ABSTRACT:
This invention teaches a method of mixing sound so that a monophonic common ambience audio channel, derived either from a mix of an entire performance, or from a specially created audio mix, is folded back to an individual performer's earphones together with a foldback of that individual performer's microphone or electronic instrument pickup audio signal. The individual performer's microphone or electronic instrument pickup audio is fed to both of a performer's earphones in polarity, while the ambiance mix is fed, simultaneously with the performer's microphone or electronic instrument pickup mix, to both of a performer's earphones, out of polarity, thereby creating a psycho acoustic pseudo stereo effect so that the performer perceives the monophonic ambiance mix as a wide spacious stereophonic field from behind the performer with no specific ability to place an instrument at a specific place in the field.
