Binaural audio is a recording technique that uses two microphones to create a 3D sound experience. This method mimics how human ears perceive sound, capturing the nuances of direction and distance. When listened to through headphones, binaural audio can make you feel as if you are in the middle of the action, whether it's a concert, nature sounds, or a movie scene. This immersive experience is often used in virtual reality and gaming to enhance realism. By placing sounds in a three-dimensional space, binaural audio helps users feel more connected to the environment, making it a popular choice for creators like filmmakers and game developers.
