The distribution of spatial audio has begun with Apple Music.Apple is described as a spatial audio, but Sony has been developing a similar playing environment for several years under a 360 Reality Audio brand.The same is true for Amazon to be distributed to Echo Studio as a 3D audio.
Some of these distribution formats use Dolby ATMOS and those that use MPEG-H, but both have the same purpose and basic concept (when both are compatible with both (Amazon).There is).
This time, I would like to talk about how to enjoy it and the recommended playback environment while introducing the songs used for evaluation in the spatial audio of Apple Music.
How much does the sound turn to the "true circle"?
There are several environments to regenerate spatial audio in Apple Music, and it has already been introduced in this magazine, so I will not dig deeper here.However, it is better to enter from either "enjoy with Dolby ATMOS -compatible surround system" or "enjoy with headphones".
I am 7 for home theater.1.2 configuration (7).Since a system of two top speakers is added to one surround system, a spatial audio will be enjoyed by connecting Apple TV or Mac to the AV receiver.
Ideally, 7.2.4 or more (4 top speakers) will be in the sound field, but in the sense of a three -dimensional effect, it is very different from listening with headphones.In the music stage, you can feel the feeling of taking a shower of sound.
However, it is not realistic to build a large system for spatial audio.For this reason, both Sony and Apple can enjoy three -dimensional sounds with headphones and earphones (Apple are also built -in speakers).However, depending on the equipment used, the three -dimensional effect varies.
"What, after all, you have to be Apple's earphones?"
You may think, but you can enjoy the "atmosphere" with any equipment.The difference is the degree of three -dimensional effect.If you have an Apple or Beats compatible product, if you don't have it, set the Dolby Atmos to "Always on" in Music settings and try to play the next song.

The theater system was able to confirm the sense of the sound effect beautifully and close to the round, and some sound effects could be heard from the upward upward direction.
This is a single benchmark (standard), the movement of the sound, the three -dimensional effect of the sound field, the shape of the overall sound field (the ideal semicircular spheres), and the processing of virtual three -dimensional sound is performed.I decided to test some earphones and headphones while paying attention to whether the range of range balance, such as thinning the band, will not occur.
Best tuning is AirPods Max
あらかじめ予想されていたことではあるが、Best tuning is AirPods Max。色々な楽曲を試すほどに、AirPods Maxと空間オーディオの相性の良さを感じた。
In order to make the three -dimensional sound field in two earpieces require a fairly detailed phase management, we anticipated that the company would automatically recognize the company's products and make optimal processing, but here.It's no wonder that some people choose AirPods Max for spatial audio if they are well built up.
In the example of TOUR DE France (Etape 2), the sound effect does not turn around in a true circle, but the front and rear depth and height direction are very good, and the sound effects are slightly horizontally elliptical.The feeling of turning.Furthermore, it is easy to grasp the position in the height direction.
例えばTiest & Sevennの「BOOM」はアトラクティブな音源の移動なども面白いが、地を這うように湧き出るベースの音が楽しめる。

AirPods Max has a function to correct the sound of the sound depending on how it is attached, especially the way of hearing the bass, and is constantly performed to bring the feedback to the expected sound.It may be contributing to enhance the reproducibility of spatial audio and the texture of bass.
AIRPODS MAX was a headphone with a fairly good sound quality as a wireless headphone, but it seems that its original territory was demonstrated by spatial audio regeneration.
Of course, the optimization seems to be optimized for AirPods Pro, AirPods, Powerbeats Pro, etc. Rather than using "always on" to use other companies' earphones, the "elliptical shape that turns the sound effect" is size before and after.However, the height direction is less likely to appear compared to AirPods Max.Of course, the low -frequency reproduction band is narrow only on the earphones, so the texture and volume of the bass also differ greatly.
Nevertheless, it seems that the adjustment of each model is properly adjusted in the part that "virtually realizes three -dimensional sound".
What is the feeling of other companies earphones/headphones?
As I wrote at the beginning, it is possible to enjoy the atmosphere of a three -dimensional music expression that is different from stereo mix, even if Dolby Atmos is turned on "always on" and using other companies' earphones and headphones.
However, the front and rear depth and height cannot be as expected as Apple genuine.Some of the products may be in good condition, but it happens to be close to the default conditions of the expected three -dimensional sound processing assumed by Apple.
In this test, I tried using Sony "WF-1000XM3" and noble audio "Falcon Pro" as wireless earphones, and "Fitear Titanium" as wired earphones.As a result, WF-1000XM3 has some back and rear depths, but Falcon Pro and Fitear Titanium have a considerable narrower depth before and after.
This is not the low quality of each earphone.It's simply a matter of compatibility.Apart from the size and shape of the sound field, if it is evaluated by the quality of the sound, Fitear Titanium is a low -frequency playback ability of the truly low -frequency playback, and the bandwidth balance is very good.
I don't use many headphones, but I tried it on the open-type SRH-1840, the sealed Sony "MDR-Z7", and the wireless Sony "WH-1000XM3".After all, the three -dimensional effect of the sound field is not as made by Apple.I don't think there is no possibility that optimization for spatial audio will be possible in the future, but for the time being, Apple will optimize only for its own products.
Again, it can be enjoyed with earphones/headphones made by other companies, but the difference is clear when you experience how to hear it in AirPods Max.You will surely want AirPods Max.
Many songs that give you a natural immersion
For the test, I chose a song with an easy -to -understand production, but the use of three -dimensional sound technology varies greatly depending on the intention of the production side, such as artists and engineers in charge of mixing.It is similar to trying to use the stereo regeneration technique in various ways.
"Sideways", which features Valerie Broussard and Nurko by US DJ Illenium, starts like a normal stereo song, but as the rust approaches, many emotional sounds are stacked, wrapping the listeners with loud lumps.

How do you feel when you listen to NORA JONES's debut song "Don't Know Why?"
あなたのプライバシー設定では、このコンテンツをご利用できません。こちらで設定を変更してくださいSome virtual surround for headphones can be heard from the previous person to resolve the localization in the brain, but this song has a semicircular shape with a natural stereo mix.It may not be surprising, but if you listen to it well, it will be a place that makes you feel like you are following the band as a singer? (Of course, how to hear the sound on the stage.It's actually different.)
A small live house feels like a jazz session is being developed in front of you, and the air is tight in a tight space.Wayne Shorter's "JUJU" can enjoy such an atmosphere.

By the way, as mentioned earlier, Apple Music spatial audio has the best tuning for Apple devices, but you can enjoy some earphones at hand.Music is fun and Nambo.
First of all, it would be fun to enjoy it with the earphones at hand and find an interesting arrangement like a treasure hunt.At present, there is not a lot of compatible songs yet, but there are still a wide variety of good content so that you can forget the time just to enjoy a fresh experience.
In the meantime, the new works will gradually be arranged in spatial audio, and the songs created by the artist themselves for spatial audio will come out.
At that time, it's not too late to think again, "Which device is the most fun to listen to?"
