Abstract
A stereophonic binaural recording and reproduction method for audio signals presented to headsets. Signals of the left stereo channel are supplied to the left ear, weighted with the outer ear transmission function of the left ear for the angle range of between 0.degree. to 45.degree. to the left of the median plane, and to the right ear, weighted with the outer ear transmission function of the right ear for the same angle range. Additionally, time-delayed signals of the left stereo channel are supplied to the right ear, weighted with the outer ear transmission function of this ear for the opposite angle range, wherein the delay is markedly outside of the time range of the sum localization and of the audible echo. The signals of the right stereo channel are supplied to the right and left ear in the same manner but mirror-inverted relative to the median plane. Any necessary equalizations of the amplitude-frequency characteristic are carried out without influencing the time structures by means of linear phase digital filters on the outer ear transmission functions.
