Playing APE format music is the best sound quality, APE format belongs to a lossless format, and MP3 comparison, from the file size, to 4 minutes long song for example, APE file is about 26MB, due to the MP3 through the compression, so only about 5MB. So MP3 is a lossy music file, and MP3 is only easy and collectible because of the small file size. When you listen to the same song in both formats, the sound quality of APE is much richer.
Lossless music formats such as FLAC, WAV, DTS and so on, but the car machine is not necessarily readable, especially DTS, most of the car machine can not be read and interpreted, and DTS music sound quality is more rich.

Mp3 is a kind of player that can play music files, which mainly consists of memory (memory card), display (LCD display), central processor [MCU (microcontroller) or decoding DSP (digital signal processor)], etc.
Mp3 is a kind of player that can play music files.
Saehan launched the world's first MP3 player, the MPMan F10, in 1998.
The MP3 player is in fact a functionally specific mini-computer. In the MP3 player small body, with MP3 player memory (memory card), MP3 player display (LCD display), MP3 player central processor [MCU (microcontroller) or MP3 player decoding DSP (digital signal processor) and so on. Microprocessor is the player's "brain", used to accept the user's choice of playback control, and the current playback of the song information is displayed on the LCD display, and then send instructions to the data signal processing chip, so that it accurately process the audio signal. The digital signal processor first decompresses the MP3 file with decompression algorithm, then converts the digital information into waveform information with digital-to-analog converter, and then the amplifier amplifies the signal and sends it to the audio port, and finally we can hear the melodious music through the headphones connected to the audio port. At the same time, we can use its own cable (USB) to connect with the computer, through the network to import their favorite audio files into the MP3, not only to listen to music, but also to carry out the necessary English listening training. In short, it is the crystallization of the wisdom of this information-based world
The first MP3
The birth of the world's first MP3, in fact, there is a small story, the story traces back to a day in March 1997, South Korea's Samsung Corporation, a departmental manager Moon (the Korean spelling of the last name "Moon"), returned to Seoul from a business trip in the United States, Mr. Moon. Mr. Moon ("Moon" in Korean), a division manager at Samsung in South Korea, was on a plane back to Seoul from a business trip to the U.S., and was reading a report on his laptop computer sent to him by a colleague. It is a presentation synthesized with images, text and MP3 music. When Moon finished reading and took off his headphones, he noticed that the traveler next to him was listening to an MD. Moon was inspired: wouldn't it be the best music on-the-go if the MP3 music files on his computer could also be taken out directly and played on a separate player? When he returned to Korea, he presented the idea to the president at the time. Unfortunately, Samsung was in the midst of organizational restructuring at the time and had no time for Moon's development proposal. Half a year later, the Asian financial crisis hit Samsung hard and Mr. Moon was forced to retire early. After leaving Samsung's head office, Mr. Moon joined Samsung's subsidiary Saehan as president, and turned his ideas into reality at Saehan, where he launched the world's first MP3 player, the MPMan F10, in 1998.
