    Abstract: The present disclosure relates to an information processing apparatus and an information processing method which are capable of improving an efficiency of acquiring a predetermined type of audio data among a plurality of types of audio data. Audio data of a predetermined track is acquired in a file in which a plurality of types of audio data are divided into a plurality of tracks depending on the types and the tracks are arranged. The present disclosure is applicable to, for example, an information processing system including a file generation device that generates a file, a Web server that records a file generated by the file generation device, and a video playback terminal that plays back a file.

    Abstract: The present technology relates to an audio signal output device and a method, an encoding device and a method, a decoding device and a method, and a program for realizing audio reproduction with a more realistic feeling.In a case where an audio signal generated to be output as a sound from an ideal speaker that is a virtual speaker placed in an ideal position is input, the distance between the ideal speaker and a real reproduction speaker is determined. Gain adjustment is then performed on the audio signal with the gain corresponding to the determined distance, the audio signal subjected to the gain adjustment is reproduced by the reproduction speaker. Accordingly, even in a case where there is a difference in position between the ideal speaker and the reproduction speaker, audio reproduction with a more realistic feeling can be realized. The present technology can be applied to reproduction devices.

    Abstract: The present technology relates to an encoding device and method, a decoding device and method, and a program which can obtain high quality audio with a less code amount.A signal encoding unit encodes audio signals and outputs a resultant signal code string. A coefficient encoding unit encodes mixing coefficients for use in a mixing process of the audio signals and outputs a resultant coefficient code string. A multiplexing unit multiplexes the signal code string and the coefficient code string and outputs a resultant output code string. The coefficient encoding unit rearranges the mixing coefficients at the time of encoding the mixing coefficients on the basis of distances between input-side sound source positions and speaker positions on a reproduction side and calculates differential values between the mixing coefficients on the basis of arrangement order of the-mixing coefficients, thereby encoding the mixing coefficients. The present technology is applicable to the encoding device and the decoding device.
