Method and apparatus for processing audio signal

摘要

An audio signal processing apparatus including an index estimation unit that receives three-dimensional image information as an input and generates index information for applying a three-dimensional effect to an audio object in at least one direction of right, left, up, down, front, and back directions, based on the three-dimensional image information; and a rendering unit for applying a three-dimensional effect to the audio object in at least one direction of right, left, up, down, front, and back directions, based on the index information.

主权项

1. An audio signal processing apparatus comprising:
a memory device; a processor which performs operations, the operations comprising:
receiving three-dimensional image information and an audio signal, and generating index information for applying a three-dimensional effect to the at least one audio object of the audio signal in at least one direction from among right, left, up, down, front, and back directions, based on the three-dimensional image information; andapplying the three-dimensional effect to the at least one audio object in the at least one direction from among right, left, up, down, front, and back directions, based on the index information, wherein the three-dimensional image information comprises at least one from among a minimum disparity value, a maximum disparity value, and location information of an image object having at least one from among the maximum disparity value and the minimum disparity value, for each respective image frame.
