ABSTRACT:
An audio-imaging system includes at least first and second input channels for receiving first and second channel audio input signals and at least first, second and third output signals which are produced as a combination of the first and second channel audio input signals and a nonzero parameter. The parameter is common to the first, second and third output signals and may be made adjustable in order to vary the width of the audio image produced in order to compensate for composition mixing of a program source applied to the input channels. A sound-image analyzer is also provided which processes a program source applied to the input channels to at least three fully separated levels representing left, right and center directions of the program source in order to determine a value of the parameter.
