Stereophonic service apparatus, operation method of the device, and computer readable recording medium

A stereophonic service apparatus including:

• a storage unit for matching and storing head-related transfer function data related to a physical characteristic of a user and sound source environment 3D data related to the sound source environment of the user;
• and
• a control unit which extracts a head-related transfer function data candidate group related to the user from the stored head-related transfer function data based on the stored sound source environment data matching a sound source environment test result provided by the user, and sets one selected data candidate from among the extracted candidate group as individual, user-specific, personalized head related transfer function data.

A method of driving a stereophonic service apparatus including a storage unit and a control unit, which includes a step for matching and storing head-related transfer function head-related transfer function data related to the physical characteristics of a user and sound source environment 3D data related to the sound source environment of the user, and a step in which said control unit extracts a head-related transfer function data candidate group related to the user from the stored head-related transfer function data based on stored sound source environment data matched with sound source environment test result provided by the user and set as individualized head-related transfer function data for each user.

A computer-readable recording medium containing a program for executing a stereophonic service method, said stereophonic service method being specialized in that it is a computer readable recording medium which executes a step that matching head-related transfer function data related to the physical characteristics of the user and sound source environment 3D data related to the sound source environment of the user, and extracts a head-related transfer function data candidate group related to the user from the stored head-related transfer function data based on the stored sound source environment data matching the sounds source environment test result provided by the user, and sets one of data selected from the extracted candidates as individualized head-related transfer function data for each user.
