exclusively channel-based, but with audio objects that are processed in real time in a digitalsignal processing, changed in level, frequency behavior and runtime, assigned to the different speakers. In total, DTS:X supports 32 speaker positions.
DTS:X is said to be characterized by sound fullness, brilliance, clarity and dynamics. It is used in cinemas and, in the future, also in home theaters and is used in Ultra HD Blu-Ray and in AV receivers.
