Miss Bach's Crab Canon

050·Natural Recording Studio (Part [-], [-]rd watch)

Recording studios have always been designed with acoustic principles in mind, but the essence is simplicity.

In a room framed by ordinary walls, roofs and floors that have not been treated, the sound will be reflected by the walls, and they will continue to reflect, reflect, and reflect until the sound decays.

But this process will make the sound superimposed and become a state called "reverberation".

And the sound from this "reverberation" is not clean and pure.Even if it is recorded, it cannot be used for music production.

After discovering this point, people who want to record began to work hard to solve this problem-thus, sound-absorbing materials appeared.

As the name suggests, the room is covered with sound-absorbing materials, so that when musical instruments and people make sounds, the sound will be eaten by the walls without reflection, and of course there will be no reverberation-this simple and easy-to-understand principle is still used today. It is the foundation on which the studio is built and an absolute must for recording.

Although there are many other things to be solved-but the first priority is sound absorption.

"So, can this thing absorb sound?" Joannis pointed to the vegetables tied to Gao Yiyu's bicycle, "This... this is called... bitter vegetables?"

"Mosaic bitter cabbage, we use it for pickling sauerkraut in our area, but it doesn't depend on it for sound absorption."

After Gao Yiyu gave the bicycle to Joannis, he went to other places.

Although this is an abandoned factory, the workers did not divide up everything when it was disbanded. There are always things that are worthless and cannot be taken away.Sauna equipment was mass-produced here, and there are still many related materials.Of course, what Gao Yiyu wants is not waterproof wood, but the cloth and plastic to pack them.

Although these things were old and dusty, they were unusable, but Gao Yiyu didn't intend to make them into clothes or anything, he just wanted to use them to decorate the walls.After tidying up bundles of them, Gao Yiyu went back to his room and started to work hard with the nails he got from the hardware store.

In fact, it is not hard work - after all, there is magic.Gao Yiyu concentrated his mind and began to feel the world - after a while, the troops flying from home arrived.

Gao Yiyu was in charge of directing, Shijiu, Miaomiao... Ashamed to say, and the pair of underwear, they all worked together, some took nails, some knocked nails, and some held down the cloth.

The cloth is not tightly attached to the wall, but there is a gap, so that the excess sound can be lost in the gap.

But it doesn’t stop there. Excess plastic, dropped cloth, wood, cotton, and all kinds of things I don’t know what they are from other places are stuffed into the gap, filling the interior as much as possible. .

Their filling, under the supervision of Magic and Gao Yiyu, kept the two walls parallel and regular.

"Does this work...Hey, the voice is not so complicated and thick."

"Well, sound absorption. But there are three types of sound we make, low, mid, and high. The mid and high frequencies are easily absorbed, which is easy to do, but the low frequencies are not. They bounce multiple times, Gathering in the corner...if you don't get them sucked properly, it becomes an extremely dull recording, worse than reverb."

Joannis couldn't understand a word, but her eyes were always on the bicycle.

"So, we have to create a little low-frequency trap, and then use some poor people's sound-absorbing methods to swallow up the low-frequency as much as possible."

"Bitter cabbage?"

"And chili."

Miaomiao, Shijiu, and women's underwear, who have been busy for a long time, are ready for a new wave of work—anyway, they eat Gao Yiyu's magic power, and they always feel like drinking water from a lake, just like a bird going to a lake to fetch water. endless...

Gao Yiyu planned out four locations - two walls on two sides parallel to each other, two for each.

First, the bamboo basket was pushed up by nails.

Then there is the bamboo basket, which is nailed to the bamboo basket after being stuffed with bitter herbs.

During this process, every inch of nails smashed into the stone mortar, and a low-frequency sound-absorbing side is prepared, the sound becomes more strange.

"Bitter vegetables... eat Bass!"

Even Joannis was keenly aware of this, and the low frequency did not keep reflecting in the room reluctantly.

But to be more precise, it is a part of eating, after all, some normal reflections are left to keep the sound full.But the part that was eaten was eaten solidly...

Bamboo baskets and bamboo baskets are woven with bamboo strictly according to the structure of warp and weft. The porous structure and the layered bamboo strips will make it difficult for the incoming sound to come out.And the bitter vegetables stuffed in it, its soft texture and gaps, eat the sound waves that come in again and again.

until they are eaten dry.

"Okay, it sounds a bit dry...but the corner needs to be fixed..."

After working on the wall, Gao Yiyu used the remaining bamboo cages, stuffed them with peppers, divided the remaining vegetables equally, squeezed them at the corners, and arranged them in the middle with nails and the worn-out chairs he found. height.

"This is called a low-frequency trap... The excess low-frequency will run to the corner and gather in the corner due to reflection, so the sound-absorbing trap is placed in the corner in advance, and the low-frequency will... can't come out."

"Can the bitter vegetables and peppers be produced?" Joannis pondered for a while, and felt the voice that had changed, "It's been a big circle, you obviously hate vegetables, and you want to destroy them in front of me... ..."

Gao Yiyu was very embarrassed: "When we can't record, we will dismantle them and put them outside."

"...Throw it away when you're done using it?" I was stunned for a second, and Joannis thought of herself on the equipment list and on the back seat of the bicycle. Will there be such a day?

"No, just eat it!"

"...you...do you want to eat me too?"

"Why?!"

Although the weird dialogues continued to be staged, after some arrangement, even the words they shouted out became thin, dry, and ordinary—all of them were fed to the bitter herbs in the corner and on the wall.

Of course, the layout of the recording studio is not over yet.

The walls on the left and right sides have been dealt with.

But before and after -- still the question.

After all, it used to be a cafeteria, and the cafeteria window on the front wall has not been sealed yet.

Not only that, but on the back wall, in order to give the workers a good mood at that time, the canteen also opened the windows quite large.

After years of encroachment, many of the glass have been broken - Gao Yiyu had to block them.Otherwise, the sound will escape, or, the noise from the outside will come into the recording studio and show up in the recording like a robbery.

But when Gao Yiyu actually started to do it, he realized that it was very difficult.

She thought it would be solved by finding waterproof wood from nearby and knocking it on with nails... However, the waterproof wood is not only rotten, but also the size is not right.If multiple pieces are used for splicing, it will interfere with the sound reflection-although it is not impossible to turn the interference into a good diffusion, but it requires professional calculations...

"What's wrong?"

"I have to go to the building materials market and buy some large boards to block the windows...or simply buy some bricks and cement to build them up." Gao Yiyu only understands the principle, and what he studies is music after all, not these more physical things, so he fell into a trap. In a state of headache.

"Can't we use bitter herbs?"

"I didn't buy so many bitter vegetables."

"Borrow it from your classmate's house?" a voice suddenly said.

Gao Yiyu felt that although this was feasible, it was very embarrassing.How should I put it, in order to decorate the recording studio, did you go to a classmate's house to borrow bitter vegetables to build walls?Pay it back when you run out?This is really... too weird.

Wait, what's that sound?It wasn't Joannes's sweet, drowsy voice, or meow's temperature-adjustable sound, or the percussion of a mortar, or the fabric of panties—it was Delidoori, yes.

"Why aren't you sleeping?"

"I found you guys playing interesting things, come and see. And, thanks to you, I've been recovering well recently."

Also... the prelude that was released on YouTube was mentioned in a magazine column, and her exchange post attracted traffic. The last time I watched it, the hit rate exceeded [-].Squeeze out the water, there should be hundreds or thousands of people who have heard of it, right?It did make Delidoori more comfortable.

Thinking that Deli Duoli came out to laugh at them again, Gao Yiyu asked with a snort if he could help at all.

"It's all here, let's block the wall by the way."

"it is good."

"Ok?"

"--All right."

Simultaneously with Deli Duoli's understated words, Joannis exclaimed a little, and the darkness in her vision.Gao Yiyu's first reaction was "Oh, it's over, the power went out", but then he realized that it was just the wall being blocked and the light couldn't get in, so it was dark...

Deli Dolly actually made a move... Why is it uncharacteristically, is this something like a severed meal, family members suddenly caring, and friends suddenly contacting?

"Meow meow."

"Ok!"

At this time, modern people will take out their mobile phones - but Gao Yiyu has magical powers.

Like fireworks on a summer night, Miaomiao burns herself, illuminating everything.

Gao Yiyu first went to the front wall and found that the canteen window was sealed by thick, complete and transparent glass.Not only that, but the dilapidated door next to it also transformed into a beautiful, modern white wooden door.

Damn, why are there still rags, bamboo baskets, and bitter herbs on the other walls?Wouldn't it be nice to have a great recording studio by the way? !Is this some kind of mockery?Woo... Gao Yiyu turned his head again, wanting to see what kind of building materials blocked the windows on the wall behind.

"……Uh?"

But—she couldn't believe what she saw.

That's not a building material, or even a material, exactly.

— but life.

A big tree, which pokes its dense leaves through the window, uses the natural pulsation of branches and green leaves to fill the last gap in the recording studio.

"You still lack an acoustic diffuser here, I'm trying to cater to your natural recording studio... Heh."

"You just laughed at me?!"

“In short, I changed the history for this place-‘Next to the recording studio, there is always a lush laurel tree, and its leaf distribution is like a miracle, which meets the acoustic design they need.’”

……

ps

(Sorry for being late! ... It seems to be familiar, but it’s late again!

The head of the code word code is big, I wanted to secretly lose 1000 words in a certain chapter, but I found out why there were 1000 more words...

Anyway the idea came from bonemeal...

In addition, this month began to collect blades! )

uh...a little fever

I really didn't expect this to happen, I wanted to have a good time today.

Recently, the weather is dry and the eyes are dry looking at the computer. I bought a humidifier specially. As a result, I feel dizzy when I wake up and use it. I measured it, good guy, it’s quite hot...

I don't know if I didn't sleep well yesterday, I kicked the quilt secretly with my heels and hands together, but in order not to let me find out, I quietly covered my hands before waking up, so I caught a cold.Or the humidifier...

In short, I wrote a little bit and continued to write tomorrow. The medicine has been just right, at least it won’t get worse when I wake up tomorrow, and it can be improved after a long time.It's really shameful, just said to close the blade, it's disgusting.

051. Need socket

Leaving the cafeteria exuding a subtle natural smell—oh, the recording studio, Gao Yiyu and Ioannis squinted their eyes and walked into the sunlight.

Unlike the tightly sealed recording studio, this place reminded them that it was only afternoon.

Desolation, ruins, silence - and nature.

Deli Duoli has added a touch here, and in a fictional way, has added a reality to this world.

After coming out, Gao Yiyu discovered that the tree that appeared out of nowhere was actually not close to the window of their recording studio, it was just too lush.

Lush foliage piled up, turning it into an oversized lollipop, and clung to the studio windows, but the tree itself was deeply rooted meters away.The straight trunk is tall and straight, it is hard to imagine how old it is...

"Wow, Ms. Delidoori."

"Thank you, it's very useful after all."

"Indeed, the tree is so big, and the leaves are so densely packed, it can indeed absorb and insulate sound...very useful!"

Although he felt the gold coin in his hand sneered for a while, and seemed to have some hidden plans, but Gao Yiyu didn't care, because the scene in front of him was really spectacular.The existence of this tree alone makes the whole abandoned factory wonderful, as if this barrenness exists for it.

and--

"It's a bit fragrant." Joannis also expressed her thoughts.

Of course, she didn't sigh at the smell of shower gel on Gao Yiyu's body, let alone made coffee, but simply commented on the faint smell permeating the air - the smell from that tree.

"The laurel tree is here, it seems to be some kind of spice..." Gao Yiyu pondered, the name of the tree sounds quite artistic.

She approached the laurel tree without intending to hurt it, but gently lifted a leaf, put it between her pursed upper lip and her straight nose, and sniffed it gently.The emerald green leaves are plain in shape, but they exude a familiar smell to Gao Yiyu...

Unknowingly, Yoannis also leaned over - but unlike Gao Yiyu's approach, she directly plucked off a leaf...

"You're quite...delicate."

"The Lord warned us to love nature, but the Lord also gave us all things to use, so that we can live and enjoy life. Therefore, taking the necessary parts from nature does not violate anything."

"Then what are you going to do with this leaf?"

Joannis pinched the stem of the leaf, using its greenness to cover her smile: "This is a spice, of course it is used to make coffee."

Gao Yiyu instinctively remembered this, and wanted to go home and use the computer to look it up—but then she thought, she has a smartphone... She quickly took it out and looked it up, and found that laurel is really a spice, and it has been used for a long time.

Although its scientific name is bay leaf, it is called fragrant leaf here. If you want to marinate or burn something, you will throw a few pieces into it. powder to use.
