What is the difference between vinyl music and CD music?
To answer this question, we must first understand the development history of these music and their special characteristics; why do we still play old things in the digital age? Mainly because the ethereal and live feeling are the characteristics of today’s CDs Irreplaceable. If you have listened to LP, you will not be able to stand the sharp and rough digital sound of today's CDs. Modern CDs have developed numerous circuits and recording modes in order to reduce digital sound as much as possible, but they still cannot compete with LP.
The equipment that plays LP is called a turn table (phonograph). It generally does not have a power amplifier, but is just the output of the pre-stage. The pickup mode includes moving magnet, moving coil and moving iron cartridges, and The linear tracking cartridge and tone arm of the moving iron are the best. Regardless of various technical parameters, among the various music recording materials developed so far: records, tapes, and CDs, the sound quality of LP is closest to the original sound, which is the state pursued by music lovers. Most of the works of many heavyweight performers, conductors, big bands and singers were released on vinyl records for the first time. SP has a long life as long as it is stored properly. Nowadays, vinyl records are rare items, especially famous ones from decades ago, which are even more valuable.
Vinyl records were the dominant music format in the 20th century. Because vinyl feels more fidelity to the ears and is cheaper, it perfectly covers people of all ages who pursue the ultimate in music. Although vinyl is still used by DJs and radio stations, it has been relegated to garage status.
Vinyl, also known as LP, long play, is a compact record made of stereo black celluloid.
Chinese name: vinyl record
Foreign name: vinyl
Commonly known as: Bakelite record
Inventor: Radio Corporation of America (RCA)
Beginning in 1948, 33 and 1/3 (33 1/3) records were released. After several years of development, the recording time on one side was nearly 22 minutes, which was longer than before. There are many, so it is called LongPlaying. Compared with the current state of technology, there is the so-called "SP", which is Standard-Playing, which is 78 revolutions per minute. Most of the records currently in use are 33 rpm, so vinyl records are directly called "LP".
The common specifications are 10-inch LP, which has a short recording time and can generally only record one song. 12-inch LP has a longer recording time, up to 5 minutes, and is also a standard specification for stereo LP.
Vinyl records, as a carrier of sound and music, occupied almost the entire 20th century until the birth of the CD in 1984. When my country entered the CD era in 1992, a large number of vinyl production lines were eliminated, and the price of vinyl records dropped from about 30 yuan to about 15 yuan. However, due to the preferences of collectors, the price of vinyl records gradually recovered starting in 1994, and by 1996 it exceeded 100 yuan.
CD replaces LP
CD uses binary digital recording method of 0 and 1, which determines that the recorded content is essentially different from the master tape of analog recording. Compared with the master tape, any recording is bound to lose information. Just like a model and her portrait, no matter how realistic the painting is, it is just a likeness and not the same thing. Vinyl basically uses an analog recording form, and the content recorded on the analog recording master tape is consistent. The difference lies in the loss of the master tape and equipment transmission during the transcription process. Just like a person taking the same pose at different times, it is a true reproduction. The replacement of vinyl by CD lies in the rules of business and social transactions. The cost required to produce a CD is estimated to be only a few cents of plastic, and the transportation volume is small. It can be sold for tens of yuan, and the CD will not jump. The profit is astonishing, and the acceptability and affordability of consumers are both. is obvious.
The mass production of vinyl copper molds already costs a few yuan per disc, not counting the cost of polyethylene raw materials. Transportation is heavy and takes up space, and it is not easy to store and easily lose jumpers. It also sells for dozens. If it is RMB 10,000, I am afraid that the profit will not be large and consumers will not be willing to buy it. In contrast, vinyl will inevitably be replaced by CD in the mainstream market.
Getting started
Playing LP requires patience, because listening to LP requires a lot of preparation and is very troublesome. LP will force you to slow down the pace of your life and listen to each piece one by one. It is not as convenient as CD selection, so you will listen to the music carefully. The pleasure of playing LP vinyl records is like knowing whether the water is hot or cold when you drink it. You must know the basic actions and necessary equipment before listening. You should also pay attention to record dust removal, cleaning stylus and other maintenance procedures that require patience. When buying second-hand information, be sure to check for scratches, especially if it contains several LPs. You should also read them one by one. Since you can listen to them on a trial basis, if you have enough time, it is best to listen carefully first. If you are interested, it is better to go to some second-hand LP stores that specialize in selling high-quality classics, buy a few vinyl records to take home, and taste the nostalgic feelings brought by the thickness and elegance.
Vinyl and CD are two different ways of recording sound. The vinyl turntable was developed based on the Edison phonograph.
Sound is a sound wave formed by the vibration of a sound source pushing air. In order to be able to feel sound information, nature has equipped humans and animals with hearing artifacts - ears. Air vibrations are transmitted to the eardrum, and then the ears convert this vibration into bioelectric signals and transmit them to the brain, so we hear sounds. In this sense vibration is the essence of sound.
The principle of a vinyl disc can be described as follows: it is made by burning grooves on a rotating vinyl disc with a steel needle that vibrates with sound. When playing sound, use a steel needle to draw across the groove at the same speed. The steel needle will vibrate according to the rules during recording and drive the diaphragm to produce sound through the horn. Modern record players only convert the vibration of the stylus into audio current, which is then amplified and modified by the circuit to make the volume louder and the sound quality better.
It can be seen that whether it is an old-fashioned gramophone or a record player, mechanical vibration is used to restore the sound. It can be said that the vinyl record disc records the sound itself, so the sound playback effect has its own uniqueness. This is also The reason why people pursue vinyl. In fact, not only vinyl, but plastics can also be made into turntables, which was all the rage in the 1970s and 1980s.
But vinyl records also have their inherent shortcomings. Since it is a mechanical vibration, it is limited by factors such as the weight and inertia of the stylus and the friction coefficient between the stylus and the vinyl. It is impossible to completely match the waveform and amplitude of the original sound, especially the large amplitude of the bass and the high frequency of the treble. There are obvious shortcomings, which are especially serious in old phonographs without amplification circuits. Modern vinyl record players use circuitry to compensate for these deficiencies, and while compensating, they also add distortion to the circuitry. But overall the sound quality has improved a lot.
In addition, vinyl turntables also have a fatal shortcoming: mechanical wear. In particular, in order to obtain sufficient volume, old-fashioned gramophones have large needle pressures and use steel needles. They need to be lubricated with record oil when placing a disk, and the needles need to be replaced every time a disk is placed. It is really not something that ordinary people can afford. Today's vinyl record players have reduced needle pressure and use gem needles, but it is still impossible to solve the deterioration of sound quality caused by mechanical wear and short service life.
Look at the CD again. It is a high-tech product that integrates modern multi-disciplinary technologies. It does not directly record the sound like a vinyl record, but uses electroacoustic devices such as microphones to turn the sound into audio current, then samples it, and converts it into a digital signal through circuit encoding and burns it on the disc. Therefore, what is recorded on the disc is not sound, but digital signals of varying lengths similar to those sent by old-fashioned telegraph machines. From this point it can be seen that the sound of CD is not continuous. But it's like using several points to form a line, as long as the points are numerous and dense enough. It can be regarded as a continuous line, because too rapid changes are not perceptible to the human ear.
During playback, the digital signal on the disc is picked up by the laser head, and then decoded and restored to an analog signal. After amplification, the sound is played through headphones or speakers. The sound quality of a CD mainly depends on the density of samples. The higher the density, the closer it is to the original sound.
CD music is characterized by clean background and wide sound range. There is no mechanical wear during playback, there is no difference in sound quality between old discs and new discs, and they can be transmitted and copied without loss. However, the recording and playback process of CD requires encoding and decoding, so strictly speaking, CD plays cloned music as it is, not the original version. Although the sampling density is now high enough, people's listening experience still has a cold and hard feeling.
What vinyl records is the sound itself, which is closer to reality. So the listening experience is sometimes better. However, due to the limitations of the mechanical structure, the sound range and transient response are far inferior to those of CDs. And theoretically speaking, due to mechanical wear and tear, the sound quality will gradually deteriorate every time it is played.
It can be seen that vinyl and CD are two completely different recording methods, each with its own advantages. However, both recording methods inevitably have unique distortions. But now there is a kind of vinyl CD that puzzles me. If vinyl is used as the master disc, wouldn't it be superimposing two different distortions? If the original sound is used directly as the sound source, what does it have to do with vinyl?
My first impression of vinyl discs was from the Shanghai movies of the 1920s and 1930s. The black and white slightly scratched films showed a wealthy man and lady holding a beautiful glass wine glass or dancing. Or sitting in an elegant room, with pure sounds coming from a trumpet-shaped black record player behind you, including blues or the crooning of a popular female star.
Vinyl is transparent, clear, and open, with hidden flaws. What it conveys through your ears is a warm feeling that is very much like a real person breathing beside you. It is humane and not as cold as digital.
The 10 years from 1965 to 1975 were the golden age of classical music, and there has never been such a period since. All classical music masters, including mixers, recorded countless classic records during that period. The way records were recorded at that time could only be successful once. If a microphone was not placed properly or an instrument was not paired properly, it would have to be done all over again. There are now fewer mixers of such a high level in the world combined. More than 10. And coincidentally, the most important music carrier at that time was vinyl records, which fortunately preserved the best music. For example, Domingo, one of the three great tenors, can't compare with his singing skills now in the 1970s.
Universal CD
CD stands for Compact Laser Disc and is a general term used for all CD media formats. CD formats currently on the market include audio CD, CD-ROM, CD-ROM XA, photo CD, CD-I and video CD, etc. Among these various CD formats, perhaps the most familiar one is audio CD, which is a standard CD format for storing sound signal tracks such as music and songs. CD Digital Audio (CDDA) was introduced by Sony and Philip during the 1980s as a form of music distribution. Because of the huge success of audio CDs, today the use of this medium has expanded to include data storage for the purposes of data archiving and transfer. Compared with various traditional data storage media such as floppy disks and audio tapes, CDs are most suitable for storing large amounts of data, which may be any form or combination of computer files, audio signal data, photo image files, software applications and videos. data. Advantages of CDs include durability, convenience, and cost effectiveness.

What is the difference between vinyl records and vinyl CDs?
I want to know whether the effect of the original large vinyl record is more realistic or is it the same as a vinyl CD? Then I want to understand Which of the two has better sound quality? Can anyone with knowledge of the matter explain the advantages and disadvantages of the two in detail and make a comparison? Thank you! More detailed reward points will be posted

Hello everyone, I would like to share with you what I know about vinyl and CD.
Vinyl is generally called LP, long play, in foreign countries. It is a compact record made of stereo black celluloid. It was invented by an American radio company during World War II, and was later improved by the Germans and became popular in the world of audio production.
Vinyl is produced through sound-electrical signal-mechanical signal-disc texture, while CD is produced through digital sampling-recording of digital signals. Vinyl is recorded in an analog form, and the content recorded on the analog recording master tape is consistent. The difference lies in the loss of the master tape and equipment transmission during the transcription process. Just like a person taking the same pose at different times, it is a true reproduction.
CD uses a binary digital 01 recording method, and its recorded content is essentially different from the master tape of analog recording. Any recording is bound to have a missing amount of information compared to the master tape. Just like a real person and his portrait, no matter how superb the painting skills are and the painting is lifelike, it is just a portrait and not the same thing.
The CD digital audio signal CDDA was developed by Sony and Philip during the 1980s as a form of music distribution.
CD refers to the small laser disc, a term used for all CD media formats. CD formats include audio CD, CD-ROM, CD-ROM XA, photo CD, CD-I and video CD, etc. Among these various CD formats, the most familiar one is Audio CD, which is a standard CD format used to store sound signal tracks such as music and songs.
The so-called vinyl CDs in the world today are just laser disc bases with dark dye added to them. They are just ordinary digital audio CDs. There is no analog-recorded vinyl anymore.
This is a real vinyl record, played on a gramophone.
The following is a CD, played with a digital audio player
The above is my humble opinion. I am not an expert. I hope everyone will reply and correct me if I have any mistakes.
After seeing many people answering their differences based on their appearance, I will not elaborate further. I plan to elaborate on their working principles. The working principles of vinyl records and CDs are different. First, let me briefly describe their principles to you. Working Principle of Vinyl Records
Vinyl records are produced through sound-electrical signals-mechanical signals-disc textures. The mechanical energy loss in this process is particularly large. Any mechanical transmission will be affected by the environment, temperature, Gravity and other aspects of the impact. The vinyl master tape will definitely suffer the least loss. If you want to copy and burn it again, the loss will only become bigger and bigger. But usually everyone can only get the copy and burnt disc instead of the master tape. Working principle of CD
CD is produced through digital sampling and recording digital signals. There must be some loss during the sampling process, and the sampling rate determines the audio range, but the sampling rate of CD is very high. , high enough to exceed the hearing range of the human ear, so from this point of view the so-called "lossy" is meaningless, what is lost is the inaudible part. Apart from the loss in this process, there is no other loss in the sound quality of the entire CD system. Therefore, the sound quality of the copied recording disc and the master tape are exactly the same. Hearing experience
Vinyl will cause wear due to the increase in the number of uses, and under the influence of dust and pointers, the actual effect is often better than the sound quality of CDs. This leads to the listening experience of the two, with CDs being better than vinyl records.
The carriers and playback technologies used to record music are different. Vinyl records are made by engraving musical patterns on a phenolic plastic sheet. During playback, a metal probe is used to physically contact the vinyl record to read the sound signal. CD uses a (laser) method to densely burn sound signals onto polycarbonate (PC) film. During playback, the laser emitted by the laser head is used to read. What is the difference between vinyl music and CD music?
In theory, vinyl has better sound quality than CD.
