MP3 Digital Music Technology
Earlier form of music players needed moving parts to read enclosed info on a tape or CD while MP3 players use solid state memory.
An MP3 player is more of an info storage device with an inserted software application that allows users to transfer MP3 files to that player. MP3 players include some resources to repeat music from CD or web sites and then get them in order and create custom list of songs in the order you need to hear them. Such list of songs is known as a play list. The MP3 player is the fusion of diverse technologies and its components aren't only revolutionary but also turn out to be a great consumer good. Should you want to store music as well permit the user to hear the tracks played and for this the player first pulls the track from its memory, then decompresses the MP3 encoding, runs the decompressed bytes thru a digital to analog converter and amplifies the analog signal permitting the track to get heard. There are several stuffs or elements but these could change as the basic parts of a normal 8GB MP3 player. The player is wired into the USB port of your PC or a parallel port to transfer info. Memory types include internal flash memory, compact flash cards, smart media cards, memory stick and internal micro drive. Except for the last one, all of the above discussed players are of solid state memory and the benefit of solid state memory is that there are no moving parts that mean better trustworthiness and music without any skips. The microprocessor is the brain of any player and monitors user input thru the playback controls and displays info about the present song on the LCD panel and then sends directions to the DSP chip that informs precisely the way the audio is processed.
The DSP pulls the track info from memory and apply any CGI effects and streams to the amplifier.
The amplifier also boosts the power of the signal and then sends it to the audio port whereby you can attach the pair of headphones. The majority of the MP3 players draw power from battery.
