8-Dimensional Sound: What 8D Music Is and How It's Made

A knock on the door, and different songs in each ear at once.

Online, you can occasionally come across 3D and 4D audio, but today, there are also recordings labeled '8D.' The DeTalks team looked into whether it's really possible to give songs a sense of volume, and what feelings this effect creates.

What 8-Dimensional Audio Actually Is

In reality, sound doesn't have dimensions at all. 8D music, just like 3D and 4D, is processed stereo audio that creates the sensation of sound coming from different directions.

The 8D effect makes you feel like you're in a larger space, but you have to listen to this kind of music with headphones, or the effect is lost. Sounds shift from one speaker to the other, but both ears perceive them at the same time. When the brain can't separate the audio into distinct sources, this is also called the crossover effect.

This way, if a 130 Hz tone, for instance, is played into the right ear, and a 120 Hz tone into the left, the 10 Hz difference between them creates a phantom third sound, adding the illusion of depth to what's heard.

8D music can sound as if a voice is 'moving' around the listener, heard alternately in the right and left headphone. This can be created using muffled sounds and their processing — the tones themselves create the effect of distance and volume.

You can also hear two different instruments playing separately at the same time — with binaural audio, it's possible to listen to one track in the right headphone and another in the left. There's also a way to process a sound, like a knock at a door, for instance, and enhance it by adding a 360-degree effect. This kind of processing is called ambisonic audio, and the sound seems to come from every direction.

To achieve the 8D effect, technologies like equalization, panning, and adding desired effects are used. Equalization changes the audio's frequencies, which is what makes the brain create the phantom sound mentioned above. Panning technology, meanwhile, distributes sound across different audio channels to create the illusion of movement in what's heard.

Songs can be converted to 8D format even using phone apps. But to create a track like this yourself, you'd need to record each instrument separately and mix them individually for each ear.
