The History of MP3 Player In A Nutshell

July 23rd, 2009

MPEG-1 Audio Layer 3 or MP3 for short has become a common audio format that is deployed to transfer and playback music on digital audio player. It was designed by the Moving Picture Experts Group which included amongst others, Fraunhofer of Germany, Thomson-Brandt, AT&T-Bell Labs of USA, and CCETT. It obtained an ISO/IEC standard in 1991.

MP3 reduces the amount of data for recording and yet it maintains the original quality of the uncompressed audio. The MP3 can compress a CD file to one-tenth its size with a mid-range bit rate setting of 128 kbits/s. This compression is done by auditory masking. The first MP3 software encoder was released in 1994. The file extension name was initially .bit which was changed to .mp3 in 1995. Winplay3 was the first real time software released in the same year. Audio files began to be converted to MP3 files and played back in personal computers. MP3 soon spread on the Internet. The release of Winamp in 1997 and the Unix audio player mpg123 in 1998 further popularized MP3. By the later part of 1997, MP3 was being offered free at mp3.com. Peer to peer transferring of music files that are ripped from compact discs rapidly increased. Napster, launched in 1999, assisted large scale peer to peer file sharing. No doubt there was an outcry of violations of copyright leading to loss to recording companies. This was also followed by a spate of allegations and litigations.

There are three categories of MP3 players. These are the hard drives, micro hard drives and flash based MP3 players. The hard drive based MP3 players are heavier and larger. Their capacity is large with ten gigabytes or more and comprises some 2,900 MP3 files. Similar is the micro hard rive based players which has lesser internal storage capacity. It is moreover compact and smaller in size. Their capacity is normally six gigabytes and can hold about 1,700 MP3 files. Both hard drive and micro hard drive based MP3 players run on rechargeable batteries. The flash based MP3 players do not have any moving parts and are very compact. They use minimal power and their capacity is low ranging from 32 megabytes to as much as two gigabytes. Download of music became possible through the Internet when WiFi connectivity was introduced. The first such WiFi Enabled MP3 player was Sandisk Sansa Connect MP3 player.

Unauthorized sharing of music files is extensive. There are also many companies that sell music in MP3 format such as Xiie.net, Juno Records, Bleep, eMusic, Beatport, Zune Marketplace and Amazon.com. Disputes relating to patent and licensing over MP3 involve Thomson Consumer Electronics, Sisvel S.p.A., Fraunhofer Institute, Texas MP3 Technologies, SanDisk, Samsung Electronics, Apple, Alcatel-Lucent and Texas MP3 Technologies, besides others.

Dexter Mania

May 30th, 2009

All kids love cartoons, and my cute, adorable, and sweet little kids are no exceptions. I must admit I love cartoons, too. Even if we have different tastes, we spend most of our evenings watching cartoons. They love “The PowerPuff Girls”, while I’m crazy about “Dexter’s Laboratory”, so we might argue sometimes, but all arguments end with a kiss and a new cartoon.

I have tried to share with them my all-time passion for Disney cartoons, but after a few attempts I had to give it up. They fancy watching Cartoon Network more than watching Sleeping Beauty, so they convinced me to watch TV with them, even if I’m still in love with my classic Disney cartoons. 

Any time we go on holidays, the long journeys make them whine that they are bored, and they miss their cartoons, so they have asked me to buy them some player on which they could load their favorite episodes. First, I didn’t agree, but they kept on pleading and begging until I promised them I would get them an mp3 player with video capabilities.

I have come across the sansa view 8gb , which seems just perfect. Any child could easily use it, so I bought two, one for each girl, so that they wouldn’t fight on them. I loaded them up with their favorite cartoons, wrapped them, and made a beautiful surprise to my kids. Their happy dance when they opened the boxes and saw their new players was worth seeing!

Now, they take their new “toys” everywhere with them. They have learnt quite easily how to load cartoons and music on their players, and they watch them on every trip, and even on breaks, at school. And I can watch my beloved Disney movies without any arguments, any time I want.

My Great Mp3 Player Deal

May 18th, 2009

I’m addicted to my mp3 player, or better said, to the music that’s on it. I must have it with me at all times. I take it with me when I go jogging, and even when I go to the local supermarket. I have had no problems with it and its warranty has long expired, but I don’t plan on changing it any time soon.

Things don’t always go according to plan, however, and my plan of not changing it flew out the window, at the supermarket. Or should I say, flew out of my pocket, like my mp3 player did when the headphone cable got caught in something.

Seeing it hit the ground and break into a thousand pieces made me think of only one thing: I was not going to leave this place until I buy another mp3 player. I went to the electronics isle and started looking for one that seemed suitable. The big mp3 players with large screens did look good, but I didn’t know if I had room for them in my pocket. I was not sure what to get, at all.

I decided to go for the one that was currently on sale, the  2gb creative zen v plus, hoping it was a good deal. The lady at the cash register told me they had sold very quickly, and that I was lucky to catch one. I figured since people were so interested in it, it must be good. My player was a nice green color, that I really liked too.

I don’t regret my decision even for a little bit. It works flawlessly and music sounds much better than it did on my old one. So my misfortune was actually a good thing, since I found something better, at a much lower price than I payed for my old one!
