You may not have any objections to the question that fever is a technology. Because it is originally through the means of technology to achieve the restoration of sound and artistic appreciation. Both
This is the case, then the question of how to reproduce sounds must be considered first. Modern Hi-Fi audio technology believes that the ideal equipment should be a set of faithful to the original sound source
Regardless of the system, the playback of all aspects of texture, sound field, dynamics, volume, range, etc. must be restored to be consistent with the sound source, so that the appreciation of art can be the same as when recording
Sound effects. Therefore, the 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 and editing technology, signal storage technology, signal conversion technology, amplification technology, control technology, architectural acoustics technology. Talking about fever based on this, I think for fans
The following types of fever should be included:
Production and Motorcycle
As far as its development is concerned, it can be said that it has the longest history. Half a century ago, the sound technology marked by the comprehensive establishment of tube amplifier technology and electroacoustic theory
It has already reached maturity, and there have been many famous amplifiers. The concept of two-channel stereo has been proposed. The 300B push horn speaker has become popular in the cinemas after World War II and became the Hi-Fi at that time.
Milestone. In the late 1950s, due to the development of negative feedback technology, the distortion characteristics of the amplifier were further improved, and became the object followed by the design of electro-acoustic systems. Transistor appears
Since then, the amplifier has almost brought about a "revolution", so that Hi-Fi audio has generally entered the home of ordinary people. New design concepts and technical applications have emerged in an endless stream.
The continuous improvement of device manufacturing technology and the emergence of digital technology. In the 1990s, Hi-Fi technology has changed from AAA to DAA, and gradually developed into DDA.
trend. With the development and improvement of amplifier technology, the entire set of electro-acoustic equipment has also made great progress, speakers, speakers, wires, sound storage media, sound pickups
Parts, tuning equipment ... increasingly perfect, two-channel technology has developed into multi-channel, making the holographic stereo proposed in the 1970s gradually become a reality. It also shows a wider range for DIY and motorcycle
Wide space.
Although audio technology is no longer 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 motorcycles. As one audio expert said: "Why is this old antique technology still fascinating so many people today and not falling behind? I think there are
Two reasons cannot be ignored. The first is the continuous rise of new audio aesthetics, which leads people to enjoy this ancient technology product from a new perspective; the second is this ancient
The function of the old technology product is not how high it can fly in the sky, or how fast the information can be calculated, it is used to enjoy music. Because of this, I believe this ancient
Technical products will not be outdated in 50 years' time, "because" it must have another new audio aesthetic every once in a while to keep it out of date, so when designing,
When producing and selling this kind of audio products, the cultural background and artistic taste become very important ... When people in any country are engaged in the audio industry, they will definitely match him
Yue's cognition is expressed in the characteristics of sound; he will surely reflect his taste for art in the design of modeling. "
Some people say that using DIY and motorcycle to have a fever is an "engineer complex", which makes sense. Who did n’t design and make a work for themselves that achieved their ideals and reached a voice
Appreciate the goal and be excited! From a technical point of view, it is also fundamentally different from the design and manufacture of products developed by manufacturers. DIY and motorcycles are implemented by enthusiasts.
A process of our own sound concept, after overcoming many difficulties, its joy in terms of accomplishment, purpose and gain is unmatched. At the same time, due to
The development of parts and materials has also provided a stronger material foundation and support conditions for enthusiasts ’DIY and motorcycle ideas, so that they have gained more in the climb of Hi-Fi peaks.
help.
Fever recording
Limited to China's national conditions, the "recording school" is the least common among Chinese audiophiles (at least my feeling is this). According to the development of Japanese enthusiasts, "recording
"Pai" enthusiasts must appear after the society has a very high level of fever. From the late 1960s to the early 1970s, Japan ’s audio equipment manufacturing has entered the international level to promote
In order to form the fever fever in the society, the transistor has made the recording miniaturized, the cost of equipment has been reduced, and many audiophiles have been encouraged to join the recording ranks, and the "recording concert"
, "Return to Nature Recording", listening to works, commenting and awarding organized recording activities, thus forming a "recording school" enthusiasts.
Recording enthusiasts have keen hearing, rich sound experience, and the ability to appreciate sound. They can better understand the impact of sound effects on human emotions, and they can better grasp the reproduction of sound effects.
The real "golden ear" in the fever world. Some people are comparable to the techniques of sound engineers and sound engineers. Audiophiles are called "photographers" in the audiophile world. Their main interests are: 1. Experience
The difference between the live sound and the replay of the recording cultivates the ability to grasp the sound phenomenon, faithful to the original sound, and make it artistic. Pay attention to the integration of sounds, scenes and personal emotions in the recording
Together, they pursue the personalization and rich feelings of the work, and interpret the sound through recording equipment and techniques. 2. Conduct exploration of recording skills and technical research, and gradually cultivate self
His own recording expertise to reflect the pursuit of sound effects. Many of them are not satisfied with the book and the existing recording technology, often in order to achieve a certain sound effect, do their best
"Strange move", and also have their own special understanding of the recording position, recording method, and tuning method. 3. DIY or playing recording equipment, making your own special recording equipment. I used to
I have seen an 8-channel 4CH portable mixer made by Japanese audiophiles in Japan's "Wireless and Experiment" magazine. Its design and production level are no less than any professional tuning today.
Sound console. 4. The recording montage is the main means by which audiophiles will eventually produce their works, as well as their expression of human-natural feelings and the concentrated expression of artistic ideals. some
Adding natural sound to music, some connecting music fragments, some pursuing the "colorization" of sound, some even compiling works with natural sounds, etc.
Not surprising. For example, some people use more than 100 recordings of stormy waves to create "sound and picture" works, and so on. 5. Use the recording as an expression of one's own state
Appreciate and communicate with others, collect the works of other recording enthusiasts, burn the good recordings to the disc, conduct comparative research on the expression methods of recording, and cultivate your own skills in recording works
Appreciation ability. 6. Writing experience and articles. Especially the recording experience and experience of some scenes blended, leaving a valuable wealth for the development of recording level.
Recording enthusiasts are a very high class in the fever world, whether in terms of overall level or 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 such as MD and computer applications, the quality of audio equipment has been continuously improved, and people's income has increased.
The increased leisure time and improved traffic conditions have prepared conditions for the emergence of Chinese recording enthusiasts. Although we have not yet participated in the "recording concert", but
Natural recordings, recording montages, etc. are still promising. how about it! Would you like to try the fun of recording enthusiasts?
Home Audio Engineering
It mainly includes three aspects of design and decoration of listening room, audio equipment configuration and sound calibration technology
The listening room is the working environment of audio equipment, and also the key link of how to achieve the sound effect. Some audiophiles even think that its quality is related to whether the sound can be correctly restored.
The foundation is more important than the effect 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 balanced sound field. A properly treated family listening room should have a good performance on the frequency response of the sound, sound field reduction, and sound pressure balance, so that people have a live
Feeling, unknowingly living in the screw room. Compared with the concert hall, the living environment is much smaller in size and diverse in shape. There is no good architectural acoustic design, and the standing waves are distributed in the audible
Threshold, easy to be disturbed by the outdoor environment, and the decoration must meet the aesthetic requirements of the home, etc. The processing conditions are harsh, and many processing technologies used in hall audio cannot be simply applied, so
This has created the conditions for enthusiasts to practice architectural acoustics. Although there are not many opportunities for a person to decorate the listening room, you can start from the living room and the warehouse gradually.
Summarize and exchange some experiences in a practical way, learn more about some principles, and when the conditions are ripe, then proceed to design and decorate a special listening room.
The prosperity of the audio market, magazines and exhibitions has brought great convenience for audiophiles to access excellent audio equipment. Many audiophiles have brands for equipment in Europe, America, Japan and other countries.
The performance is like a few treasures. Knowing the sound effects and music performance produced by various equipments can compare the subtle differences. The configuration of audio equipment is already a fever in China today.
Friends have discussed the "hot topic" most, but it is not something anyone can do to configure the equipment well. Use different equipment to configure a good musical sense
The system is a highly skillful technology. It not only comes from being 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 device
The material matching process is not good, even for those high-end goods, when working together, the effect is often depressing; and many of the equipment that everyone seems to be flat, after appropriate
Match, you can still make a good sound, depending on whether you know the goods. Of course, to do a good job in equipment configuration, we must also consider "silver two", only in line with our own economic conditions
In the case of weighing, it is most reasonable to choose a satisfactory configuration. So, how to achieve this goal? Appreciate the effect of different equipment configurations by appraisal
Accomplishment and continuous accumulation of experience are the only way. Those who hear stories, build cars behind closed doors, and blindly pursue famous brands will find it difficult to succeed.
In home audio engineering, tuning is a seemingly easy and difficult process. You must first establish a sound calibration standard according to your purpose, so that
You can objectively evaluate the sound system's sound effects, starting with equipment adjustment and improving the acoustic characteristics of the listening environment, repeatedly patiently adjusting, summing up experience, and improving control
The equipment and the ability to overcome environmental defects gradually approach your ideal goal and create the sound effect you expect. There is a lot of knowledge you can learn in school tuning, speakers and other equipment
The position is very knowledgeable, the way to overcome the listening environment habit should also be constantly summarized in the adjustment, and even help your listening ability to improve. In short, if you pursue Hi-Fi
Perfect, school tuning will always accompany you along the path of fever.
With the development of audio technology, electronic technology and digital technology, the equipment we use today is designed, manufactured and developed following Hi-Fi's ideas. So fever equipment
The pursuit of Hi-Fi is the only standard and its soul, even for the production of sound control equipment, and it must be functionalized on the premise of ensuring Hi-Fi. today
, The frequency response of the amplifier can reach 100kHz at the high end (the index of the low-noise broadband amplifier has reached DC-2MHz), the total distortion reaches less than 0.1%, linear, transient, signal
Indicators such as noise ratio are close to the overall requirements of Hi-Fi, and are developing in the direction of personalization under the influence of the idea of ​​Hi-End; the signal conversion of A / D and D / A can be almost achieved technically
Arbitrary precision; 32CH multi-channel digital recording basically realizes the control of the full sound field information and the recording of the original sound; the ultra-massive optical information storage technology can achieve more precise sound signals
Lossless storage and extraction of interest; the development of sound control technology is more and more colorful, using DSP and other technologies, you can change the strength, phase, harmonic component, frequency of the sound signal according to needs
Rate response, transient performance, etc., provide great convenience for processing sound effects; through the cooperation of architectural acoustic technology and multi-channel playback technology, the sound field in the restricted room is restored
There is no longer a problem that is difficult to solve. It is no exaggeration to say that using existing technology has been able to recreate the original sound according to their own needs (such as some DJs)
The production of sound effects, some audiophiles' personalized matching and adjustment of the sound system), thus promoting the development of sound in the direction of art. Although the current technical level still needs
Perfect, there are still speakers, etc., which have developed slowly so far, and have not solved good problems.
Similar to photography, sound reproduction of sound is achieved in a passive way, which is more restrictive to artistic creation. Moreover, due to economic and other conditions, most domestic
The equipment owned by several audiophiles is very limited (almost all have only one set of equipment), and it is rarely possible to match different equipment in listening appreciation, so the scope of aesthetic realization is narrow, so they
The main concern is only the signal conversion technology, amplification technology and other issues to achieve sound reproduction, from a purely technical point of view to understand the sound. Especially by some traditional views of Hi-Fi
Due to the influence of thought, many audiophiles now do not think that sound can be used as a means of artistic creation, but rather as a tool to reproduce sound. It should be said that this situation
Compared with foreign countries, it is still in a relatively preliminary stage in fully understanding the technical nature of audio.
People who insist on "sound is the uniqueness of technology" believe that only when the sound is the only technology can the purity of Hi-Fi concept be guaranteed. However, this idea has been the ideal master from the beginning
Righteous! As long as the technology remains intact in the presence of non-linearities in the sound system, it cannot be achieved. Therefore, this view was severely challenged. First, electricity
There is no pure linear amplifier in theory, and the audio circuit is not the mainstream of the development of electronic technology. It is difficult to have a big breakthrough; second, since the idea of ​​Hi-End
The development of audio systems has been personalized to meet the realization of the aesthetic concept of people using audio; third, as society becomes more secular and commercialized, people
The use of sound for sound appreciation has also raised diverse requirements. If this situation continues, Hi-Fi's idea of ​​"true" as the only evaluation standard for audio will be disintegrated
. This is also the case, although the pursuit of true audio reproduction will continue, but more people will turn their eyes to satisfy the psychological experience of listening to the sound, making the sound of the sound
Sound reproduction is more artistic and more in line with the goals of their own aesthetic realization, and the utility and efficiency of audio technology are brought to the extreme, eventually exceeding the use of simple tools.
From a technical point of view, does the restoration of sound by sound only reflect the original nature of sound? In fact, the sound also includes its own performance on the sound, the so-called "
"British sound", "American sound" ...... It is precisely created using this nature, and no one thinks it is not in line with Hi-Fi, but there is only one real voice. Therefore,
Everyone has compromised on the sound of "only true" and "beautiful". There is only the problem of psychological acceptance or non-acceptance. And many speakers made in Japan, some for monitoring
The sound is very "true", but everyone doesn't like it. They think that there is a lack of cultural atmosphere, especially the Japanese sound is said to have no "music taste" and can't be heard at all. In terms of technology,
I believe that it is not difficult for Japanese people to make audio 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 nationalize, taking into account the factors introduced to the world, it must also contain European and American elements. Imagine if the Japanese penetrated their aesthetic concepts into the sound manufacturing, like this
Do you want to sell your stereo all over the world! Then take the road of "truth", at least this is a complete manifestation of Hi-Fi, but it is difficult to do in low-end products, and it caused
Condemned everyone. Let's talk about "Chinese Voice", although it also makes people dream, from the market, are manufacturers willing to do it? Enthusiasts are not necessarily British
, It's American.
For audiophiles, using existing equipment to match machines is now the same technology as DIY. This is because 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 enthusiasts abroad, they often have more than one set of equipment, so they can
The expression and selection of sound can be achieved through various combinations of equipment, and the appreciation target can be determined according to different sound characteristics, so that the image and meaning of the sound can be fully expressed according to their own ideals.
, In line with their own aesthetic needs. There are even some people who have given up their listening attitude based on the principle of "truth", believing that: appreciation must please me and should be what I need
. Introduce some of the sound control equipment into the listening and appreciation of the sound, and use the methods of changing the timbre, frequency response, sound field, time, etc. of the sound to achieve the purpose of appreciation.
Nevertheless, in order to ensure appreciation of the original sound, they still left a place for "true". This reminds me of why Spanish surrealist painters
Dali wants to change Mona Lisa to round eyes in the copy of "Mona Lisa", and add a mustache upward. This is actually an expression of using perfection to express oneself
. This may be unacceptable for Chinese people who have long been accustomed to figurative appreciation, as reflected in the appreciation of audio.
In addition, the development of computer technology will also create a new technical approach to the sound expression of audio, thereby enriching the aesthetics of audio.
