Binaural audio is audio captured in real time based on how we hear the world to our own ears. Binaural microphones capture the exact location of any sound source around the microphone, given its relationship to the person doing the capturing.
What is binaural audio? Binaural audio is a new way to hear sounds around you. A 2-channel system is a pair of speakers or headphones. Binaural audio is not stereo made up of two multi-directional microphones where one mic is placed with precision, inside the ear. Binaural sound is intended to create a 3D audio sensation for the listener actually being at the location of the recording.
The process begins by using a “dummy head recording” where a mannequin has two microphones, one in each ear. The word “binaural” is not a synonym for “stereo.” Normal stereo recordings do not take into account natural ear spacing or “head shadow” of the head and ears, which happens to be a function of the way a person is listening.
With binaural audio, the listener generates their own “interaural time differences” (ITDs), and ILDs (interaural level differences). The microphone used in binaural audio resembles the shape of a human head, complete with the ears that have two microphones built into the dummy’s ear canals. A binaural recording is exactly what the listener hears during a performance given that the microphones capture what is audible.
