Abstract:

A system and method are disclosed for providing a two channel signal to the ears of a listener through an audio system. The audio system includes a plurality of audio signals which are played through a plurality of loudspeakers. A plurality of propagation paths exist from the loudspeakers to the ears of the listener. Crosstalk is canceled in the audio system by providing the two channel signal which is to be received at the ears of the listener as an input to a crosstalk compensating network. The crosstalk compensating network is operative to provide an inverse crosstalk signal which cancels the crosstalk caused by the propagation of the audio signals from the plurality of loudspeakers along the plurality of propagation paths to the ears of the listener. The two channel signal is equalized via an equalization transfer function whose magnitude is substantially proportional to a first function applied to the frequency crossfade between a second function of a monophonic compatible equalization transfer function and the second function of a binaurally transparent equalization function. A plurality of audio signals are generated which are suitable for playback through the plurality of audio speakers and propagation to the ears of the listener.
