The entertainment industry has seen many inventions, but the emergence of the software music standard MP3* has turnedthe music world on its head. This is a format that permits high quality music to be transferred from the Internet into people's home computers.
In 1989, the work of German student KarlheinzBradenburg on digital compression and perception of music led to the MP3, a file format that compresses audio into manageable digital files.
The Walkman pioneered portable music but you had to carry tapesor CDs. The MP3 was definitely a breakthrough. Imagine squeezing all your tapes and CDs onto a small drive and having hundreds of songs in your pocket selected with a simple click, easy to copy andemail!!!
The iPod is the quintessencial MP3 player. The i denotes Apple´s internet products. Pods are very small containers: peas grow in pods; spaceships carry escape pods.
Are MP3s goodquality?
No. In order to squeeze CD tracks into 3 or 4 megabytes, MP3 remove frequencies inaudible to humans, compressing the remaining information. Audio purists considerMP3 sound quality impoverished.
There are also questions about longevity. Although vynil deteriorates with use, Thomas Edison´s original cylinders are still playable. Recently, old CDs are becomingerratic from oxidizing or bronzing. Are computer drives such as iPods secure? We won´t know until the technology grows older.
