Here is a 4K video with binaural microphones in the ears of two performers.
Fr (Front) is the sound which was heard at the eras of performer in front showing his back. Rr (Rear) is the sound which was heard at the ears of performer in rear showing his face. Originally Rr sound is reversed as R/L so corrected L/R is available.
