Reproducing device, reproducing method, information processing device, information processing method, and program

An information processing device comprising:

• a content acquisition unit configured to acquire object audio contents including sound source data on a plurality of objects and metadata including a flag indicating whether the object is to be reproduced as a first object reproduced by using a personalized HRTF that is an HRTF personalized for a listener or a second object reproduced by using a common HRTF that is an HRTF shared among a plurality of listeners;
• an audio processing unit configured to perform processing using the common HRTF on audio data on the object selected to be reproduced as the second object on a basis of the flag;
• and
• a transmission data generation unit configured to generate transmission data on the contents including channel-base data generated by the processing using the common HRTF and audio data on the first object.

An information processing method that causes an information processing device to:

• acquire object audio contents including sound source data on a plurality of objects and metadata including a flag indicating whether the object is to be reproduced as a first object reproduced by using a personalized HRTF that is an HRTF personalized for a listener or a second object reproduced by using a common HRTF that is an HRTF shared among a plurality of listeners;
• perform processing using the common HRTF on audio data on the object selected to be reproduced as the second object on a basis of the flag;
• and
• generate transmission data on the contents including channel-base data generated by the processing using the common HRTF and audio data on the first object.

A program that causes a computer to perform processing of

• acquiring object audio contents including sound source data on a plurality of objects and metadata including a flag indicating whether the object is to be reproduced as a first object reproduced by using a personalized HRTF that is an HRTF personalized for a listener or a second object reproduced by using a common HRTF that is an HRTF shared among a plurality of listeners;
• performing processing using the common HRTF on audio data on the object selected to be reproduced as the second object on a basis of the flag;
• and
• generating transmission data on the contents including channel-base data generated by the processing using the common HRTF and audio data on the first object.
