Chinese entertainment for engineering students

Wang Fei's birthday party was not a grand event, and it did not cause any ripples. But Wang Fei is very happy, her life has begun a new chapter.

The two lived a small life in the small courtyard, getting up early every day to practice martial arts, and practicing singing from time to time. Wang Xu prepared several songs for her, which were enough for her to use for a while.

Most importantly, she began to feel changes in her own aura. At least the continuous treble no longer floats, and the bass area begins to show a stable and rounded temperament.

This time, Wang Fei really believed it. She had no idea that just drinking soup and dancing every day would have such a good effect. Since then, Wang Fei has also begun to take the initiative to practice.

She really likes singing, and this kind of skill that can make her sing better is so thoughtful, isn't it?

It's just that the boy is so tormenting every night, which makes her really love and hate him a little bit, but she can't stop.

What I love is the full sense of fulfillment every night, and the feeling of constantly flying in the clouds. I love it so much that I hope this day will never end.

What I hate is the feeling of weakness and soreness in my body when I get up every day, especially the feeling of attachment that makes me want to run away immediately, but I am reluctant to leave.

Wang Xu has gained quite a lot recently. First of all, Dong Si Wang Er has become famous, at least in the music circle.

Not because he is Wang Fei's boyfriend, but because of the two original ballads, although it is a bit far-fetched to say that "Legend" is a ballad.

However, most people who listen to songs can't tell what a folk song is. In most people's minds, anything played by someone who plays the guitar and sings it is considered a folk song.

At this moment, Wang Fei is still a bit popular among middle school students. In other places, she is basically just a passerby. If it weren't for her relationship with Luan Shu and Luan Shu showing off everywhere, most people wouldn't even know that Wang Fei and Wang Jingwen are the same person.

There are many benefits to being famous, the first of which is that the rich man increased his price. Well, 200 songs for four songs is still a warm-up, which is a very high salary.

The biggest advantage of being famous is that Wang Xu's recording studio project progress has been greatly improved. When he took Wang Fei on a motorcycle purchase, many equipment dealers could immediately recognize him.

When he was shopping for goods at the equipment dealer, people would come over to chat with him from time to time. The story of a talented and beautiful woman was considered a good story, so it spread widely.

A song stole Luan Shu's girl, and this kind of gossip spread faster than a mountain fire. Wang Xu was also aggrieved. What did you mean by snatching Luan Shu's girl? If it were a first-come, first-served basis, he, Wang Xu, was the earlier one, and his crush on her was also in love.

The equipment dealer's name is Wang Hongwu. He makes professional audio equipment in the imperial capital. He has a wide range of opportunities, including Ugly Country, Rotten Country, Denmark, and even in his childhood, he can get it.

After hearing Wang Xu's request, he took the initiative to help him analyze it and told him that since you wanted to renovate it, you might as well buy second-hand ones first.

Wang Xu was right. First of all, the replacement of audio and video equipment is not that fast, and digital equipment does not have aging problems.

In addition, it is second-hand in the first place, so it is a foundation here, and the core depends on systematic technology.

Wang Xu followed his good deeds and spent only around 100,000 to collect all the second-hand equipment needed for a recording studio. From picking up sounds and recording to splitting and bouncing tracks, it's pretty neat.

There were also some equipment that looked quite new, but had problems and no one knew how to repair them. Wang Xu took a look and collected a lot of them at the same price as junk items.

Since every piece of equipment has some glitches, the recorded content can only be heard. Don't worry, we still have to look at the follow-up transformation.

After returning to the small courtyard, Wang Xu used his free time to check it carefully. The recording equipment was among his skills.

Or how can I say that this system is weird? It is obviously an entertainment system, but as a result, things related to entertainment are extremely expensive, while items unrelated to it are very cheap, and they are often given away.

For example, when the predecessor obtained the system, he was so shameless in the lottery. Only one white skill was obtained. But when the skills were passed on, I discovered that this skill called equipment maintenance actually comes with all kinds of electronic, circuit, mechanical, and computer knowledge, plus countless circuit drawings, mechanical structures, software codes, etc. It is simply too comprehensive. .

This is one of the reasons why my predecessor chose the automation department in the end, because he didn't have to study.

But it just so happens that such an important and wide-ranging skill is only available in white. As for those singing skills, music proficiency, and other entertainment-related things, they are all from blue to gold. Who are you going to talk to for explanation?

Now that the predecessor system has been disabled, cultural and entertainment skills are stored as skills in the own system and are directly instilled, eliminating the need for learning. The other technologies that can be redeemed now are just technologies. You have to learn and try them yourself.

But this kind of trouble is really not a problem for an engineering student who has traveled through countless worlds.

Among them, digital recording equipment can continue to be used. Various music equipment is not updated very quickly. Many top recording studios still use equipment from the 1970s.

Even many equipment from the analog era are still used by audiophiles, and the hum generated by the analog equipment can sometimes become a very beautiful background sound.

This is the creativity of people who play music. Sound is sound, whether it sounds good or not. The so-called purity is a very subjective thing.

After carefully analyzing the audio, you will find that the pure sound may contain more small clutter, but these clutter is very coordinated.

Tape recorders of this era were actually analog music, while CDs were digital music. Therefore, this era is an era of modular and digital mixing.

The pickup acquires an analog signal and then converts it into a digital signal. After editing, it forms a digital mixtape. At this time, the tape is still used, but it is a digital tape, and the recorded signal is also digital.

The so-called simulation is the original form of direct music. Various waveforms of sound waves are recorded on the medium in a continuous manner.

The digital mode decomposes the waveform into square waves one by one, and forms digital music through small samples. Obviously, such sampling will have two key parameters, one is the sampling rate on the horizontal axis, and the other is the bit rate on the vertical axis.

As long as the sampling is fine enough, human ears can't tell the difference. The so-called sampling rate refers to how detailed the data is divided according to time. Today's recording studios generally use 48khz, which is 48,000 samples per second.

In fact, this sampling rate has been used since the 1960s, and it is also the current mainstream.

This kind of sampling is enough, no matter how much you try, people will not hear the difference, and it will still be mainstream even 40 years later.

Therefore, in principle, if digital tapes recorded 40 years ago can be converted to high-definition in the 21st century, there will be no problem with the sampling rate.

The bit rate in this era was mostly 16-bit, but later generations generally used 24-bit or even 32-bit, which caused a gap when some old records were converted to high-definition.

But to be honest, most people can't hear it at all. Even professionals, only a few people can hear the difference. The roughness of old records that you feel now is actually a problem with the pickup equipment itself at that time, rather than a problem with digital sampling and storage.

The result of this kind of high-precision sampling recording is that the tapes are very expensive. Each instrument has one track, and one track almost costs one tape. The price of a tape is several hundred, or even thousands for good ones.

In this era, the storage capacity of computers is still measured in megabytes. An ordinary hard disk is 40 megabytes, and the largest one is only 400 megabytes. How much data is an uncompressed audio track?

If it is 16-bit digital audio, then a simple calculation can tell that a 4-minute audio requires 4 (minutes) * 60 (seconds) * 16 (bits) * 48000 (sampling rate) = 184,320,000, which is 180 megabytes Bit. and more than 20 megabytes. In layman's terms: one audio track and one hard drive.

So editing in this era is a very troublesome thing. The data is stored on tape. If you need a certain section, you have to rewind and re-read that section. Think about the efficiency.

This is why recording studios in that era generally did not record each instrument separately, because of the difficulty of synthesis.

In the future, the memory of any notebook will be counted by G. Several audio tracks are loaded into the memory at the same time, and the software can naturally pull them back and forth quickly. In this era when the 386 was just released and only had a few megabytes of memory, synthesizing audio tracks was a tangle.

No matter what, there are only so many things on hand. If you have the technology, you also need a factory to produce it for you. Therefore, everything can only be done slowly.

Wang Xuzai carefully studied the set of second-hand equipment. First, he had to run the system, at least to the level commonly seen in current recording studios. It would be better if it could be higher.

After careful consideration, Wang Xu finally redeemed the first technology, a new type of microphone production technology.

This is a condenser microphone that is slightly ahead of the current technology. Wang Xu chose it because it comes with several basic material manufacturing processes, such as ultra-thin electret diaphragm, gate transistor, high-efficiency diode, and high-purity oxygen-free Copper wires, high-strength aluminum alloy enclosure.

That's right, this microphone, which only requires 1,000 emotion points, can bring Wang Xu a lot of high-end production technology and processing technology.

However, just having technical information is not enough. First, you have to understand and learn these technologies. Maybe you have to go to the library to look up books.

Then we need laboratory experiments, selecting existing production equipment, experimental production, and mass production, so that we can provide them in large quantities.

Although there is no way to get it right in one step, after breaking it down, there will be no problem in opening several factories in the future. Anyway, Wang Xu is not in a hurry. It is not too late to go back to school and experiment with this thing after school starts.

As for now, of course, I will continue to live a two-person world with Wang Fei. Who knows one day Wang Fei will be called back to Xiangjiang and the two places will become separated.

Wang Xu has no intention of getting too involved in Wang Fei's singing career. On the one hand, she doesn't like her current manager very much. She plans to call Wang Fei back just for him. She just doesn't like it.

The current period of time may be the most leisure time for Wang Fei in the future. Of course, she will have to get tired of it for a while. School has started, and Wang Fei will probably have to return to Xiangjiang.

Wang Xu has actually copied more than ten songs now, but he hasn't figured out how to release the song yet. At least he doesn't plan to sell himself out too early. There are a lot of songs that can be copied, and he doesn't want to give away all the copyrights.

Moreover, Wang Fei once introduced the Black Panther Band to her current manager, but Wang Xu always felt that the manager was not very reliable.

As for the quality of Black Panther's album, it actually didn't make any splash in Hong Kong. It sold 50,000 copies. On the contrary, it was only after it was released in mainland China the following year that it exploded into a terrifying influence. This can be seen from its The level of operation is just that.

In the past life of 1993, Wang Fei's current manager sold Wang Fei for 2 million. Wang Fei and the company formed a cooperative relationship, and she had control over her own songs, and that was how she became the Queen of Songs.

But now I don’t have much bargaining power, so I might as well wait, or maybe try it out in China first.
