    摘要: Disclosed is an object based audio contents generating/playing apparatus. The object based audio contents generating/playing apparatus may include an object audio signal obtaining unit to obtain a plurality of object audio signals by recording a plurality of sound source signals, a recording space information obtaining unit to obtain recording space information with respect to a recording space of the plurality of sound source signals, a sound source location information obtaining unit to obtain sound location information of the plurality of sound source signals, and an encoding unit to generate object based audio contents by encoding at least one of the plurality of object audio signals, the recording space information, and the sound source location information, thereby enabling the object based audio contents to be played using at least one of a WFS scheme and a multi-channel surround scheme regardless of a reproducing environment of the audience.
