How to distinguish the sound quality of MP3? Those MP3 brands have good sound quality.

MP3 sound quality

Does MP3 sound quality have something to do with headphones? I want to buy an MP3 that can listen to songs. Is MP3 good or practical MP4?

1. Common name for portable MP3 player. a portable player
used to play music in MP3 format (now compatible with wma, wav and other formats). Portable MP3 players were originally developed by South Koreans Kwang Soo and Huang Dingxia (Moon & Hwang) was invented in 1997 and applied for related patents.
2. MP3 as music format
MPEG-1 Audio Layer 3, often called MP3, is today’s most popular lossy compression and digital audio encoding format. It is used to drastically reduce the amount of audio. data, while for most users the playback quality is not significantly degraded compared to the original uncompressed audio. It was invented and standardized in 1991 by a group of engineers at the Fraunhofer-Gesellschaft research organization in Erlangen, Germany.
General information
MP3 is a data compression format. It discards pulse code modulation (PCM) audio data that is not important to the human ear (similar to how JPEG is lossy image compression), resulting in a much smaller file size.
Various techniques are used in MP3, including psychoacoustics, to determine which parts of the audio can be discarded. MP3 audio can be compressed at different bit rates, providing a variety of trade-offs between data size and sound quality.

Four factors that determine the sound quality of MP3 Walkman

MP3 AUDIO QUALITY

The current mp3 market is full of flowers and the competition between the major manufacturers is splendid. In order to take the lead and gain the most market share, various manufacturers, especially those with strength, have their own unique tricks. In terms of appearance, mpio’s fl200 has won the award with its mini round cake design. unique pendant. The latest mp3 title, Truly’s mp379, also created the trend of big screen mp3, and Samsung also released its sports mp3 concept, which is absolutely amazing in the market.

Some small manufacturers have also adopted imitation methods, making all kinds of mp3 on the market like a sky full of stars, countless. Simple repeat, record and fm functions can also meet the needs of the market.

Line-in, features, e-book reading, gaming, and colorful backlights are slowly creeping into the new mp3 design. However, the author believes that no matter how cool it looks and how perfect its functions are, the mp3 is used to enjoy music in the final analysis. An mp3 without good sound quality is at least not a qualified mp3. If you are just looking for the appearance and function (actually, we rarely use some functions), and if you ignore the performance of sound quality, you will feel a bit like buying a scorpion. Currently, there are many types of mp3.

A decoder chip inherent in mp3

The decoder chip used by the Mp3 itself is the key to its sound quality. The sound quality displayed by high quality decoder chips is unmatched by those of the poorest. Friends who have listened to the famous iriver series of mp3s will know that its sound quality is very obvious, the bass is strong and powerful, the vocals are restored to truth, the high-frequency field is wide, and the boost is sufficient. , which is very pleasing to the ears. This series mp3 adopts Philips SAA7750, the most advanced decoder chip in the market, and its quality and performance are excellent. The major Korean manufacturer MPIPO (Dewei Technology) also uses this decoder chip. The reputation and market feedback of these two mp3 sound quality brands are very good, and they are highly praised by the industry and outside the industry.

It proves that mp3 sound quality is better than md’s ace gun. Due to the relatively high cost of the chip and the control chip, it is rarely used except for some brands. The cost is high, and the price is of course expensive. This is also the threshold that restricts many mp3 lovers from enjoying the beautiful sound quality.
The most widely used decoder chip on the market today is, of course, the well-known STMP3410 from Sigmatel. Whenever you disassemble your mp3, you will find that your mp3 uses STMP3410 decoder chip. The decoder chip is highly integrated and has concentrated functions. It is easy for manufacturers to develop or add new features such as letter display and electronic dictionary. All brands that cannot be called are used, the sound quality is quite satisfactory, the low frequency is a bit weak, the voices and musical instruments are not bad. Of course, the sound quality performance of mp3 using STMP3410 decoder chip is not the same and sometimes even very different. The reason lies in the internal circuit design of the mp3, the soldering process, the material of the circuit board, and the difference between various manufacturers, especially There is a big difference between the big manufacturers and some non-brand manufacturers. These are also the key factors that affect the work of the decoding chip and the sound quality output. Take two high-end machines that also use the STMP3410 chip and compare the unbranded machines to understand. Therefore, due to many factors within the mp3, the price of the mp3 that also uses the STMP3410 chip varies.

Is listening to music on vinyl really better?

Vinyl / MP3 theme seems to be all the rage. Some vinyl purists believe that there is no debate. “You understand that when you listen to a vinyl, it is better, cpocomprésséblabla […] blabla”, we all live this type of conversation with an individual with the red label “with (ne) base”.

 

MP3 vs WAV vs VINYL

The “micro-groove” vinyl record was released on June 18, 1948 during a press conference organized by Columbia Records to announce the end of 78 rpm. Format adopted by the general public since the mid-1950s, vinyl will remain the exclusive medium of music for almost 20 years.

The Compact Disc arrives in 1982 and offers quality music transcription based on a sample of 44,100 Hz. Sound is collected 44,100 times per second. This rate gives it an accuracy close to that of vinyl.

Vinyl vs mp3

MP3 was released in the mid-90s. Wanting to reduce the weight of songs and fit on our “smartphones”, it compresses the audio data. This results in loss and degraded sound, provided you listen carefully on a high-quality sound system. Finally, everything also depends on the compression rate mentioned in bitrate per second. Corresponds to a bit rate of binary information (or bits) per second: a bit rate of 320 Kilo-Bits-per second corresponds to approximately 320,000 bits transmitted per second. This is the reason that the less the sound is compressed, the more information the file has and, consequently, the bigger it will be. To listen more or less faithful to the sound, above 256 Kbps, you go alone. It is always possible to choose the so-called “lossless” formats like FLAC,

Sound can be defined as a wave, a signal that vibrates the membrane of the inner ear at a certain frequency. To clarify things, we must quickly analyze the concept of bandwidth, which is the range of reproducible audio frequencies for each medium. The higher the frequency, the higher the note; the lower the frequency, the lower the sound (hence the bass name for bass, little genius). Your broken headphones or your Funktions One are just trying to transcribe this signal.

The vinyl bandwidth is, in principle, unlimited. MP3 seeks to reproduce this signal as faithfully as possible. An excellent quality vinyl record can store sound information at frequencies up to around 50,000 Hz. In lossless mp3, the frequency range generally reaches around 23,000 Hz.

FUN FACT: The human ear can hear frequencies ranging from 16Hz to 20,000Hz. We cannot capture the entire frequency spectrum of a vinyl or MP3.

It is often said (too?) About vinyl that is distinguished from MP3 by its warm sound, by its “grain”. In fact, there is a noticeable difference between listening to an MP3 and a vinyl because the recording techniques are different, hence the famous “grain” of the vinyl, but it is reproducible without problems in numerical format

From a technical point of view, vinyl is no better than an MP3 in the correct format. Surely there are many more emotional considerations to help understand the new vinyl spring.
