A sound signal processing device performs sound field control by controlling each virtual sound source position of a primary sound source and an ambient sound source that are separated sound signals obtained from an input sound source, in accordance with changes in the velocity and the traveling direction of an automobile. The sound signal processing device includes: a velocity information acquisition unit that acquires velocity information about a mobile apparatus; a steering information acquisition unit that acquires steering information about the mobile apparatus; and a sound control unit that controls output sounds from speakers disposed at a plurality of different positions in the mobile apparatus. The sound control unit performs sound field control by controlling the respective virtual sound source positions of the primary sound source and the ambient sound source that are separated sound signals obtained from the input sound source, in accordance with the velocity information acquired by the velocity information acquisition unit and the steering information acquired by the steering information acquisition unit.
