Music and file sharing

In this part of my site you will find details on my products in relation to music and file sharing.

The MP3 format is a compression system for music. This format helps to reduce the number of bytes in a song, without hurting the quality of the song's sound. The goal of the MP3 format is to compress a CD-quality song by a factor of 10 to 14, without losing the CD sound quality. A 32-megabyte (MB) song on a CD compresses down to about 3 MB on MP3. This lets you download a song in minutes rather than hours, and you can store 10 to 20 songs on an MP3 player using a relatively small amount of memory.

Many people who start collecting MP3 files find that they want to listen to them in all kinds of places. Small, portable MP3 players answer this demand. These players are like portable cassette or CD players, except that they are smaller and they use solid state memory instead of a physical medium like a tape or a CD. All of the players currently on the market include a software application that lets you transfer your MP3 files into the player. Most of them also include utilities for copying music from CDs or Web sites, and the ability to create custom playlists.

The MP3 player is a wonderful example of a new use of existing technologies. None of the components in a typical MP3 player is radical, or even newtechnology. By simply combining these components in a new way, and writing some code to control it all, manufacturers have created an entirely new line of consumer products!

• Pull the song from memory byte by byte
• Decompress the MP3 encoding
• Run the decompressed bytes through a digital-to-analog converter
• Amplify the analog signal so you can hear it
