Taketomi IslandDSD 11.2 / PCM 192 - 24 Field Surround Recording and Music Production

The Sound of Taketomi Island Okinawa
DSD 11.2 / PCM 192 - 24 Field Surround Recording and Music Production

Mick Sawaguchi C. E. O UNAMAS-Label


In the high-res music production UNAMAS-Label, we have produced 5 albums so far with the concept of "surround scape" which collaborated with music surround and field recording which is my author's life work. 
This album is the sixth album, and the recording was done at "Taketomi-Island" on part of Yaeyama Islands OKINAWA from February 13 to 16, 2017. This island is also famous as an island that carefully inherits the traditional culture of the Yaeyama region, such as many folk songs, old songs, performing arts, traditions and customs. In this album, we planned the recording of roots music  that paerforme with San-shin and Vocal mainly about Taketomi Island and spent all the day we performed field recordings at midnight when we finish music recording at day time since became quiet. 
Recording is aimed at ecological music production and it is compact, but since it did PCM-192-24 surround and DSD 11.2 direct 2CH recording for the first time as practical use, we will introduce a backstage behind it.

1 Geography and culture of Taketomi-Island

Taketomi island is the small island on the left of Ishigaki-jima Island.

As you can see from the map, it is located in the Yaeyama Islands in Okinawa Prefecture, and from Ishigakijima, the center of the Yaeyama region, a population of 365 people (about 6 km) on a high speed ship with a speedboat (about 6 km). The flat island made from raised coral reefs leaves the original landscape of Okinawa like the red tile in the flat shop, the stone wall in the coral, the white sandy road that crushed the coral, and now it is said that it came to "Ryukyu-Landscape" anywhere in Okinawa It is a scenery that makes me realize that. The whole is designated as Iri-omote Ishigaki National Park as "an island of cultural landscape fostered by the natural environment", and the largest coral reef in Japan, stone reef lake, spreads to the west. 
In 1986, the "Taketomi-Charter" based on the conscience of the residents was enacted and the five principles for protecting the landscape and nature of the island were stated as "not selling", "not soiling", "not disturbing", "not breaking", "living" It is an island where local governance by residents is established.

 2 field recording  

2-1 Recent Trends 
Field recording is not limited to 2CH stereo recording such as stereo and dummy head recording, and recording in various surrounds is also done. The big chance is mainly a system using a one-point surround microphone and a portable recorder compatible with 4CH ~ 8CH from the needs of 3D sound such as VR AR. In 3D surround field recording, there is no decision as to what kind of miking is effective, but everyone who is doing 3D field recording devises themselves and combines 4 recorders with 2CH built-in microphones in upper and lower arrays 8CH recording .Or We can see examples of real 4CH ~ 8CH microphone arrays assembled from upper and lower.

A one-point surround microphone corresponding to a new AMBISONIC has appeared, as this trend of 3D sound boosted also to the one point surround microphone applying the AMBISONIC coding technology that was used mainly in Europe. In the United States, a brisk manufacturer called Eigenmik has released a 32-channel one-point microphone, and a well-established Sennheiser also released a new product of a one-point surround microphone too.

2-2 Field recording in Taketomi Island 

The authors' field recording system does not record natural sounds as ambience, but from the feeling that we want to record surround sound as a realistic sound image, the main microphone is based on 4CH which used the Sanken CUW-180 XY one-point microphone for the front and rear I am doing it. CUW - 180 has exclusive basket - type windshield + windjammer, so it is safe even at the beach and so on. Since products of other companies do not have heavey duty windshield accessories that have kept their attention to it, we must search for a draft shield that conforms to the specifications separately. The recorder is a 4CH recorder called SONOSAX SX - R4 based on the recording in 192 - 24. Late night recording scenery is like this.

 In the recent ZOOM F - 8CH recorder etc, the internal memory is up to 512 GB and its capacity is large and safe for long - term field recording, but the SX - R 4 is a type that mirrors the 60 GB memory with HD and CF so long - range location It is necessary to bring a PC separately and back up the data and empty the memory.

In field recording in surround, we have to find a point where it is likely to be able to record a uniform sound field at 360 degrees, not only in the front, so we did a location scouting in Taketomi Island during the day to find out where the sound is Keep on going to the site late at night I recorded.  where the traffic (from the high speed boat using Ishigaki Island as a hub flies to the Yaeyama Islands every 30 minutes so that the engine sound roars throughout the island and you can not record during the day!) Since it is flatland coral reef raised island, I fixed 2 deferent locationpoints.

● Beach of coral reef rocky beach and sandy beach behind a tree.
● Tree trees and winds they were deco, banyan mullet, banana field is.

Surround miking at the beach How to capture the sound of the beach is the person who records. The author prefers a sound field that brings out equipment up to the offshore a little bit if it is a shallow beach and like a sound field where the waves expand at 360 degrees, but the coast of Taketomi Island has many coarse rocks of coral reefs I installed a microphone on the edge and lowered the front toward the waves and the rear microphone aimed at the reflected sound of the waves facing upward. In another place, the back of the sand beach was trees with trees, so the front and rear were same level with the front, the front was a wave sound, and the rear recorded the contrast such as the wind sound of the trees and the voice of the local owl.

A tree roaring In the trees with thick leaves of Deago and mangroves, we found equipment surrounded by trees, set up the equipment at the point where you can hear the wind and trees roaring at 360 degrees, and both the front and rear It is installed upward. In the banana field and prairie, etc, I recorded with aiming at the sound the leaves shake. With a combination of independent microphones that are not a one-point microphone, it is advantageous to have a change degree of freedom from horizontal installation to upward, downward, or a combination of these depending on the situation of such a recording location. The photos to introduce are mostly photographs taken during the day's location hall, but please refer to it.

 3DSD 11.2 Direct 2 CH and PCM 4 CH Music Recording 

Roots music of Taketomi Island has a simple composition of basic Three lines San-Shin and songs, but this time, Mr. Maki and Yamazaki of the line producer have changed Ocarina, Flute, Ohayashi and Taiko We recorded a total of 11 songs at the public hall . In addition to the 192-24 PCM recording by Pyramix DAW which I constantly use, this time, the system prepared by music recording is DSD 11.2 direct 2CH recording by RME's new product ADI - 2 Pro I did it in parallel. The recording system diagram is shown below.

 My Miking of PCM recording is the main Sanken CO - 100 KX 2 CH + Ambience Sanken CUW - 180 X 1 2 CH This is eventually records a lot of air feeling like natural sound surround . One DSD 11.2 is a simple configuration of direct DSD recording from the interface of RME ADI - 2 PRO using unidirectional A - B pair BLUE Bottle Rocketx 2 so as to be established only by music. Especially regarding Asadoya-Yunta , listening to the story of Mr. Maki that all songs have not been recorded due to time limitation so far, let's record all the songs I made a complete recording up to the 23rd peace.

4 From the one stop editing in the same DAW of the DSD file to MIX 

There was not a standard work flow which can produce one stop from the recording to the final master so far for the DSD recorded sound source. (If you record with DXD from the beginning, you can complete it with a one stop.) Therefore, experienced people also give various wisdom in how to compromise with sound tracks recorded by multitrack, editing OK take of music, reverb addition and processing It is the present situation that it is. Since it was upgraded to Pyramix ver-10, it became possible to create a DSD master with a one-stop workflow with the following two types.

Proposed-01 All done with PCM DXD converted final data, converted to DSD by DSD converter 

Proposal-02 At the stage of MIX DOWN, use the "CD- SA. CD data creation" function, create the required file format at a stroke by using the function "Album Publishing" in Generate CD Image . 

In the case of original recording with DSD, we used the plan -02 to create DSD data in one stroke using "album publishing" function, 


In accordance with the diversifying listening style, the distribution master provides files using 2H and MQA coding files as well as binaural coding technology HPL for headphone audiences, in addition to surround . 

In Japan, from e-onkyo music also,worldwide,

furthermore DSD 2CH master will be released from RME Premium Record and MQA-CD as OTTAVA so please enjoy in various formats .
