ABSTRACT:
A stereophonic sound reproduction system comprises a first signal converter receptive of an audio signal for converting it into a binaural signal containing information as to the localization of the original sound source at a desired location in a listening area, and a second signal converter for converting the binaural signal into a signal containing no acoustic components which would produce the effect of crosstalk between listener's ears when the signal is reproduced in the listening area. A sound field expansion system is also disclosed which includes a converter which processes an input signal for generating an acoustic signal which localizes virtual sound sources so that the listener is given the impression of an expanded listening area.
