Gong Hui was not discouraged at all, and the path she believed would continue firmly.

"Master Ming, please be sure to help me test it. I am willing to pay for how much you want."

"I don't want a penny, and I don't test it. It's just a waste of time. I'm working on it, so you go." A skilled person has such a temper. If he is not focused enough, he can't be so skillful.

Gong Hui saw a small speaker on his desk, and when she was anxious, she turned her head and connected the MP3 to it. Soon the melodious music floated out, but it was very noisy and it was hard to tell whether it was good or bad.

"Master Ming, you also know that I have purchased Gumei Electric Appliances. I don't know how many MP3s I've seen. This product is really different. Otherwise, why would I ask you to test it? It's not an unnecessary move. Please believe me. I'm very anxious now, please help me."

Mingyuan finally raised his head, thinking that you, a woman, are very annoying, do you know, so he reached out to turn off the speaker, then took the MP3 and looked again, frowned and looked unhappy, and said, "Hey, you are so annoying, I only have five minutes to show you, I don't understand you, what's the point of testing this broken thing?"

Directly use the headphone interface to pass the analog signal out, a signal enhancement device, and then enter the oscilloscope. You will know it after analysis. Take a brief look at the frequency domain response, which shows whether the relative size of the sound signals of each frequency played by the player can still maintain their original appearance.

Mingyuan was originally careless and said, "Look at how trash..."

I was stunned when I saw the frequency response curve and stared at me and stopped talking.

Gong Hui didn't know what the line above meant, and she didn't dare to ask, for fear of annoying the skilled man.

"My grass is actually a straight line!" Mingyuan stared at him and murmured in his mouth.

Then he pressed MP3 for a while, then pressed the oscilloscope for a while, and that straight line appeared several times. Gong Hui was very anxious and couldn't help asking: "Master Ming, what does this mean after all?"

It was like the sword-casting master saw a more awesome sword and said excitedly: "This thing is really extraordinary."

"Master Ming can explain it more clearly?" Gong Hui asked timidly.

"It's so annoying. Have you seen this straight line? A good frequency response is that a stable enough signal can be output at each frequency point, and the signal sizes between different frequency points are the same. However, the low frequency and high frequency parts are more difficult to reconstruct the signal, so there is usually attenuation in these two frequency bands."

Gong Hui felt that she was very big.

Fortunately, Mingyuan continued to explain, "The better the output quality MP3, the smoother the frequency response curve will be. On the contrary, not only will it attenuate quickly at high and low frequencies, but it may also jitter in general frequency bands. Can you see, this little guy's curve is almost a straight line without burrs, which is simply a burst of pain."

"My grass, who did this? Yinba is really crazy, but there is this capital crazy."

Although Gong Hui seemed to understand it, she still understood that the technically confirmed the super sound quality of this product, so she felt relieved and hurriedly thanked, "It's so troublesome to Master Ming, thank you, I won't disturb your time."

Mingyuan reached out to protect him and said anxiously: "What's the hurry? I'll take a look."

"Uh, don't you have only five minutes? Why don't I come again tomorrow?"

"You woman is so annoyed, let me study it again."

Gong Hui opened her mouth wide in surprise. This person was so strange.

Mingyuan was completely excited, took out several MP3s, copied the same music in it, imported the same source file, and said to himself: "I see that it is one level higher than the highest-end Moonlight Treasure Box, which is comparable to Aili and the sound quality king. Let's take a look at other parameters."

Gong Hui was also shocked, not expecting that this little thing was stronger than she expected.

"The local noise is smaller, the dynamic range is wide enough, the harmonic distortion rate is almost no 1000Hz, the intermodulation distortion is perfectly solved, the stereo separation is ridiculously strong, and there is no crosstalk at all..." Mingyuan popped up a parameter in a while, and conducted detailed tests and comparisons with several products.

Gong Hui stood beside him and looked at his crazy state, talking in his mouth, and becoming more and more excited.

"Excellent, amazing, this is a god-level product. The person who developed this product must be a god-like person. What kind of hardware is it made of? Is Philips' latest chip? Cao, why did you get such a shell? What kind of prank is it? Oh, can I take it apart and see?"

Gong Hui was stunned. She was so powerful? Who did this? It could never be that hippie man!

Mingyuan quickly opened it apart, and couldn't wait to break it apart and screamed, "My grass, it's true, sigmatel, are you teasing me?"

Gong Hui came back to her senses and adapted to the shock of this skilled master, "Master Ming, what's wrong?"

"Look, is this still a human?"

Gong Hui looked at it and found that the circuit board layout inside looked very beautiful and couldn't tell anything. She looked at it carefully in a daze, but was embarrassed to ask, and she didn't speak for a long time.

"Master Ming, is there anything wrong with this?"

Mingyuan's expression is, are you an idiot? He explained disdainfully: "Look at the black main control chip, sigmatel, do you see it? This thing is a mid-to-low-end chip, and it actually produces this sound quality. The guy who developed this product is simply not a human being. Who is it?"

"I don't know who developed it."

Mingyuan said anxiously: "What are you doing? You don't know who is holding someone's products? Isn't this what Yinba Company said? I've tested it for you for free and have the chance to let me meet this great god."

OK, I will do my best.

Gong Hui agreed.

Mingyuan couldn't put it down. After fiddling with it, he changed the music and tested it again. Gong Hui waited aside for a long time, but it was difficult to urge him.

Once this technician becomes addicted, it is quite terrifying and cannot feel it after several hours.

Gong Hui stood aside so stupidly until Mingyuan reacted, looked at her strangely, and said something that almost made her collapse, "Hey, why are you still here?"

"Master Ming, please give me the MP3..."

Before he finished speaking, he was interrupted rudely. Mingyuan shouted, "Hey, I said you are not reasonable. After taking me a test, there was never anyone who wanted to go back. And I will test it for you for free."

Gong Hui also knew this rule and hurriedly said, "Sorry, Master Ming, I can give you a test fee, but please return the MP3 to me."

Mingyuan held it in his hand, as if he was facing the Lord of the Ring, and waved his hands repeatedly, "If you don't return it, you will definitely not return it. If you come to my hands, don't think you can take it back. You can't pay the test fee."

The child is holding candy in his hand, but he doesn't give it to him no matter how he coaxes him.

...
