1. An audio processing system for generating compensated audio signals suitable for reproduction through a loudspeaker system, comprising:

  • source means for providing two channels of audio signals having head-related transfer functions imposed thereon;

    compensation means for providing cross-talk cancellation of the audio signals and for providing naturalization compensation of the audio signals to correct for propagation path distortion including filtering means for substantially modifying frequency and phase response of the cross-talk cancellation and naturalization compensation at frequencies beginning at a frequency above 600 hertz and beginning at least at a frequency below ten kilohertz in such a way as to release the cross-talk cancellation at such high frequencies thereby generating compensated audio signals.
