Binaural audio

Definition

Binaural audio is a recording technique that uses two microphones to create a 3D stereo sound sensation for the listener, mimicking how human ears perceive sound in real life. This technique enhances the immersive experience of audio storytelling by placing the listener in the midst of the action, making it feel as if they are actually present in the environment. By capturing sound from two distinct points, binaural recordings create spatial awareness and depth, which can significantly enhance narrative engagement.
