A practical binaural recording system

A practical. binaural recording unit was designed and manufactured t o extend the present day high quality sound recording-reproducing equipment development So as t o u t i l i z e some of the benefits inherent in a stereophonic system. A review of theoretical factors involved in binaural sound recording and reproduction is presented, with a description of t h e t e c h n i c a l equipment developed t o provide a high quality binaural system consistent with reasonable 0;verd.l equipment cost. Some novel problems and effects encountered i n the development program, as well as experiences with binaural recording techinques i n t h e f i e l d s of radio transmission, court room recording, and test instrtmentation, are described.
