摘要： A bitstream reconstruction method and apparatus are provided. The method includes constructing an initial bitstream by rendering sound source information and geometry information within a reference radius from an initial location of a user accessing a virtual space into spatial audio, collecting location information according to a movement of the user within the virtual space, and reconstructing, based on a relationship between the reference radius and a movement radius identified according to the collected location information, the initial bitstream constructed by corresponding to the initial location of the user.
