摘要:
An information processing apparatus includes a data acquisition unit to acquire pieces of acoustic data based on sound collection performed by sound collection units at different positions, a setting unit configured to set a virtual sound source position corresponding to a piece of acquired acoustic data for each acquired piece, based on a sound collection position and correlation information indicating a correlation between the piece of acoustic data and another piece of acoustic data, the virtual sound source position set so an imbalance between virtual sound source positions respectively corresponding to the pieces of acoustic data is smaller than an imbalance between sound collection positions, and a generation unit configured to generate audio playback data for reproducing a sound for a virtual listening position, by processing piece(s) of acquired acoustic data based on the virtual listening position and the virtual sound source positions set by the setting unit.
