When binaural recordings are listened to using headphones, the result is a genuine three-dimensional sound that provides the listener the feeling of being in the place where the audio was captured as well as facing the same direction as the microphone was during the recording. Binaural recording is the practise of capturing sound with a stereo binaural microphone designed to resemble two human ears. A binaural microphone is a form of stereo microphone that features two prosthetic, human-shaped ears with microphone capsules implanted into each ear canal. Binaural microphones capture sound in the same way as your natural ears do. HRTF (Head Related Transfer Function) and our ear shape generate a very distinct character for each and every produced sound. Binaural refers to having two ears, and the shape of the animal and human ears differ. Our brains recognise these changes as navigational cues. Locating the source of the sound is mainly possible because of binaural hearing. The microphone's ear-shaped pinna shapes incoming sound waves in the same manner as your ears would shape incoming sound waves (3Dio, 2019).
