    Discussion on fever technology

    The issue of fever is a technology, and you may not have any objections. Because it is originally through the means of technology to achieve the restoration of sound and artistic appreciation. Both

    However, first of all, we must consider how to actually reproduce the sound. Modern Hi-Fi audio technology believes that the ideal equipment should be a set of faithful to the original sound source.

    No system, no matter in the texture, sound field, dynamics, volume, range, etc., the playback should be restored to the same as the sound source, so that the appreciation of art is the same as when recording.

    Sound effect. Therefore, true Hi-Fi audio equipment and its working environment must be purely linear and distortion-free for the full range. Modern audio technology mainly includes: sound

    Recording editing technology, signal storage technology, signal conversion technology, amplification technology, control technology, architectural acoustic technology. Based on this, I think fever, I think for the enthusiasts

    The following types of fever should be included:

    Production and machine
    As far as its development is concerned, it can be said that history is the most "long". Half a century ago, the sound technology was fully established with the theory of tube amplifier technology and electroacoustics.

    It has matured and there have been many famous amplifiers. The concept of two-channel stereo has been proposed. The 300B push-horn speaker is popular in the cinema after World War II, and it became Hi-Fi at that time.

    Milestones. In the late 1950s, due to the development of negative feedback technology, the distortion characteristics of the amplifier were further improved, which became the object of electroacoustic system design. Transistor appears

    Since then, the amplifier has brought about a "revolution", making Hi-Fi audio universally enter the home of ordinary people, new design ideas and technical applications emerge one after another, with transistors

    With the continuous improvement of device manufacturing technology and the emergence of digital technology, Hi-Fi technology has completed the transition to DAA mode by AAA in the 1990s, and gradually developed into DDA.

    trend. With the development of the amplifier technology and the improvement of the level, the whole set of electro-acoustic equipment has also been greatly developed, speakers, speakers, wires, sound storage media, sound pickups

    Pieces, tuning equipment... increasingly perfect, two-channel technology has been developed into multi-channel, making the holographic stereo proposed in the 1970s gradually become a reality. Also showcased more for DIY and motorcycles

    Wide space.

    Although audio technology has become non-mainstream in the development of electronic technology, some technologies have become "antique", but due to people's pursuit of Hi-Fi, these technologies are still produced by enthusiasts.

    The rich wealth of the machine. As a certain audio master said: "Why is this old-fashioned technology still fascinating so many people today without being outdated? I think there are

    The two reasons are not negligible. One is the rise of new acoustic aesthetics, which leads people to appreciate this ancient technology product from a new perspective; the second is this ancient

    The function of the old technology product is not how fast it can fly in the sky, or how fast the information is calculated. It is used to appreciate music. Because of this, I believe in this ancient

    The technology product will not fall behind in 50 years," because it must have another new sound aesthetic every time to make it not fall behind. Therefore, when designing,

    When producing and selling this kind of audio products, the cultural background and the taste of art become very important... Anyone from any country who is engaged in the audio industry will definitely turn him into a sound.

    The cognition of music is expressed in the characteristics of the sound; it will also reflect his artistic taste in the design of the styling."

    Some people say that using DIY and motorcycle to have a fever is an "engineer complex", which is a bit reasonable. Anyone who does not design and produce for himself realizes the ideal of the heart and achieves a voice.

    Excited to appreciate the goal! From a technical point of view, it is also fundamentally different from the design and production made by the manufacturer for the development of products. DIY and motorcycles are implemented by enthusiasts.

    After a process of overcoming difficulties, the joy of the concept of accomplishment, purpose and harvest is incomparable. At the same time

    The development of parts and materials also provided a stronger material foundation and support conditions for the enthusiasts of DIY and motorcycles, which enabled them to get more in the peak of Hi-Fi climbing.

    help.
    Fever recording

    Limited to China's national conditions, the "recording party" among Chinese enthusiasts is the least common family (at least I feel like this). According to the development of Japanese enthusiasts, "recording

    The "fans" must appear after the fever level of the whole society is quite high. From the late 1960s to the early 1970s, Japanese audio equipment manufacturing has entered the international level, promoting

    The formation of a fever boom in the society, the transistor made the recording smaller, the cost of equipment reduced, and promoted many enthusiasts to join the recording ranks, and launched a "recording concert"

    Organized recording activities such as "returning to natural recordings", listening to works, commentary and awards, etc., thus forming a "recording party" enthusiasts.

    Recording enthusiasts have a keen sense of hearing, a rich sound experience and the power to appreciate sounds. They can better understand the effects of sound effects on human emotions, and they can better grasp the sound effects.

    The real "golden ear" in the fever industry. Some people are comparable to the techniques of sound engineers and tuner. Recording enthusiasts are called "photographers" in the fever industry. Their main interests are: 1. Experience

    The difference between live sound and recording and reproduction, cultivate the ability to grasp the sound phenomenon, faithful to the original sound, and make it artistic. Pay attention to the sound, scene and personal emotions in the recording

    Together, they pursue the individuality and richness of the work, and interpret the sound through recording equipment and techniques. 2. Conducting recording techniques and technical research, gradually developing

    His own recording expertise to reflect the pursuit of sound. Many of them are not satisfied with the book and the existing recording technology, often in order to achieve a certain sound effect, out of "wonderful

    Monsters, and have a special understanding of the recording position, recording method, tuning method. 3, DIY or playing recording equipment, making their own special recording equipment. I used to

    Japana€?s a€?Wireless ??¨ Experimenta€? magazine has seen an 8-channel 4CH portable mixer made by Japanese recording enthusiasts. Its design level is no less than any professional tone today.

    Sound station. 4, recording montage is the main means for recording enthusiasts to finally produce works, but also their concentrated expression of human-natural feelings and artistic ideals. some

    Add music to the natural sound, some connect the music pieces, some pursue the "colorization" of the sound, and some even use the natural sound to compose the work, etc.

    Odd. If someone uses more than a hundred turbulent recordings to create a "sound" work, and so on. 5, the recording works as an expression of their own realm, on the recording

    Appreciate and exchange products, collect works of other recording enthusiasts, burn good recordings, conduct comparative research on recording expression techniques, and cultivate your own recordings.

    Appreciation ability. 6. Write the experience and articles of the recording. In particular, the recording experience and experience of some scenes have left a valuable asset for the development of the recording level.


    Recording enthusiasts are a very high group in the fever industry, both in terms of overall level and fever literacy. Their appearance will definitely contribute to the development of fever technology.

    The role. At present, with the general improvement of China's fever level, the development of new recording methods and computer applications such as MD, the quality of audio equipment is constantly improving, and people's income has increased.

    The lengthening of leisure time and the improvement of traffic conditions have already prepared conditions for the emergence of Chinese recording enthusiasts. Although we have not yet participated in the "recording concert", but

    It is natural recording, recording montage, etc. It is still very promising. how about it! Would you like to try the fun of recording enthusiasts?

    Home audio engineering

    It mainly includes three aspects: listening room design and decoration, audio equipment configuration and tuning technology.

    The listening room is the working environment of the audio equipment, and it is also the key link of how the sound effect is realized. Some enthusiasts even think that its quality is related to whether the sound can be correctly restored.

    Basics, more important than the effects of amplifiers and speakers on sound reproduction. The sound processing of the home listening room is mainly to control the standing wave of the room, reduce the phenomenon of sound interference, and obtain appropriate

    When the reverberation time and equalize the sound field. The properly handled home listening room should have a good performance on the frequency response, sound field reduction, and sound pressure balance of the sound, so that people have a scene.

    Feeling, I dona€?t know if I am in the snail room. Because the living environment is much smaller and more diverse in shape than the music hall, there is no good architectural acoustic design, and the standing waves are audible.

    The threshold is easy to be disturbed by the outdoor environment, and the decoration must conform to the aesthetic requirements of the home. The handling conditions are harsh, and many processing techniques for the hall audio cannot be simply applied.

    It also creates conditions for enthusiasts to carry out architectural acoustics practice. Although the chances of renovating the listening room are not many for one person, you can gradually start from the living room and the warehouse.

    In practice, sum up and exchange some experiences, learn more about the principles, and wait until the conditions are mature, then proceed to design and decorate the special listening room.

    The prosperity of the audio market, magazines and exhibitions has brought great convenience to enthusiasts in accessing excellent audio equipment. There are many brands of enthusiasts for equipment in Europe, America, Japan and other countries.

    The performance is like a few treasures. I know the sound effects and music performance produced by various equipments. I can compare the subtle differences. The audio equipment configuration is already a Chinese fever today.

    Friends have the most discussed "hot topics", but to configure the equipment is not something that anyone can do. Use a variety of equipment to configure a good musical sense

    The system is a highly skilled technology. It is not only familiar with equipment, but also has good ears. More importantly, it is necessary to make good use of equipment and have a high artistic taste. If

    The material matching process is not good, even if it is high-grade goods, when working together, the effect is often frustrating; and many of the equipment that seems to be flat, after appropriate

    The match can still make a good sound, depending on whether you know the goods. Of course, to do a good job in equipment configuration, you have to consider "silver two", only in terms of your own economic conditions.

    In the case of weighing, it is most reasonable to choose a satisfactory configuration. So how do you achieve this goal? Improve the appreciation by evaluating the effects of different equipment configurations

    Literacy, continuous accumulation of experience is the right way, hearsay, closed doors, blind pursuit of famous brands is ultimately difficult to succeed.

    In the home audio project, the school sound is a long process that seems easy and difficult to do. You must first establish a calibration standard for your own purposes, so that

    You can objectively evaluate the sound system's faults, start with equipment tuning, improve the acoustic characteristics of the listening environment, repeat patient adjustments, summarize experiences, and improve control.

    Equipment and the ability to overcome environmental defects, gradually approach your ideal goal, to create the sound effect you expect. There is a lot of knowledge that can be learned in the school sound, speakers and other equipment

    The placement is very knowledgeable, and the way to overcome the ambiguity of listening to the environment should be summed up in the adjustment, and even help to improve your listening ability. In short, if you pursue Hi-Fi

    Perfect, the school sound will always accompany you through the road of fever.

    With the development of audio technology, electronic technology and digital technology, the equipment we use today is designed, manufactured and developed in accordance with the idea of a€?a€?Hi-Fi. Therefore, fever equipment

    In pursuit of Hi-Fi as the only standard and its soul, even the production of sound control equipment, it must be functionalized under the premise of ensuring Hi-Fi. today

    The frequency response of the amplifier can reach 100kHz (the low noise wideband amplifier has reached the DC-2MHz), the total distortion is less than 0.1%, linear, transient, and letter

    The noise ratio and other indicators are close to the overall requirements of Hi-Fi, and are developed in the direction of personalization under the influence of Hi-End thinking; A/D, D/A signal conversion can be almost technically achieved.

    Arbitrary precision; 32CH multi-channel digital recording basically realizes the control of full sound field information and original sound recording; ultra-large amount of optical information storage technology can achieve more precise voice information

    Non-destructive storage and extraction; the development of sound control technology is more colorful, using DSP and other technologies, can change the strength, phase, harmonic components, frequency of sound signals according to needs

    Rate response, transient performance, etc., provide great convenience for processing sound effects; through the combination of architectural acoustic technology and multi-channel playback technology, the sound field reduction in confined rooms

    There is no longer a problem that is difficult to solve. It is no exaggeration to say that using the existing technology, it is possible to re-create the original sound according to its own needs (for example, some DJ pairs).

    The production of sound effects, the personalized matching and adjustment of some audiophiles to the audio system), thus promoting the development of audio to the art direction. Although the current level of technology still needs

    Perfect, there are still speakers and so on, which have been slow to develop and have not solved the problem.

    Similar to photography, acoustic reproduction of sound is achieved in a passive manner, which is more restrictive to artistic creation. And, due to economic and other conditions, most of the country

    The number of equipment owned by a few enthusiasts is very limited (almost all have only one set of equipment), and there are few different equipments that can be used in listening and listening. The scope of aesthetic realization is narrow, so they

    The main concern is only the signal conversion technology, the amplification technology, etc. to achieve the problem of sound reproduction, from the perspective of pure technology to understand the sound. Especially the traditional view of Hi-Fi

    The influence of the mind, many current enthusiasts do not think that sound can be used as a means of artistic creation, but as a tool to reproduce sound. It should be said that this kind of situation

    Compared with foreign countries, it is still at a relatively preliminary stage in terms of comprehensive understanding of the technical nature of sound.

    Adhere to the "sound is the uniqueness of technology" people believe that: audio is only the only technology, to ensure the purity of Hi-Fi concept. However, this idea is the ideal master from the beginning.

    Righteous! As long as the technology remains to the forefront of the nonlinearity in the sound system, it is impossible to achieve. Therefore, this view has been severely challenged. First, electricity

    There is no pure linear amplifier in the theory of the road, and the audio circuit is not the mainstream of the development of electronic technology. It is difficult to make a big breakthrough. Second, since the emergence of Hi-End

    The development of audio systems has been personalized to meet the realization of people's aesthetic concepts in the use of audio; third, as society becomes more secular and commoditized, people are

    The use of sound for sound appreciation also presents a variety of requirements. If such a situation continues, Hi-Fia€?s idea of a€?a€?"true" as the sole evaluation criterion for sound will be disintegrated.

    . This is also the case, although the pursuit of sound to restore the sound of the sound will continue, but more people will turn their eyes to the psychological experience of listening to the sound, so that the sound of the sound

    The sound reproduction is more artistic, more in line with the goal of its own aesthetic realization, to maximize the utilitarian and efficiency of sound technology, and ultimately surpass the use of simple tools.

    From a technical point of view, can the sound reduction of sound only reflect the original nature of the sound? In fact, the sound also contains its own performance of the sound, the so-called "

    The British sound, "American sound"... is also created using this nature, and no one thinks it does not conform to Hi-Fi, but the real voice is only one kind. Therefore,

    Everyone has compromised the sound between "realism" and "beauty". There are only psychologically acceptable questions that are not acceptable. And many Japanese-made audio, some monitors

    The sound is very "real", but everyone does not like it, and thinks that there is a lack of culture. In particular, Japanese audio has been said to have no "music flavor" and cannot be heard at all. In terms of technology,

    I believe that it is not difficult for the Japanese to make a sound with "Japanese sound", but will the market accept it? How many people can accept it? Today, the mainstream of music is European and American music, namely

    To be nationalized, taking into account the factors introduced to the world, it must also contain elements of European and American. Imagine if the Japanese put their aesthetic concept into the sound manufacturing, so

    The sound still wants to sell to the world! Then take the road of "reality", at least this is a complete embodiment of Hi-Fi, but it is very difficult to do in low-end products, and thus caused

    A piece of condemnation from everyone. Let's talk about "Chinese sound". Although it also makes the Chinese people dream, from the market, is the manufacturer willing to do it? Enthusiasts are not saying that Britain

    Well, the United States.

    For enthusiasts, the use of existing equipment is now the same technology as DIY. This is because of the diversified development of audio equipment, if all

    The sound is "true", then we will lose the opportunity to appreciate the diverse sound effects. Among some foreign enthusiasts, they often have more than one set of equipment, so they can

    Through the various combinations of equipment to achieve the expression and selection of sound, according to different sound characteristics to determine the appreciation of the target, so that the image and meaning of the sound is fully expressed according to their own ideals

    , in line with their own aesthetic needs. Some people even took the attitude of abandoning the "true" principle and thought that appreciation should make me happy, it should be what I need.

    . Introduce some equipment of sound control into the listening and listening of the sound, and use the method of changing the tone, frequency response, sound field, time, etc. of the sound to achieve the purpose of appreciation.

    However, in order to ensure the appreciation of the original sound, they still left a place for "truth". This can't help remind me of why the Spanish surrealist painter

    Dali wants to change the Mona Lisa into a round eye in the copy of the Mona Lisa, plus the upturned moustache. This is actually an expression of using perfection to express oneself.

    . This may be unacceptable to Chinese people who have long been accustomed to figurative appreciation, as reflected in the appreciation of sound.

    In addition, the development of computer technology will also create new technical ways for the sound expression of sound, thus enriching the aesthetics of sound.
