Hi, this is Wayne again with a topic “Virtual Surround Sound as Fast As Possible”.
Virtual Surround is a true representation of human ingenuity and the advances that scientific research can have on technology. It essentially tricks your ears into thinking that sound, which is coming from a 2.1 channel set up or a small strip of speakers using a technique called digital. Sound projection is actually coming from a 5.1 channel or higher speaker setup. If anyone doesn’t know what the naming scheme for a surround speaker setup means.
The first number 5 in this case refers to the number of speakers in the system and the number after the point in this case 1 refers to the number of subwoofers in the system. Both 2.1 and digital sound projection worked because of advancements in psycho acoustics, which is a study of sound perception. They trick your ears by carefully directing sound waves at specific angles and bouncing them off walls to make you think that the sound is actually coming from behind or beside you rather than in front of you.
You see your ears are pretty adept at recognizing where sound is coming from. This is why, when you hear something drop in a silent room, you’re often able to instantly identify whether the sound is to your left or right, we can tell what direction a sound is coming from, because we have two ears which have a certain distance between them. So, for example, a sound to your left will be louder in your left ear than in your right ear. Also, the sound waves will hit your left ear a fraction of a second sooner than your right.
It’S these slight differences in timing and volume that tell you what direction a sound is coming from on the x-axis. This is called the interaural level difference and interaural time difference. Lucky for developers of virtual surround sound systems, the x-axis is the only one they have to worry about. This is because of something that many refer to as the cone of confusion, which is an area in which objects which are above or below us, caused the same interaural level, difference and interaural time difference.
This also applies to objects which are in front of us or behind us at certain angles. So how do virtual surround systems know how to simulate a 5.1 or higher channel system? Quite simply through recording a system of that size with directional microphones in a real world? Setting which takes into account the interruptions of a sound wave by your head neck and shoulders and simulating that with an algorithm. This is why some systems will have a room size rating and why some even need to be configured with a microphone to work properly. The size of the room needs to be accounted for, so the waves can properly bounce off the walls to simulate full surround experience virtual surround headphones, do something similar by using the shape of your ears to project sound from different angles.
Many of these have a general one-size-fits-all setting based on average ear sizes, but options like Razer surround are quite customizable, so you can tweak the placement of each virtual speaker to perfect your listening experience if you so choose, to give an example of what good virtual surround Should sound like through headphones check out this video, which uses bio-neural sound, recording to simulate, surround sound, so that’s it virtual surround in itself. Isn’T that complicated, but it’s made possible by a variety of extremely complicated scientific studies and tests, but the execution is actually quite simple.
