MP3 player
A Korean man was reading a file with background music on the plane and suddenly had a sudden idea: Can the music playback function be independent from the computer? Is it possible to store and play music with a small and portable device? Inspiration became the most direct driving force. After many twists and turns, this person finally developed the world's first MP3 player in 1998...
Massive storage, compact and portable, and almost all songs are free. For a time, the small MP3 player completely replaced personal entertainment devices such as Walkmans and portable CDs, becoming synonymous with the "fashion" and "popularity" of mass digital products; and with its rapid popularity in the short term, the emerging MP3 industry quickly It has become the most eye-catching scenery in the huge IT industry.
MP3 player----the new darling of the E era
1.MP3 player----the most compact and portable player
In MP3 Before its birth, PC users used the WAV format to record, download and play high-quality sound files; however, WAV files are relatively large. It takes 10MB of space to record one minute of CD-quality WAV songs, and a 10-song CD The CD is over 200MB! This puts forward the requirements for these data compressions. MP3 is a file compression technology (MPEG is the abbreviation of Motion Picture Experts Group, mainly used in sound and image compression processing). Its full English name is: MPEG-1 Layer 3. The so-called "MPEG" refers to the "Movie Picture Experts Group", which is a working group established by the ISO (International Standardization Organization) in 1988 to formulate standards for compression and coding of moving images. . The MPEG-1 standard (ISO/IEC 11172), MPEG-2 standard (ISO/IEC 13813), MPEG-3 and MPEG-4 standards are all developed through this group. The MPEG compression format is divided into MPEG Audio Layer-1, Layer-2 and Layer-33 layers.
The compression ratio of MP3 is far greater than that of MD. It completely cuts out the high-pitched music above 16KHz that is difficult for the human ear to hear. Therefore, MP3 can use it without greatly reducing the sound quality. The compression ratio of 1:10 or even 1:12 greatly reduces the file size, which is beneficial to the storage of music files. It can be seen that it uses lossy compression that is completely different from MD. Therefore, from the algorithm point of view, MP3 is not the opponent of MD. But as the Internet boomed in the mid-to-late 1990s, MP3 began to become a popular audio compression format on the Internet.
In 1998, South Korea's SEAHAN company launched the world's first MP3 player - MP MAN MPF-10. The Walkman entered the E era. Following Japan's Sony Corporation's strategy in Walkman and Discman, Sehan calls this latest product MPman. The implication is that they hope that their products can become synonymous with portable MP3 player products. Although Saehan has rarely launched new models now, this F-10, as the originator, has led us into the world of online music E. Although many people had a wait-and-see attitude towards Mpman at that time, just like Sony president Shao Morita designed the Walkman on a whim more than 20 years ago, many people did not understand this kind of "brick" that could only play music. Today, Walkman can be seen everywhere. This is another milestone product, so with the release of DIAMOND's MP3 "RIO" in the same year, it showed that mature MP3 players officially entered the market. This is why many people think that the first MP3 was DIAMOND. . It has been 5 to 6 years since MP3 was born. Now it is leading a new music craze and developing in full swing.
2. Memory Stick Walkman and NETWORK WALKMAN---the king’s masterpiece (whether the king’s masterpiece will be the king of sales, everyone naturally knows)
After all, it is electronic A big player in the consumer market, in 1999, SONY released the MS7, a memory stick player using the ATRAC3 format. The compression rate of ATRAC, a sound compression technology, is approximately twice that of the ATRAC sound compression technology used in MD. The size of a song in ATRAC3 format is equivalent to MP3, but the sound quality is much better than MP3. Most of them, Yan Lihuang secretly knew Xingjiu's pen coat, alliance concubines, silkworms, captured, dazzled, sent ⒉ ring shallow? Under the aggressive situation of the P3, the Sony This veteran who has grasped the market has launched ATRAC3 encoding, and the market name is MDLP--MiniDisc Long Play.
This encoding technology increases the compression rate based on the original ATRAC encoding, greatly reducing the ATRAC format files at the expense of a certain sound quality. An MD disc that could originally store 74 minutes, depending on the compression rate, Now it can hold double or even quadruple the amount of music. Consumers can enjoy music with less trouble and money. MDLP's GROUP "Track Grouping" function can combine the music tracks that the user wants to listen to into a group or customize more groups. In other words, the recorded MD tracks can be classified and managed in categories. , which is equivalent to the folder management function in MP3, allowing users to play the required music track groups at any time. This is very simple and fast for a disc with quite a lot of tracks.

The 5GB belly can hold 70 hours of compression at a 160kbps compression rate. MP3 music, if each song is 4 minutes long, it can hold 1,000 songs! This kind of capacity is unmatched by other Walkmans. Unfortunately, it can only be connected to computers using MAC systems and does not support PCs using Windows operating systems.
