MP3 Music Technology

Earlier form of music players required moving parts to read enclosed data on a tape or CD whereas MP3 players use solid state memory. An MP3 player is more of a data storage device with an embedded software application that enables users to transfer MP3 files to that player. MP3 players include some utilities to copy music from CD or websites and then organize them and create custom list of songs in the order you want to hear them. Such list of songs is called a "play list".

The MP3 player is the combination of various technologies and its components are not only revolutionary but also prove to be a great consumer product. If you wish to store music as well allow the user to hear the songs played and for this the player first pulls the song from its memory, then decompresses the MP3 encoding, runs the decompressed bytes through a digital to analog converter and amplifies the analog signal allowing the song to be heard.
Tip! You can easily download free mp3 song from different websites offering these services.

There are different stuffs or components but these could vary as the basic parts of a typical MP3 player. This includes data port, memory, microprocessor, digital signal processor, display, playback controls, audio port, amplifier and power supply.

The player is plugged into the port of your computer or a parallel port to transfer data. Port based players transfer data much faster than those using the parallel port. Memory types include internal flash memory, compact flash cards, smart media cards, memory stick and internal micro drive.
Tip! It is also used by many legal mp3 download sites.

Except the last one, all the above mentioned players are of solid state memory and the advantage of solid state memory is that there are no moving parts that mean better reliability and music without any skips. Mp3 players also contain tiny hard disk drives that could store 10 to 150times more than flash memory devices.

The microprocessor is the brain of any player and monitors user input through the playback controls and displays information about the current song on the LCD panel and then sends directions to the chip that informs exactly how the audio is processed. It pulls the song data from memory and apply any special effects and streams to the amplifier. It runs a decompression algorithm that compresses MP3 files and then turns back the bytes into sound waves.
Tip! A financial institution offers MP3 players as an incentive for new accounts. The branded players contain an audio magazine that promotes other investment and money management strategies that compliment their product offerings.

The amplifier also boosts the strength of the signal and then sends it to the audio port whereby you can attach the pair of headphones. Most of the MP3 players are powered by battery.

Is Downloading MP3 From File Sharing Programs Legal?

File sharing programs such as KaZaa, Ares, iMesh and Limewire have never been more popular. They are pretty controversial as well. You may have heard of the countless lawsuits against them by music records companies and the MPAA. So is downloading MP3 from these programs legal?

How Do File Sharing Programs Work?

Modern file sharing programs connects users directly to each other allowing them to share and download files. They are also called P2P, or peer to peer programs. Unlike old file sharing programs such as Napster who ran all connections through their servers. That is also why it is sometimes difficult to determine exactly who is downloading what.

File sharing programs by themselves are not illegal. In fact, they are legitimate uses for it. For example, it is used by academy institutions and universities to exchange research data and cross learning. They are also used by musicians and artists to showcase their talents by distributing their music free through file-sharing networks.

Many people are confused as to what is legal to download and what is not. The problem stems from the fact that it is so easy to download illegal MP3 and other illegal files from these file sharing networks that people often do not know they are actually violating copyright laws.

They do not have sufficient knowledge of copyright laws. Current copyright laws allow an individual to rip MP3 provided he or she has brought a copy of the CD. However, he or she cannot give, sell or upload MP3 to others. Beware due to MP3 piracy, record companies have recently developed technologies that do not allow you to rip mp3 from CD. Add to that, they are dozens of websites on the internet proclaiming to be able to download mp3 and movies legally when they are not!
Tip! An entertainment company includes MP3 players in their press kits touting a new production. Each player is imprinted with the show's icon and includes cast interviews, sound bites and music from the production.

How to determine whether you can download MP3 legally?

Technically, any MP3 posted on file-sharing programs without the permission of the artist is illegal. Most commercial MP3 on file sharing networks are illegal, so my advice would be to avoid them altogether.

There are a few reputable MP3 download sites on the internet you can trust. The most famous of all is itunes from Apple. Napster has a subscription service per month that allows you to download more than two million mp3 legally. Technically, you do not own the mp3 so do not give, sell or upload to file sharing networks. For more information on where you can find more free legal mp3, you can visit my blog.
