Abstract:
1. A sound system, comprising: a left speaker and a right speaker located in close proximity; a left channel audio signal; a right channel audio signal; and a sound processor receiving as inputs said left channel audio signal and said right channel audio signal, said sound processor configured to cross-cancel a spectrally weighted stereo difference signal with said left channel audio signal and said right channel audio signal prior to applying said left channel audio signal and said right channel audio signal to said left speaker and said right speaker, respectively; wherein said sound processor further comprises a phase equalizer for equalizing the phase of said spectrally weighted stereo difference signal prior to cross-cancellation, and a plurality of phase compensators, having a phase characteristic complementary to said phase equalizer and said spectral weighting filter over a frequency band of desired cross-cancellation, placed in series along each of said left channel audio signal and right channel audio signal, respectively, prior to cross-cancellation.
