Reproduction apparatus, reproduction method, information processing apparatus, information processing method, and program

A reproduction method comprising the steps of:

• acquiring content including audio data of each of audio objects and rendering parameters of the audio data for each of a plurality of presumed listening positions;
• and
• rendering the audio data on a basis of the rendering parameters for a selected predetermined presumed listening position, and outputting an audio signal.

A program that causes a computer to execute processing including the steps of:

• acquiring content including audio data of each of audio objects and rendering parameters of the audio data for each of a plurality of presumed listening positions;
• and
• rendering the audio data on a basis of the rendering parameters for a selected predetermined presumed listening position, and outputting an audio signal.

An information processing apparatus comprising:

• a parameter generation unit that generates rendering parameters of audio data of each of audio objects for each of a plurality of presumed listening positions;
• and
• a content generation unit that generates content including the audio data of each of the audio objects and the rendering parameters generated.
