Recording and play-back two-channel system for providing a holophonic reproduction of sounds

摘要: A two-channel sound recording and play-back system for providing a holophonic reproduction or of sounds is herein disclosed. The comprises cables electronic apparatus stereophonic type recording, where plurality microphones are arranged in an adjoining mutualy angled relationship so as to provide, during the operation, effect due phase differences at each frequency intensity difference least middle-high acoustic frequencies. comprises, addition source amplifying system, diffusers corners parallelogram, listening point being preferably center said front rear receiving recorded signal without modifications, whereas, respectively, receive pressure which adjusted, by perspective corrector, from -15dB +9dB, modified response thereof with delayed emission, broaden range up 360°, thereby play-back.
