1. A sound externalization system, comprising:

  • a localizer configured to collect information related to a first location of a user in an environment and a second location of an acoustically reflective surface in the environment;

    a controller configured to;

    determine a third location of a virtual sound source in the environment;

    generate a first left head related transfer function (HRTF) and a first right HRTF that simulate characteristics of sound radiated from the virtual sound source directly to the user;

    determine a reflected sound path from the virtual sound source to the user that includes reflection of sound by the acoustically reflective surface;

    generate a second left HRTF and a second right HRTF that simulates characteristics of sound from the reflective surfaces to the user, wherein the second left HRTF and second right HRTF are different from the first left HRTF and first right HRTF; and

    generate a sound signal corresponding to the virtual sound source.
