With the emergence and improvement of VR technology, this century-old audio recording technique has suddenly become very relevant. How do these binaural audio recordings work and why are they suddenly so exciting to talk about?
The technology behind is quite simple. In short, a binaural recording uses microphones shaped like human ears. The ear-shaped microphones reshape the audio waves the same way our human ears do. This way, when the audio is played back in a stereo headset, the brain understands how the audio waves have been reshaped, which gives the listener a hyper-realistic feeling of knowing exactly what direction each sound is coming from. Binaural audio recordings are incredibly immersive because the ability to place every single sound in space makes us feel as though we are standing in the very place the audio was recorded.
The basic principles of this technology have remained unaltered since its inception in the 1880s. But since the recent efforts of 3D and VR to bring immersive experiences to users, binaural audio is more relevant than ever. As an example, developers of VR games can now use omni-binaural microphones to record binaural audio from every conceivable angle. Wherever you turn your head, your whole field of view along with the complete spatial directionality of every sound follows your gaze – a revolutionary development, that gives us a glimpse into what very well could be the future of audiovisual media.
