Recording in Stereo, Binaural and Spatial Audio

Stereo audio recording is the simultaneous capture of sounds with two microphones. The stereo illusion is produced by a minor difference in sound between the left and right channels. When two separate microphones are put in various places, the recorded sound has the appearance of distance and width because the recorded signals have varied arrival times and levels. Some of the most expensive microphones for Binaural Recording include the 3Dio FS, Neumann KU 100, and others, which range in price from £400 to £7000.

Binaural audio tracks are quite costly, which is a disadvantage. The concept of spatial audio arose as a result of the early discovery of binaural audio/recordings. Another disadvantage is the inability to vary the dynamics of the audio stream since the microphones are situated in identical places on both sides. Spatial audio is obtained by employing numerous approaches that cause the sound to travel in different directions. When these approaches are combined, the term HRTF is used (Head-Related Transfer Function). When recording spatial audio, the location of the microphone is taken into account from the listener's point of view (High Fidelity, 2021).
