1. A method of simulating a spatial sound environment to a listener over headphones comprising:

  • inputting a series of sound signals having spatial components;

    determining a current orientation of said headphones around said listener;

    determining a mapping function from a series of spatially static virtual speakers placed around the listener to each ear of the listener;

    utilising said current orientation to determine a current panning of said sound signals to said series of virtual speakers so as to produce a panned sound input signal for each of said virtual speakers;

    utilising said mapping function to map said panned sound input signal to each ear of said listener; and

    combining said mapped panned sound input signals to produce a left and right output signal for said headphones.
