How 3D Audio Works

- The emergence of beamforming in speaker technology allows multichannel audio to be delivered without multiple speakers or headphones. This short animation explains how we hear surround sound and how playback through speakers and headphones fails to match the unique advantages of beamforming.

Fun fact binaural audio has been around since the early 1900's aka 3d sound it's not new just uncommon until now
Thats funny. The crossfeed from stereo speakers ( especially reference monitors) produces a more accurate image than with headphones. You want that crossfeed. If you hear something thats more left in a game the right speaker is usually quieter and still late to your left ear, giving you a better sense of left and right panning in the image. Binaural only works better if its programmed correctly, which in most games it is not.
I feel like this vid is about to have hella views
Yup
didnt happen
Same
@@SV-zi9os Unfortunate, but it is relevant now so it may happen.
Nah, didnt happen
Use three timers separate axis of space and mathematics delay and frequency can manipulate air and light each point in the any geometric room the best method is the projection of 3 circle for each axis in space time and musics signals enscrypt the timing of the moving 3 circle and where they meet is the sound and predetermined geometry of sound
And also sound waves split in to two so we're got the twin waves only works on stereo devices.
Heard about this “8D Audio Music” that stuff is amazing. Is this what that is?
most likely, 8D is just using the higher number 8 is just used to entice you
3D audio si better tbh
@@mad3byj Yea lmao, "8D". People will fall for anything.
@@silent_anon404 Yeah, man, some people are dumb, including me
its just alot of effect automation here a helpful video on it ruclips.net/video/VWX4I0oyk18/видео.html
On reality we listen only one channels each left and right but in 3D we create sound space dimensions.
It's doesn't work for me because I only have 1 ear
It could still work with binural audio because they use the shape of an ear to record audio. I would think that should work
Just get a second ear
Then I guess you can only hear sounds at a 180 degree angle.
@@fionn9229 LOL
@@fionn9229 fair enough
sounds like a Jedi mind trick. How about they make 3D TVs first since they stopped it for some time now.
Thanks
Wow, tat's some terrible misinformation. Crosstalk isn't what you're describing. Crosstalk is when part of the signal that's supposed to play only on one channel also plays on the other channel and has nothing to do with how/what reaches or ears. It is an electronic phenomenon that happens inside the audio equipment. The way speakers deliver sound to the ear is exactly how it is delivered when an actual sound originates from any position between the two speakers shown. Also, our ears cannot precisely determine where a sound is coming from on the vertical axis, in fact our ears are particularly bad at that.
My suggestion is that you go back and research your information regarding crosstalk being only an electrical phenomenon. The explanation of left or right exclusive information "crossing" over to the other ear is real. Crosstalk cancellation is a common process in speaker-based binaural sound reproduction.
Solid suggestion, greatly misplaced though.
Of course, the phenomenon of information „crossing over to the other ear“ is real. However:
1. This phenomenon is NOT called crosstalk. In proffesional audio language, the word „crosstalk“ has a very specific and narrow meaning. We all understood what meaning they wanted to convey by using this word, and it has become erroneously use in this context, but this being (supposedly) intended as a somewhat educational video, such errors do it a disservice. But it is a minor issue, opposed to...
2. Regardless of what word they use, the example is poor, because what they've shown doesn't represent what they're referring to, as you put it, sound leaking over to the other ear. The animation shows a stereo speaker setup and sound coming from both speakers to both ears simultaneously, with each speaker's sound reaching both ears, not just the one closest to it. But this is how real sounds in real world work. Imagine sound only coming from one of the speakers with the other speaker being completely silent. Sound from that speaker will reach both ears. Is this not identical to what the animation at 0:18 represents? How we detect naturally occuring sounds? The animation showing both speakers emitting sound at the same time does not represent this „crosstalk“ they're referring to, it just shows how we phisically detect sounds from two different directions at the same time.
3. There is no exclusive information when talking about stereo speaker setups. Media intended to be reproduced through a stereo speaker setup does not contain „single-ear-exclusive“ information because the equipment is not designed to do so. Recordings are made intentionaly and with the expectation to be used with a speaker setup and to take advantage of sounds from each speaker reaching both ears, because this most closely resembles naturally occuring sounds (in that specific field of space between the two speakers, as mentioned). Binaural recordings are made specifically for headphone use and in a way that takes advantage of each speaker more or less perfectly isolated from one another. Of course efforts for „crosstalk cancellation“ exist, but they exist only to make recordings that aren't intended for speaker playback at least somewhat usable with a speaker setup.
This video does not suggest this, however. It never tries to explicitly state that content, which isn't made for speaker playback, suffers when played back through speakers and is reproduced better when played back through the equipment it was made for (which is kind of obvious, isn't it?). Instead, it implies that ALL material is better reproduced through headphnes with their 3D audio technology, regardless of how and why a recording was made, and does so through misleading statements as described in 2.
@@slinch In the research facility at USCD, where the the patented version of beamforming was invented by the director of the music technology and a couple of grad students, they refer to crosstalk cancellation. It IS called crosstalk and using phase to control it is an on going area of research.
Just here to see how my ps5 mic works
The PS5 will win
Oh definitely
duh
should you colab with me?
Which is better then? 3d or 8d?
12d
3d
I checked bc of the fortnite update
???
«3d» audio is a gimic for cheap headsets... like gaming socks or gaming gloves:p i have even seem headsetts promote dolby atmos... that proves my point😂🙈 stupidasshitmarketing
It'd be good to put space in ur last statement imo lol
Anyone else think this shit sounds so bad?
