We know 3D and 360 audio, but 8D audio?
To understand how it works. First, we have to explain what is binaural.
Binaural is a recording technique to capture stereo audio that is simulate the sound waves exactly as your ears hear. The picture below explained what that means.
In the picture is the microphone popularly used to create binaural recording. The ear shape cover redirect the sound wave before it reaches the microphone inside. It works exactly like our ears. This creepy looking head below was used for the Beck's concert on 2013 to capture the sound for their 360 cameras.
Now you are ready for the ASMR.
The name stand for Autonomous sensory meridian response (ASMR). By looking at this picture below you probably already know what it is and how it works. The performer record sound use binaural microphone to simulate the intimate activities with your ears.
You can understand more by checking famous YouTuber Rapunzel ASMR video:
However, for some people this idea maybe not so new. In fact many band experiment this idea back on 80s, and published their binaural songs.

So what is 8D audio?
Recent years things has changed thanks to digital audio workstations. The remix getting more and more popular. Many music producers and sound engineers started to remix and produce immersive 360 audio for the headphones. However, instead of record and mix the binaural sound into the music. The new approach is to use binaural simulation software to manipulate the original stereo recording. By panning the sound in 360 degree to create binaural effect like the singer is singing from different directions to your ears. For this reason we think it is fair to define the "D" from 8D as "direction".

You can see many ASMR and 8D music stated headphones only. This means you can not listen to the effect with speakers, even home theater speakers. But due to OPSIS II's special acoustic spatial processor that allow you to enjoy 8D/9D/16D music. Use two OPSIS II to playback the front and rear surround will get you the same experience you heard from your headphones.
