1. An information processing apparatus for rendering one or more audio objects comprising:
a user position unit determining information for a position of a user and transmitting the user position information;
an acquisition unit coupled to the user position unit that acquires low accuracy position information for at least one of the audio objects having a first accuracy and indicating a position of the at least one audio object within a space relative to the user position information and acquires additional information for obtaining position information for the at least one audio object relative to the user position information that has a second accuracy higher than the first accuracy;
a position information calculation unit coupled to the acquisition unit that obtains the position information of the at least one audio object relative to the user position information on a basis of the low accuracy position information and the additional information; and
a renderer coupled to the position information calculation unit receiving data relating to the at least one audio object including the position information, generating reproduction audio data for the at least one audio object localized to the position information of the at least one audio object, and outputting the generated reproduction audio data to a speaker.
