When they first came into the market, MP3 players were very rudimentary gadgets. That was mostly at the turn of turn of the 21st century, and our memories of the first MP3-players are still quite vivid in our minds. The only file format they could support was the mp3juice format, in keeping with their name. They were mostly audio gadgets, to say that the only output you could typically expect from them was sound either through a speaker, or more commonly through earphones.
In a period of less than ten years, MP3-players have evolved greatly. Modern MP3 players are a far cry from the rudimentary gadgets of the old, in terms of features.One of the top features in the modern MP3-players is multi-file format support. As mentioned earlier, the best you could expect from the early MP3 player was support for the MP3 format – after all, weren’t you looking for a ‘MP3 players,’ tended to be the question.
The array of file formats supported by modern MP3 players, however, is truly amazing – from the MP3 format itself, of course, to Microsoft’s .Wav format, to the MIDI and even truly ‘amazing’ file formats, like .FLAC for codecs. Indeed, the modern MP3-player plays pretty much everything presented to it in a digitized format.
The second top feature to find in the modern MP3-players is USB functionality – which effectively makes them compatible with all other modern digital gadgets. If your memory serves you well, you will recall that the early MP3-players used to be more or less ‘stand alone devices’ so that the only way you could load music into them was, for instance, by buying those so-called ‘MP3s.
Thanks to USB functionality, however, there is a very great variety of places from which you can get music for the modern MP3 players – from the Internet, to other people’s MP3-players and even from some radio receiver sets. Some MP3-players have ports through which they can take in USB devices, such as flash disks and memory cards, whereas some even have features which allow them to function as flash disks themselves .
The third top feature that you will find in modern MP3 players is video capability – which has effectively transformed them from just being audio gadgets, into being audio-visual gadgets. In most modern MP3 players, you not only get to listen to your music but even see the music videos behind it, on the MP3 player screens. The screens on these modern MP3 players can be anything from LCD-based to TFT-based, to make way for quality viewing.
The fourth top feature that you will find in modern MP3 players is a lot of storage space. Today, we have MP3 coming with as much as 20 GB of storage space – more space than some older computers could ever offer even with extensions. This storage space effectively converts the MP3 from just the file playing devices there were initially, to being file storage devices as well.
The memory types are internal flash memory, compact flash cards, smart-media cards, memory-stick, and internal-micro-drive. All are solid-state memory with the exception of internal-micro-drive. Without moving parts the advantage is more reliability. Moreover, music does not skip. The MP3 contains minuscule hard-disk drives having the capacity to store 150 times more than flash-memory technology.
The brain of the player is the microprocessor.
Through playback controls it monitors the input and shows information about the current song while sending relevant directions to the DSP chip.Apart from storing music MP3 player plays music by drawing out the songs from memory and allows for amplification to enable the user to hear.
