Do you know, how do MP3 players work? These little portable music devices seem to bring songs to life magically. In reality, the only magic at work is the magic of technology. Let's take a look at how an MP3 player brings music to your ears.
The MP3 File Type
An MP3 player gets its name from the type of file it supports. MP3s are compressed audio files that are stored digitally, with near CD level clarity. But, because the files are compressed, MP3 files take up far less space. For example, 1 gigabyte of memory can hold about 20 CDs worth of audio. The trade off for the compression is a loss of sound quality, but it's a trade most are willing to make for the convenience of having so many songs at their disposal.
MP3 Players Equal Mini-Computers
MP3 players work like computers. In fact, they are mini-computers. They contain small hard drives that hold your audio files. This is referred to as solid-state memory since there are no moving parts, as opposed to CD players, which need to spin the CD in order to read the data off the disc. This makes MP3 players much less susceptible to skipping.
They also contain a microprocessor that delegates the control functions: play, fast forward, rewind or pause. In addition, they also have a component known as DPS, or Digital Signal Processor, which is responsible for decoding the MP3 data and converting it into music. MP3 players are powered by batteries, whether they be internal rechargeable batteries or replaceable AAs.
Popular MP3 Players
The iPod is arguably the most popular MP3 device; however, plenty of other brands are on the market, such as the Microsoft MP3 player, Zune. MP3 player accessories usually include a pair of headphones and a strap to secure the device to your body when working out. Even though MP3 players don't have moving parts, you still want to protect it.
