ABSTRACT:
A method and apparatus are described for processing audio signals in a particular manner to achieve an enhancement in the perceived sound when the processed audio signals are projected by audio transducers. A predetermined low frequency band of the audio signals is delayed by a time period which is generally less than the refractory period of the human ear and combined with out-of-phase cross-field portions within a particular amplitude range. A predetermined low frequency boost is applied generally of the order of about 3 db. Several embodiments are described to provide improved recordings or enhanced acoustic projections of conventional stereo recordings.
