Abstract: The present technique relates to an information processing apparatus, an information processing terminal, an information processing method, and a program which enable a sound content in accordance with an action by a participant in a conversation to be output in an immersive state. An information processing apparatus according to an aspect of the present technique includes: a storage unit configured to store HRTF data corresponding to a plurality of positions based on a listening position; and a sound image localization processing unit configured to provide, by performing sound image localization processing using the HRTF data selected in accordance with an action by a specific participant among participants of a conversation having participated via a network, a sound content selected in accordance with the action so that a sound image is localized at a prescribed position. The present technology can be applied to a computer which conducts a remote conference.

Abstract: The present technique relates to a reproducing device, a reproducing method, an information processing device, an information processing method, and a program, by which realistic contents can be provided while reducing a load of processing. A reproducing device according to a first aspect of the present technique includes a reproducing unit configured to reproduce object audio contents including a first object reproduced by using a personalized HRTF that is an HRTF personalized for a listener, and a second object reproduced by using a common HRTF that is an HRTF shared among a plurality of listeners. The present technique is applicable to a device that reproduces contents including audio data.
