MP3 Music Technology
Earlier form of music players requires moving parts to read embedded data on a tape or CD while MP3 players use fixed status memory. An MP3 player is more of a data storage device with a built-in software application that allows users to transfer MP3 files to the player. MP3 players contain some features to copy and then organize music from CDs or Web sites and create a custom list of songs in the order you want them to hear. Such a list of songs is called a playlist.
The MP3 player is the combination of various technologies and its components are not only revolutionary, but also seem to be a good consumer product. If you also want to save music, the user can hear the songs being played. For this player, the player draws the first song from its memory, then decompresses the MP3 encoding, downloads the decompressed by a digital to analog converter, and amplifies the analog signal so that the song can be heard.
There are different things or components, but it can vary as the basic parts of a typical MP3 player. This includes data port, memory, microprocessor, digital signal processor, display, playback control, audio port, amplifier and power supply.
The player is plugged into the USB port of your computer or a parallel port to transfer data. USB-based players use data faster than using the parallel port. Memory types include internal flash memory, compact flash cards, smart media cards, memory stick and internal micro-drive.
Besides the last one, all of the above-mentioned players are of standalone memory and the advantage of solid state memory is that there are no moving parts that mean better reliability and music without any ships. MP3 players also contain small hard drive drivers capable of storing 10 to 150 times more than flash memory devices.
The microprocessor is the brain of any player and monitors user input through the game controls and displays information about the current song on the LCD panel and then sends directions to the DSP chip that explains how the audio is being processed. The DSP extracts the song data from memory and applies special effects and currents to the amplifier. The DSP runs a decompression algorithm that compresses MP3 files and then resets the bytes in sound waves.
The amplifier also increases the signal strength and then sends it to the audio port that allows you to connect the headphones. Most MP3 players are powered by the battery.
