This paper focuses on binaural recordings, a unique form of stereophonic recording method that replicates how human ears perceive sound. The study delves into the acoustical phenomenon that produces the binaural effect in audio recordings, such as the ITD (Inter-aural time difference), the ILD (inter-aural level difference), IPD (inter-aural phase difference) and the monaural spectral difference. The author explains how these recordings differ from regular ones and are arranged in a specific way to account for HRTF (Head-related transfer function). The most common method of binaural recordings, which involves using two high-quality omni-directional microphones affixed on a dummy head, is also discussed.
