■ Play Auro-3D in the finest environment. How far can you approach the sense of raw? Immersive audio such as Dolby Atmos and 360 Reality Audio (sometimes called spatial audio, stereos, 3D audio, etc.), such as Dolby Atmos and 360 Reality Audio, are attracting attention. The number of songs distributed by streaming services is increasing, and compatible devices including headphones are gradually being prepared, but the format called "AURO-3D" is very highly evaluated by engineers and musicians who are particular about sound. It is. WOWOW is focusing on experimental projects called "real-time live distribution" utilizing this Auro-3D. In addition to high -resolution, it is an attempt to use the surround format so that you can enjoy a more realistic live distribution at home. For two days on January 11 and 12, a live distribution was conducted as a demonstration experiment from Hakuju Hall in Shibuya -ku, Tokyo. I would like to report the pattern in the media integration lab (MIL) in Meguro-ku, Tokyo, where AURO-3D can be played in a full environment. The environment where you can watch AURO-3D at home is still limited. In addition to the corresponding AV amplifiers such as Yamaha and Denon, multiple speakers including the ceiling are required, so the difficulty of installing is not low. Please refer to the report of Mr. Masao Yamanouchi, which was released earlier for a system that is relatively easy to build at home, but here, "If you play AURO-3D in the finest environment, you will be regenerated in the finest environment. I want to deliver it on the theme of how far the world can be reproduced. ■ Focal embedded speakers "CI" constituted a multi -channel in the rakugo -kun, a rakugo artist, Hayashiya Takehei, which was held on January 11. It is a very rare attempt to distribute rakugo with high sound quality, but from the conclusion of the actual experiences, the storyteller's unique way of taking it and the drawing of the characters are subtle, not only in the expression of the voice. It was composed of a sense of air, and in Immersive audio, I was able to feel the reality and reality as if I was enjoying rakugo with other visitors at the venue of the vaudeville. The media integration, which runs this MIL, also has imported and sells audio equipment, and is particularly focused on French focals. All Mil also introduced a focal ceiling / wall mount speaker "CI". Among the focals, the Hi -Fi speaker handles a CI line that is in charge of importing Luxman, and the media integration is used for home theater, etc., and a professional line that lineup of active speakers for the studio. 。 In MIL, the focal "CI" is prepared for all 64CH, and the listener is literally "surrounded by spherical" from 360 degrees. If you look at the picture, it may look like you took it with a fisheye lens, but it is actually a sphere -like speaker. AURO-3D, but also Dolby Atmos and 360RA, etc., are unusual in Japan. AURO-3D is a major difference from Dolby Atmos, while Dolby Atmos is an object-based, while auro-3D is a channel-based, and the sound source that regenerates the speakers of each channel is corresponding. ing. Therefore, it is necessary to strictly set the speaker, but there is also the advantage that the creator's intended sound source can be reproduced as it is. Auro-3D channels are broadly divided into three layers, so-called surround layers (the height of the ears, the same as the normal surround system), high layers (upwards, upper positions of surround layers), top layers (so-called so-called). It consists of three layers of the ceiling. Of course, this MIL is embedded in the lower direction, that is, a speaker in addition to following these three layers. Literally, the image is like a listener in the "sphere" ( * Auro-3D does not use the downward direction, but there is also a downward direction in 360RA). ■ Rakugo, comic and vaudeville music with ultra -high -quality im because of ultra -high quality! The introduction has become longer, but on January 11th, a demonstration of the undercard, Hayashiya Tatami, Makoto, Hayashiya Batakehei, and laughter comics, and the dose of voting music that usually never appeared. It was delivered live. In order to listen to the distribution, it is essential to use the "ω Player" (Mac or iOS version only), which is currently provided by WOWOW for free as a beta version. The sound source output by AURO 11.1ch digital is output from the RME "Digiface Dante", and the signal is assigned to any speaker in the "Pro Tools Mtrx" in AVID, and the volume is controlled. After that, it is amplified by a power amplifier and played with a focal speaker (decoders and power amplifiers are not so -called consumer equipment, but composed of professional use equipment that media integration has strengths). The vaudeville music is usually performed at the time of the call of customers and the storyteller, but this time it is specially shown on the stage. The shamisen may be heard in a cheap sound if the quality of the playback environment is inadequate, but in this system, the performance skills of the player who draws the moment of playing the strings and the delicate nuances of frettresses are extremely extreme. You can hear it richly. What was even more impressive was the sound of the applause of the participants, which could not be reproduced in stereo, which brought the uplifting feeling of "enjoying the stage together in the audience seats." Stereo recording has a long history of appearance, and has a background of the reality of musical instruments and voices as close to live sound, and as if they were in a live venue. There is no doubt that long -term technical studies have been sophisticated to extremely highly artistic levels, but what implemented audio brings is another dimension, a different field of reality in the field. It felt like that. In fact, when we are enjoying the performance at the live venue, what we are listening to is the sound from the whole direction of 360 degrees, including the indirect sound from the wall of the hall. I felt that the "hole feeling" was particularly more likely to be opened by these immersive audio. Following the undercard of Hayashiya Tatami, the comic artist of the livelihood (this was also very enjoyable with the performance that made good use of the sound), the event called "Ikuyo Mochi" of the Hayashiya Takeshei was performed. I have never heard of rakugo in my life so far, and this "Ikyo Mochi" is a very famous story among rakugo fans, but of course this is my first experience. With the honest person, Kiyozo, who is in love with a prostitute, Ichiichi Kazuki, the happy end of the large circle, was completely drawn into the story. Rakugo is not like a beginner suddenly speaks something, but what I understand again is that rakugo artist is a multi -player who plays the role of one person, and the character of the characters and the situation in which each character is located. , Emotions must be expressed in voice and slight physical performance. Depending on how to make a little voice and how to create a feeling of air, you will draw multiple characters such as the husband, the wolf, the servant, the doctor, and the prostitute of Yoshiwara, and inform the audience in an instant. And it was clear that such characters were not only visual but also hearing, that is, the amount of information due to sound. With this imagive sound like this, it is possible to dramatically enhance immersion in the story by conveying such "air feeling" in a rich manner. AURO-3D content is not so large yet, but there are also cases where AURO-3D is used in the 2L label Blu-ray disk and the Blu-ray version of the Vienna Philharmonic's "New Year Concert". be. In addition, I would like to expect the content of digital distribution like this time. This rakugo is now available for real -time distribution, but the "ω Player" has released 13 contents recorded in the past as beta tests free of charge. It is for a limited time until February 10, so if you are interested in Immersive audio, please apply for beta test.
