Over the past few years, 3D audio has evolved greatly to complement many other technologies. At this point in time, not only can we enjoy 360-degree video, but also listen to three-dimensional sound that captures audio exactly as we’d hear it in real life. And with more and more industries finding new applications for 3D audio, consumers are fast ditching their HD audio and surround sounds to race for new devices that support this technology.

3D audio works by adding a layer of depth to recorded sounds, instead of sweeping sound between the left and right ears like your average stereo track. This creates the illusion that sound appears to be coming from not just all around you, but also from both close to you and far away on every side, giving you the ability to enjoy a much more immersive audio experience. 3D sounds have many interesting properties and are used to further many industrial purposes. Here are four of the top applications for this technology.

Music

3D audio technology is changing the way we enjoy our music. Instead of settling for a realistic simulated performance of a live orchestra, you can now transport yourself right to the stage and listen to music as it’s heard in the very midst of the performers. The technology is also very popular in the music production industry, particularly among affluent producers such as “Waves”, who are beginning to incorporate spatialisation for music playback with NX software.

Entertainment

There’s no better way to completely submerge yourself into the depths of your favourite films than with 3D sounds. And though film theatres will likely always prefer their surround sound systems over 3D audio, you can always make your home binging sessions more exciting with this technology at your fingertips.

Virtual reality

Virtual reality and 3D audio go hand in hand – one just wouldn’t be enjoyable without the other. Virtual reality strives to gives its users a perfectly realistic visual experience, one that includes all the right sounds matching up with the right sights. This is done by the VR headset, which calculates the movements of your head and ensures that the 3D audio image stays in place while you move about.

Military

3D audio and spatialisation are used by the military to help pilots differentiate between multiple audio messages that they may receive at the same time. Spatialisation allows pilots to program different audio messages to come from different places around them, so the sounds overlap less with each other, making each individual message clear and understandable.
