Abstract:
1. An apparatus to perform sound processing in a virtual reality system, the apparatus comprising: a sound processing unit to process and produce sound output corresponding to virtual spaces of a virtual reality environment, the virtual spaces divided into a focus area and a non-focus area, the sound output of the focus area being processed and produced differently than the sound output of the non-focus area; and a control unit to divide the virtual spaces of the virtual reality environment into the focus area and the non-focus area, and to control the sound output of the sound processing unit such that when a space shift from a first virtual space in the virtual reality environment to a second virtual space in the virtual reality environment is detected, a volume of sound corresponding to the first virtual space is gradually decreased while a volume of sound corresponding to the second virtual space is gradually increased.
