【The second update today!】

Liu Yihua's words "top fever" made everyone stunned? What does this mean?

"Fever? Brother, you are in such a good health, how could you have a fever?" Xiao Huixian couldn't help asking when she heard Liu Yihua say "a top fever".

Xiao Ruoqing and Wang Yixuan were also confused, but Zhou Shimei and Li Qingxue seemed to understand a little.

Liu Yihua smiled bitterly and said, "Hey, it's really scary! The 'fever' I mean is a group of people who like music very much and like playing music and audio equipment very much."

Xiao Huixian suddenly realized and said, "Oh, it turns out that she is 'fever'."

Liu Yihua shook his head, and had no time to stumble with Xiao Huixian, and began to install the equipment.

Of course, Zhou Shimei and Xiao Ruoqing need help.

Xiao Ruoqing held a digital multi-track recorder and said strangely: "You can record such a small thing? Or a digital device? That Yihua, don't say I'm not educated. I still don't understand what digital recording media means now."

While connecting the equipment, Liu Yihua patiently answered: "In the past, recording tapes were used to record analog music signals. The signal was wide and broad, and the noise was relatively high. To express it in professional terms, it means: the dynamic range is not large enough, the frequency response range is not wide, and the noise floor is relatively high. This is the characteristic of recording tapes."

Liu Yihua's explanation is relatively easy to understand, so all the girls nodded to show that they could understand it.

Liu Yihua smiled and continued: "Because there were many defects in the analog music signals recorded on tapes in the past, electroacoustic engineers developed digital recording media. This kind of sound source is currently recorded on optical disks or hard disks. For example, the current CD belongs to digital recording media. The signal width and breadth of the digital recording media are very wide and have very little noise. In professional terms, it means: extremely large dynamic range, extremely wide frequency response range, and very little noise floor. This is the characteristic of digital recording media."

Xiao Ruoqing suddenly asked: "Yihua, I like music very much after I arrived at the dance hall. I also have a question like Xiaomei: Why does it feel a little cold when I listen to the current CD?"

"Red and cold?" Liu Yihua smiled and said, "It's still fierce! I understand what you mean. But in professional terms, it's stiff! Of course, in some cases, it can also be described as cold and cold.

The reason for this phenomenon is mainly related to the auditory characteristics of the human ear and also to the technical means of music restoration.

It's too professional to understand. Let me give you an example: the tape is like a pond of muddy water, with fish inside, and people think it's normal to fish in muddy waters. This feeling is more natural.

But the sound of the cd is like expanding the pond, digging deeper, and filtering the water, but, how can the fish live in such clear water? What would you think if you see fish in such clear water? Do you feel it is unnatural?

For example, do you understand?”

Xiao Huixian was the first to shout: "Understand! My brother just wants to take us to fish! Okay, I haven't caught fish for a long time! My brother is right, the more confused the water there is, the more fish there are! I used to fish in the muddy water with some little beggars!"

Liu Yihua touched Xiao Huixian's head and said with a heartache: "Huixian, brother will take you to fish if you have time in the future. But from now on, don't tell other children about your past things, forget about the past! Or bury the past things in your heart, I don't want others to know about your past things."

Xiao Huixian nodded obediently, remembering the words of her elder brother in her heart. Now in Huixian's heart, her own brother is the kind of person who is taller than a god!

Seeing that Xiao Huixian was so well-behaved and cute, the girls smiled and said, "Yihua, although we are a little sceptical, we understand the basic meaning. In fact, it is just a natural and unnatural feeling!"

"Well, I can understand it so much! It seems that all the ladies are superhuman in understanding. Hey, why doesn't Miss Li Qingxue speak?"

Li Qingxue said a little sadly: "Where do I have the right to speak now? I am not your wife! Sister? You only love your sister Huixian. People think that she is not a human being, and you turn a blind eye to it!"

Khan, Liu Yihua said powerlessly: "Oh. That lady... Oh, sister, you all said that your treatment is the same as theirs! The little sister has to fight for her own happiness!"

Next, Zhou Shimei and Xiao Ruoqing began to tease Li Qingxue, making Miss Li look like a peach blossom in a while.

Wang Yixuan still maintained the coldness and duty that the guard should have. Except for occasionally looking at Liu Yihua and chuckling, she rarely interrupted the rest of the time.

At this time, Director Li in the distance shouted: "Hey, Yihua, the handover is almost done. In fact, today is just a formality. How can we point out so many items clearly? The customs comrades dispatched dozens of people to calculate for two days, but we don't have so many people!"

Liu Yihua laughed and said, "Haha, it's a business that doesn't matter anyway, so it doesn't matter if it's more or less! Hey, why do we feel like bandits who occupy the mountain and become king? Now we are counting and snatching back into the copycat? Haha, will we have to divide the spoils next? Director Li now notifies the customs people to come and drive!"

Director Li smiled treacherously and said, "Hehe, I'm going to hide it from my brothers. The customs comrades are waiting outside the door, but they can't wait! Maybe they are afraid that you will change their minds! I notified them yesterday that there was a car, and they came to the municipal bureau to ask about the situation early this morning!"

Liu Yihua fainted and said, "Hey, I'm scared of poverty! I've seen a building from the 1960s in the office building of the Hanjiang Special Administrative Region Customs. When I saw that our customs guarding the national gate was working in such a place, I felt that I couldn't say anything in my heart!

Our country has been reforming and opening up for 20 years. As the country's first window, it seems so ragged? This is really ironic!”

Director Li sighed and explained softly: "Yihua, most of the customs I have seen are like this. Now our country's import and export business is not much, so the customs in many places are actually a decoration.

These customs have nothing to do, so they don’t think that the government will allocate funds to build buildings and buy rickshaws! Many customs leaders also have to ride bicycles to work!

As for the capture and smuggling, they have no armed forces, how could they arrest them?"

Liu Yihua suddenly had a bright look in front of him, and he patted Director Li on the shoulder and smiled: "Haha, Brother Li, there is a good job, do you want to do it?"

Comrade Li was shocked and dizzy when he was shocked by Liu Yihua, and said in a daze: "Ah? What's the good job? Yihua, I see that you are more cunning when you smile. You... don't you want to play with me, right?"...)
