Ryuichi Sakamoto "The Best of'Playing the Orchestra 2014'" High resolution distribution starts today!

this time "Normal high resolution" and "High resolution for LP" Please enjoy by referring to the high-resolution listening comparison commentary by mastering engineer Seigen Ono, who was in charge of mastering the two patterns.

A: The Best of'Playing the Orchestra 2014' [Normal high resolution]
B: The Best of'Playing the Orchestra 2014' EQ'd for LP [High resolution for LP]

A [normal high resolution] 5.6MHz DSD (or 192KHz 24 / 32bit WAV) is the basis of B [high resolution for LP] = EQ'd COPY for LP cutting.
B is A with adjustments such as (1), (2) and (3).

Cutting is to physically cut the sound (waveform) into a race (groove) on the lacquer board (aluminum disk coated with lacquer) that is the basis of the record.
The characteristics of LP records are the points (4) and (5) for digital media such as CDs and high resolutions that can record and play back basically any sound.
A record that can be pressed from a lacquer board through a stamper (physically one by one) is a record that has physical restrictions (the time axis corresponding to the sampling frequency is infinite, but the frequency characteristics are 20Hz to 15KHz, and the dynamic range. Is small) by a veteran cutting engineer to keep it musically above
Make adjustments such as (1), (2), and (3). This can be pre-computed and finished during the recording, mixing or mastering process.
B [High resolution for LP] is the sound for LP record before it becomes LP record.
B is the sound adjusted in (1), (2) and (3) below, but it is natural that the noise in (4) and (5) is not included. It is the world's first attempt to hear and compare both A and B.

(1) The ideal recording time is about 18 minutes on one side for an LP record (33 rotations, 12 inches). If it is 15 minutes, it will be loud, and if it exceeds 23 minutes, the volume will be low, but since there is a pianissimo part in classical music etc., it is possible to cut it for nearly 30 minutes.
When a loud noise comes in, the race (groove) is deep and the cut is wide, so it is necessary to widen the interval so as not to straddle the next race. If it is wide, the number of lines that can be cut on the surface (although it is one) will decrease, and the recording time will be shortened. The larger the volume, the better the S / N. It is a conflict between recording time and volume.
Since the board area does not change, it is important to keep the dynamic range in a reasonable condition. If there is a sudden loud noise, you have to open the race interval.
Therefore, I use a limiter or manual to suppress peaks that do not cause any problems with CDs and high resolution. Relatively lift the pianissimo part
Therefore, the S / N of the LP record can be improved accordingly.

In addition, look at the vinyl. The first song is on the outside of the board with a diameter of 30 cm, but the last song is on the inner circumference, so it's only about 10 cm diameter. Since the number of rotations is the same, the linear speed is about 4 times different.
For pop and rock, loud is preferred, so for clubs such as 12 inches, there is a song that uses only the outer circumference for 5 to 8 minutes.
As you can see, the inside, where the amount of information is physically small, is less likely to have bass and volume than the outer circumference, and distortion increases. Based on such characteristics, I think about the composition of the last song on side A and the first song on side B (sound is good).

(2) The sound with the bass spreading to the left and right is called the opposite phase and causes distortion and needle skipping.
It is physically impossible to move back and forth, such as cutting and record needles above the board. B [High resolution for LP] is adjusted so that the low range does not spread too much.

(3) The record can only contain about 15KHz due to its frequency characteristics. Consonants, Sashisuseso = S, P, T, K sounds are high-frequency sharp waveforms that will be distorted if cut forcibly.
I will. Low level consonants are fine. In B [High resolution for LP], the area where the band is strong in the high range is rounded off. Use a de-esser or EQ (equalizer) to make adjustments. This is why it is said that records are actually warmer and thicker than CDs.

When I play an LP record
(4) Did you know that when you play a record, the impression of the reproduced sound is quite different depending on the cartridge?
So which one is playing with a waveform close to the original master tape? The "DL-103", which was jointly developed by DENON and NHK for broadcasting stations, is for broadcasting stations, so even if it has clarity, it is a sound that is not dramatized.
I will avoid giving the model name, but SHURE, ortofon, and audio-technica have their own characteristics. Audio is something that listeners enjoy playing, so which is correct and which is incorrect
There is no. All you have to do is choose a cartridge, speaker, headphones, or amplifier that will play with your favorite tone.

(5) You will hear a crackling sound (even during the song) before the music starts. This crackling is not included in the original master tape. Recently, there is also the addition of needle sounds to the mix.
No matter how well you do (1), (2) and (3), it is physically almost impossible to cut a groove in the lacquer board and make the outer circumference good and no distortion to the inner circumference (faithful to the master tape). ..
