An information processing method includes: obtaining a stream including (i) first position and orientation information indicating a position and an orientation of a sound source and (ii) a sound signal indicating a sound that the sound source outputs; obtaining second position and orientation information indicating a position and an orientation of a head of a user; and setting a spatial resolution for three-dimensional audio processing to be performed on the sound signal, according to a positional relationship between the head of the user and the sound source and using the first position and orientation information and the second position and orientation information.
