1. The Digital Music Revolution By Brian Kerschner

2. The MP3 The MP3 owes its incredible popularity to one basic fact, it puts music into manageable files which can be downloaded through an internet connection The MP3 owes its incredible popularity to one basic fact, it puts music into manageable files which can be downloaded through an internet connection

3. How Does the MP3 Work? Well… - The MP3 is a digital audio codec, that is it’s a method of compressing and then decompressing digital sound - The MP3 is called a Lossy Codec because certain portions of the data which are judged to be less essential are removed and cannot be restored upon playback. This allows the MP3 to be a more compact file format - Alternatively, if a codec can reproduce the original data with no loss of quality, it is called Lossless

4. But just how compact is the MP3? In standard CD format, one minute of music takes up about 10 MB, In standard CD format, one minute of music takes up about 10 MB, In MP3 format, that same minute of music only takes up about 1 MB In MP3 format, that same minute of music only takes up about 1 MB

5. Where can you play MP3 files? On your personal computer On your personal computer On MP3 CD’s with the appropriately featured CD player On MP3 CD’s with the appropriately featured CD player On portable digital music players On portable digital music players While these portables are sometimes called MP3 players, most players support a number of audio file types While these portables are sometimes called MP3 players, most players support a number of audio file types

6. 3 Popular File Formats MP3 -The most popular codec for storing and transferring music WMA - Developed my Microsoft - Windows Media Audio is one of today’s most popular audio formats. - Though it is not currently as popular as the MP3, WMA tends to outperform MP3 in the area of sound quality.

7. 3 Popular File Formats - This performance advantage makes it a good file format for portable digital audio players, where total play time is limited by a finite amount of internal memory AAC - An up-and-coming compression format for digital audio. - AAC is the audio file format used by Apple in their popular iTunes Music Store

8. 3 Popular File Formats - In terms of sound quality and data efficiency AAC solidly beats the still popular MP3 format - This is not surprising however since AAC is a newer, more advanced form of compression

9. The Rise Of The Digital Music Player Now that quality music downloading services like the iTunes® Music Store, BuyMusic, and Rhapsody™ are available, pocket-sized MP3 players are more popular than ever. That's because the right portable lets you take your PC audio with you wherever you go. Digital Music players include enough memory to store at least an hour or two of your favorite tunes — and some can store hundreds of hours' worth!

10. Types of Digital Music Players Flash Memory - A very compact form of storage - It cannot skip because its “solid state” memory, so players that use this type of storage are good for jogging, exercise etc.

11. Types of Digital Music Players - This type of storage is significantly more expensive than hard drive storage so players using it typically have storage measured only in megabytes

12. Hard Drive - This type of storage stores music on a miniature hard drive - It stores more music but is often bulkier than flash memory,

13. Types of Digital Music Players - Since these players contain moving parts, they technically are susceptible to skipping, but most of these players incorporate memory buffers that virtually eliminate skipping - Players using this kind of storage usually have larger LCD screens where you can see an interface designed to give you easy navigation of an entire library consisting of hundreds or thousands of songs. - If exposed to electric shock or a powerful magnet, these hard drives can be erased. This is extremely unlikely but possible nonetheless

14. 4 Popular Hard Drive Players There are now more than enough digital music players out there to accommodate unique preferences and individual needs There are now more than enough digital music players out there to accommodate unique preferences and individual needs Here we conduct a survey of 4 popular hard drive players, because while there are dozens of small storage, flash memory players on the market, there are relatively fewer hard drive based players, and therefore the competition is even closer in this market Here we conduct a survey of 4 popular hard drive players, because while there are dozens of small storage, flash memory players on the market, there are relatively fewer hard drive based players, and therefore the competition is even closer in this market

Conclusion of Survey The iPod and the iPod mini are still the best choice for ease of use and aesthetics The iPod and the iPod mini are still the best choice for ease of use and aesthetics Of the two, If your music library is significantly bigger than 4GB, the iPod is the better choice, especially because of the negligible price difference between the iPod Mini and the original iPod Of the two, If your music library is significantly bigger than 4GB, the iPod is the better choice, especially because of the negligible price difference between the iPod Mini and the original iPod But if you value compact size and portability more than high capacity, the iPod Mini could be your new best friend But if you value compact size and portability more than high capacity, the iPod Mini could be your new best friend

The other music players surveyed surely give the iPod a run for its money. Thank you Consumers who don’t want an iPod should feel good knowing there are some legitimate alternatives.
