The MPEG compression format is a set of standards for images and sounds formulated by the Motion Picture Experts Group.<\/p>\n<p>MP3 is an audio format designed to compress sound signals. Signal compression format standard. The sampling frequency of the CD is 44.1MHz, 16bit, and the data volume is 1.4Mbps, while the corresponding MP3 data volume is only 112kbps or 128kbps, which is 1\/12 of the original data volume.<\/p>\n<p>That is to say, there is a very important variation in the bitrate between a CD and an mp3. With a ratio of 1\/12, which is more or less the ratio between its size. However, as is well known, hate does not perceive that difference as long as the mp3 uses a bitrate of 128 kbps or higher.<\/p>\n<p>A traditional CD can now store 10 times or more the capacity of music, but in the human ear, the effect of music is no different.<\/p>\n<p>The working principle of MP3 Walkman is really very simple. It uses the control chip (CPU) to control the decoder chip and LCD screen, and the decoder chip decodes the MP3 file or WMA format file in the built-in flash memory or the external flash memory card. Then through the digital to analog conversion, and finally the output from the headphones.<br \/>\nMP3 players use the digital signal processor DSP (Digital Signal Processor) to complete the task of streaming processing and decoding of MP3 files. DSP is in charge of Walkman data transmission, device interface control, file decoding and playback, and other activities. The DSP can complete a variety of processing tasks in a very short time and this process consumes very little power (this is also a distinguishing feature of its suitability for portable players).<br \/>\nFirst, extract the MP3 song file from memory and read the signal in memory \u2192 decode the signal in the decoding chip \u2192 convert the decoded digital signal into an analog signal through the digital to analog converter \u2192 and then amplify the converted analog audio signal \u2192 After low-pass filtering, it goes to the headphone output and the output is the music we listen to.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How does an MP3 player work?
