Classification: CPC H | IPC H

Claim 4:
5. A decoder of an obstacle effect processing system, the decoder comprising:
an obstacle plane search unit configured to receive a parameter for an obstacle candidate plane extracted from spatial information, and determine, in response to the parameter, whether the obstacle candidate plane is an obstacle related to a path between a position of a virtual sound source and a position of a user; and
an obstacle effect processor configured to apply a sound effect according to the obstacle to an audio signal when the obstacle candidate plane is the obstacle,
wherein the obstacle candidate plane is a plane of an object that may become the obstacle in a sound propagation path between the virtual sound source and the user, and
wherein the obstacle candidate plane is represented by reducing information of the object, and
wherein the parameter includes at least one of a unique number of the obstacle candidate plane, coordinates representing a position and a shape of the obstacle candidate plane, or transmission information of the object.
