Assignee: SONY GROUP CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 11:
12. A non-transitory computer-readable storage medium storing instructions that, when executed by at least one processing circuit of a sound processing apparatus, causes the at least one processing circuit to perform a method comprising:
acquiring an audio object signal and metadata of the audio object signal, wherein the metadata is position data of an audio object associated with the audio object signal;
determining, based on the position data, a plurality of sound outputting units, wherein the plurality of sound outputting units form a polygon surrounding a sound image localization position;
determining, from the selected sound outputting units, a plurality of combinations of sound outputting units, wherein each combination contains at least two sound outputting units;
determining output gain coefficients for the plurality of sound outputting units at least in part by calculating gain coefficients for the plurality of sound outputting units based on a positional relationship between the plurality of sound outputting units with respect to each combination of the plurality of combinations of sound outputting units, wherein:
calculating the gain coefficients comprises calculating the gain coefficients for the plurality of sound outputting units based on a positional relationship among the plurality of sound outputting units and the sound image localization position; and

outputting the output gain coefficients for the plurality of sound outputting units.
