How do MP3 technology players work?

MP3 technology; Millions of people have enjoyed music recordings since 1877, when Thomas Edison invented the gramophone. Then came the radio, records, tapes and CDs. But today’s digital audio players are a breakthrough in music technology.

 

Until recently, listening to music recordings involved moving the media mechanically through an interface to receive an analog signal called a waveform. This vibration signal was amplified and sent to the speakers where we heard it as sound. Digitization converts the waveform to a WAV file. This is a big improvement, but the archive is very large and a CD disc is limited to about 80 minutes of music.

So what is an iPod and how does it work?

 

The Apple iPod is the famous MP3 player. now question raised that  “How do iPods work?”

The software converts the music into a small digital file, usually WAV to MP3, using a codec such as MP3 or WMA. The codec compresses the file and removes sounds inaudible to the human ear. The digital file is stored in the flash memory or the micro-drive of the MP3 player. Because the file is so small, a player the size of a deck of cards can contain thousands of numbers.

 

The MP3 player performs various functions for playback. The built-in software reads the file, decompresses the encoding, converts it back to analog, amplifies the signal and sends it to the headphones. And voila, we have crystal-clear sound without the annoying crackles, thuds and hisses that occur mainly on records and tapes.

 

How we make mp3 (types of players, functions and features)

Even with a seemingly endless stream of new products, there are basically three types of audio devices that work well for duplicating audio CDs on a personal portable player.

 

Flash Players – The lowest, minimum expensive and most consistent. Using solid-state memory with built-in software, they have no moving parts, so battery life is longer and skipping is eliminated. They have limited memory, but can still hold dozens of numbers.

Micro-Drive Players: The small hard drives in these MP3 players have up to 60 GB of memory and can hold thousands of songs. Some also store and display photos. Anti-skip technology helps, but shock or vibration can still cause skipping. They generally have more functions and features than flash players.

MP3 CD Players –

The next generation of portable CD players. Using formats such as MP3, WMA and ATRAC, they play (some also record) CDs with 10 to 45 hours of music per disc. Play standard and / or 3 “Minidisc CDs. Standard CD format units cost less than most MP3 players. The prices of Minidisc players are higher, but contain the most music and are about the lowest price. Same format as an MP3 player with Microdrive Most play both pre-recorded and CD-R / RW discs. Features are similar to other players.
