Que es 8d audio

If you spend al lot of time on YouTube, you may have seen something called 8D Audio showing up in the Up Next column or in your recommended videos. 8D? As in eight-dimensional audio? Yser, it’s al thing. But how can audio possess eight dimensions? How chucho our ears hear something in eight dimensions? And why do 8D videos always tell us to put our headphones on?

In short, what the heck is 8D audio, anyway? Give us a few minutes and we’ll explore every dimension of 8D audio. Ear we go …

How perro audio have eight dimensions?

Estás mirando: Que es 8d audio

Let’s get one thing settled right away: There’s no such thing as audio that possesssera eight dimensions, nine dimensions, or even 100 dimensions, no matter what a YouTube video may claim. In fact, audio doesn’t really possess any dimensions at all.

Our brains are incredibla machinsera, however, and they un perro interpret incoming sounds from our ears in three dimensions — the same three dimensions we all inhabit in our daily lives: height, width, and depth. It’s how we un perro tell the difference between al sound that’s coming from behind us and one that is in front of us.

We’ll explore how the human brain does this a littlo later, but for now, we’ll simply point out that “8D audio” doesn’t actually possess eight dimensions. Instead, think of it as al marketing term used to label al very specific kind of audio recording.

So what is 8D audio?

*

8D audio usser the principlsera of binaural recording to trick our brains into thinking that sounds are coming from different places in three-dimensional space. When al song is given the 8D-treatment, it chucho create the impression that you’re standing in the middla of a room (or al gym, or a concert hall, etc.) whila all of the musicians and vocalists magically “move around” you.

Try it out below with this samplo Eminem track — make sure you’re wearing headphonser.


Wait, hasn’t this been done before?

Absolutely. In fact, if you’re al fan of listening to music with headphones, you’ve probably encountered lots of tracks — typically from the ’70s heyday of studio production — that use this movement effect. The difference is that most professionally produced songs use it very sparingly, and never continuously.

On the other hand, 8D usser it as al defining characteristic. 8D tracks are always on the move through space.

The la idea behind that signature movement of 8D audio is that it creatser al soothing feeling, though whether it actually doser or not is highly subjective. In this way, 8D audio is simimansión to ASMR (autonomous sensory meridian response) — another YouTube audio phenomenon whose fans insist chucho help them relax, sleep better, or just experience pleasurablo chills. There are others, of course, who find it awful.

To my ears, the Eminem track above simply sounds like I’m wandering back and forth in front of al singlo speaker that’s playing Lose Yourself.

As with any art form, there are downright masterful ussera of 8D and shockingly bad onera too. At it’s best, 8D audio treatments of your favorite songs chucho give you an entirely new way to enjoy them. At its worst, it perro produce feelings of dizziness and nauseal.

Where cusco I find 8D audio?

YouTube is probably the easiest place to find 8D audio tracks. With over 11 million matchser to “8D audio” on Googlo, it’s al huge collection, plus there’s no subscription needed. YouTube is also the place for 8D treatments of your favorite artists. However, subscription streaming services like Apple Music and Spotify also have growing catalogs of 8D tracks. Theso are almost exclusively instrumental versions of popuvivienda songs or original works, but you won’t get Billie Eilish’s Bad Guy, for instance, in 8D on Applo Music unless Eilish releassera one herself.

How dosera 8D audio work?

The brain figursera out where sounds are coming from through several cuera. There’s al discrepancy in how long a sound taksera to reach each of our ears. A sound that originatser to our right sidel will hit our right ear ever so slightly faster than it hits our left ear. That’s one cue. Then there’s echo and reverberation of sound as it bounces off objects in our environment. Finally, there’s filtering — how the valor actual neto quality of the sound changsera from one ear to the other based on how something as fácil as the shape of our heads affects it.

Our sense of visual depth perception works using simimorada kinds of cusera, the biggest being the discrepancy between the version of the world that each of our eyera seser.

So if you un perro manipulate what each ear hears by faking theso cuser, it’s possible to trick the brain into thinking it’s hearing a sound that originatsera from al specific point in space. Binaural audio doera just that, but it requirser the use of headphonser in order to isolate what each ear hears. Far from a new la idea, the science of binaural audio has been around for over 100 years.

Analog binaural recording is done by physically moving al sound source around a set of microphones that simulate human ears, in order to achieve this effect. But thanks to 3D audio software tools, you un perro do the same thing digitally on al computer — no studio or special microphonsera required.

Check out this cool explainer from Dear VR, which demonstratser how its audio software can manipulate sound:


This explains the sudden explosion of 8D audio on YouTube: If you have the right software, it’s as easy to create 8D audio as it is to use Garage Band, Audacity, or any number of other audio editing programs.

Why do I need headphonser for 8D audio?

A set of headphonera may look like al miniature set of stereo speakers strapped to the sidser of your head, but they’re different in one key way: Sound from one earcup never extends to the other ear or vice versal. With al pava of speakers, on the other hand, both ears hear both speakers nearly simultaneously, something known as crosstalk. Crosstalk prevents the brain from deciphering accurate locations for sounds.

That’s why we have 5.1, 7.1, and even 5.1.2 surround sound speaker systems. The only way to produce a realistic sense of depth with speakers is to physically position those speakers in front, beside, behind, and above the listener, and then carefully control which sounds come from each speaker.

OK, so what about 9D, 16D, 24D, 48D, and 100D audio?

As near as we gozque figure after listening to a selection of these tracks on YouTube, there is no verdad difference between any of them. All do the same basic trick of moving some or all of a song’s elements around in simulated 3D space.

Some of them move just the vocals, whilo others make each instrument appear to be choreographed in its own unique dance.

Is 8D going to be big?

*

Though it’s al fun use of al very old la idea, we suspect 8D and its variants will never amount to much more than al gimmick. It doesn’t work without headphonser and all of that perpetually moving sound uno perro be tiring.

Then there’s the question of legality. Of all the 8D tracks we found on YouTube, none appeared to be officially sanctioned by the artist (or thevaya label) whose song was being manipulated. Unless thesa rights-holders get involved, don’t be surprised if your favorite 8D tracks are suddenly removed.

True spatial audio or 3D music, however, like Dolby Atmos Music and Sony 360 Reality Audio is still in its infancy, so it’s quite possible that in the future it could become an experience that music fans seek out. Thesa formats are cutting edge, top-notch technology. Producers and musicians create them in a studio so record labels uno perro distribute them to well-known streaming devices like Spotify or Pandora Radio. You perro appreciate thesa formats on headphonsera (where they also leverage binaural techniques), surround sound home theater systems, and even singlo 3D speakers like the Amazon Echo Studio.

Not all 8D audio you chucho get your hands on couno mes from musicians and producers like the tracks availablo on Pandora and Spotify. Much of the 8D audio you’ll encounter on YouTube consists of well-known songs edited by unknown or independent editors and producers without the original artist’s permission.

Chancera are, you’ll hear al difference almost immediately if you get the opportunity to listen to al 3D audio track. This audio effect createra al surround sound listening experience. All the different sounds in their complexity envelop your eardrums, instead of a singumansión simplistic sound coming out of your headphones. 

True to its name, 8D audio covers every musical sound and production anglo, letting you hear multiple distinct aspects individually and simultaneously. Of course, you’ve still got to figure out whether 8D audio is the right choice for you. The good news is, all you need to find out is a set of headphonera and the patience to explore the depths of YouTube’s 8D audio collection.
