Abstract: Provided are a computer system for producing audio content for realizing a user-customized being-there and a method thereof. The computer system may be configured to generate audio files based on respective audio signals that are respectively generated from a plurality of objects at a venue, set spatial features at the venue for the objects, respectively, using a production tool, and generate metadata for the audio files based on the spatial features. An electronic device may realize a being-there at the venue by rendering the audio files based on the spatial features in the metadata. That is, a user of the electronic device may feel a user-customized being-there as if the user directly listens to audio signals generated from corresponding objects at a venue in which the objects are provided.

Abstract: Provided are a computer system for transmitting audio content to realize a user-customized being-there and a method thereof. The computer system may be configured to detect audio files that are generated for a plurality of objects at a venue, respectively, and metadata including spatial features that are set for the objects at the venue, respectively, and to transmit the audio files and the metadata for a user. An electronic device of the user may realize a being-there at the venue by rendering the audio files based on the spatial features in the metadata. That is, the user may feel a user-customized being-there as if the user directly listens to audio signals generated from corresponding objects at a venue in which the objects are provided.
