1. A method, executing on hardware, for processing sound signals for a surround left channel (SL) and a surround right channel (SR), comprising the steps of:

  • generating a continually varying delay between the signals of the surround right channel (SR) and the surround left channel (SL), wherein the continually varying delay decorrelates the surround left channel (SL) and the surround right channel (SR), and wherein the continually varying delay varies over time so as not to have a fixed value;

    processing the signals of the surround left channel (SL), wherein processing of the signals of the surround left channel (SL) includes the step of introducing a first delay to the signals of the surround left channel (SL); and

    processing the signals of the surround right channel (SR), wherein processing of the signals of the surround right channel (SR) includes the step of introducing a second delay to the signals of the surround right channel (SR),wherein the first delay and the second delay provide the continually varying delay between the signals of the surround right channel (SR) and the surround left channel (SL).
