Does it simulate surround sound like Dolby ATMOS?

Dolby Digital 5.1 is six-channel surround sound, intended for speakers around the listener, all roughly at ear level: front left, front center, front right, behind left, behind right, and low-frequency effects.
Dolby Atmos adds a height component to the listening experience, by utilizing sound from above, either directed downwards, or beamed upwards and reflected from the ceiling. The sound format doesn’t have discreet channels for each speaker, but the Atmos audio equipment decodes the 3D position (direction) of “sound objects” to speakers based on your personal setup.
