Excuse me, what is the format of general car MP3 music?

APE format music has the best sound quality. APE format belongs to lossless format. Compared with MP3, in terms of file size, for example, a song with a duration of 4 minutes is about 26MB. Because MP3 is compressed, it is only about 5MB. So MP3 is a lossy music file, and MP3 is only small and easy to collect. The same song in two formats sounds that the sound quality of APE is much richer.

Lossless music formats include FLAC, WAV, DTS and so on. But the car-mounted machines may not be able to understand it, especially DTS, most of which are hard to understand, and the sound quality of DTS music is richer.

This entry is compiled and applied by the scientific entry "Popular Science China"? Review.

Mp3 is a player that can play music files. It is mainly composed of memory (memory card), display (LCD screen) and central processing unit ([MCU] or decoding DSP (digital signal processor).

Saehan Company introduced the world's first MP3 player-MPMAN F10 in/998.

MP3 player is actually a small computer with specific functions. In the small body of MP3 player, there are MP3 player memory (memory card), MP3 player display (LCD display), MP3 player central processing unit ([MCU] or MP3 player decoding DSP (digital signal processor) and so on. Microprocessor is the "brain" of the player, which is used to accept the playback control selected by the user, display the currently played song information on the LCD screen, and then send instructions to the data signal processing chip to make it accurately process the audio signal. The digital signal processor firstly decompresses the MP3 file with the decompression algorithm, then converts the digital information into waveform information with the digital-to-analog converter, which is amplified by the amplifier and sent to the audio port. Finally, we can listen to beautiful music through headphones connected to the audio port. At the same time, you can use your own data cable (USB) to connect with the computer and import your favorite audio files into MP3 through the network, so that you can not only listen to music, but also conduct necessary English listening training. In short, it is the crystallization of the wisdom of this information world.

The first MP3 player

There is actually a short story about the birth of the first MP3 player in the world. The story dates back to one day in March. 1997. Mr Moon, a department manager of South Korea's Samsung Company, is on a business trip. On the plane back to Seoul, USA, he used his laptop to read a report sent to him by his colleagues. This is a display of images, words and MP3 music. When Moon took off her headphones after watching it and found that all the passengers nearby were listening to MD, Moon immediately had an idea: wouldn't it be the best music walkman if MP3 music files on the computer could also be directly taken out and played by an independent player? After returning to Korea, he brought this idea to the then president. Unfortunately, at that time, Samsung was in the process of organizational restructuring and had no time to take into account Moon's development proposal. Six months later, the Asian financial turmoil hit Samsung hard, and Moon Jae in was forced to retire early. After leaving Samsung's headquarters, Mr Moon joined Samsung's subsidiary, Shinhan (Han Shi), as the president, and turned his idea into reality in Shinhan. 1998, he introduced the world's first MP3 player-MPMAN F10.
