ABSTRACT:
The manipulation system and apparatus receives electronic signals which are to be processed and recorded for playback as enhanced stereophonic audio signals from two laterally spaced loudspeakers in front of the listener. The system and apparatus processes those signals to produce a conditioning signal, such as which would be produced by virtual room boundaries, which is heard together with the original signals so that an enlarged listening area is perceived by the listener. By amplitude and phase control of the signal to the two real speakers, the system and apparatus provide a means for control over the enhanced sound field. This enhanced sound field is perceived by the listener as being contained within boundaries larger than those normally reproduced by stereophonic speakers.
The system and apparatus generates a conditioning signal for the enhancement of natural, and generation of artificial, spatial qualities present in stereo signals usually masked in the acoustic environment in which reproduction takes place, through generation of phantom boundaries. The apparatus monitors its own output and shuts down if the output contains qualities that cannot be cut onto a record. The apparatus provides self-adjustment in the electronic system to maintain spatial masking reversal at a constant value regardless of program material.
