1. A sound processing device, comprising:
circuitry configured to:
obtain a head related transfer function of a user;
obtain first sound data based on actual measurement of sound in a first space;
acquire a plurality of parameters from the obtained first sound data,
wherein the plurality of parameters is associated with specific characteristics of the sound;
generate first sound information by synthesis of the plurality of parameters and the head related transfer function of the user;
generate second sound information based on the first sound information and characteristics of a terminal device connected to the sound processing device;
acquire second sound data in a second space;
generate third sound data based on the second sound data and the second sound information; and
output the third sound data.
