Acoustic signal processing method, recording medium, and acoustic signal processing device

An acoustic signal processing device comprising:

• an obtainer that obtains first position information indicating a position of an object that is a moving object in a virtual space, and second position information indicating a position of a listener in the virtual space;
• a first calculator that calculates a moving speed of the object based on the first position information obtained;
• a second calculator that calculates a distance between the object and the listener based on the first position information obtained and the second position information obtained;
• a generator that generates, based on the moving speed calculated and the distance calculated, an aerodynamic sound signal indicating an aerodynamic sound generated when wind caused by movement of the object reaches an ear of the listener;
• and
• an outputter that outputs the aerodynamic sound signal generated.
