Buying the Right Mp3 Player

Technology in Mp3 Players

Mp3 is the short form of Mpeg-1 Layer 3. Layer 3 uses perceptual audio coding, and psychoacoustic compression, to take off redundant or superfluous data in a sound signal, thereby massively reducing the warehouse space required. Layer 3 can cut the music files from, say, a accepted Cd, to roughly a tenth of their former size, without compromising the capability of sound. Due to their smaller size, Mp3 files can be literally transferred across the internet, and large numbers of them can be stored on a single Mp3 player.

Key Features
When you pick a player that has high warehouse capacity, you can take more songs with you. The Creative MuVo is a memory flash player, with a capacity of 64 Mb, that can store 15 Mp3 tracks (the equivalent of 44 floppy disks' worth of data), while the Acer Mp330 comes with 10 Gb of memory and added functions. Some Mp3 players supply user interfaces with large Lcd screens, which allow you to find and organise songs easily, and configure the player to your liking. Some come with Id3 tags, containing data relating to the songs. The Sum foresight M18 model, for example, comes with a high-resolution, back lit Lcd screen; the Panasonic Cq-Dfx683N displays Id3 tags. A player's interface determines how it can be associated to a computer (for example, via Usb 1.0, Usb 2.0, or FireWire), in order to change data. Available models include the OraCom Orc200, which has a Usb 1.0 port, and the Ministry of Sound Mosmp043 which has a Usb 2.0 interface, for faster downloads. Some models, such as the Cowon iAudio 4 Cw400, have Jet Shell software, which includes all you need to create, download, and organise music files. There are obviously some compatibility issues between players, so check that your chosen player will run your favourite software. Some Mp3 players not only support Mp3 files, but other formats as well, together with Wma, Wav, Aiff, and Atrac. Some, on the other hand, do not. Again check that your chosen player supports your music format. The iRiver iFp 195Tc, for example, is an industrialized Mp3 player which supports Mp3 and Wma. Some Mp3 players are highly versatile, supporting Fm tuners, video recording, photographic display, and onboard microphones. The Samsung Ypt7X model is adequate with a built-in Fm tuner and microphone functions.
Battery Life

Buying the Right Mp3 Player

Some Mp3 players use rechargeable lithium batteries; some use replaceable alkaline batteries, and others charge straight through a Usb cable, capable of transferring both power to the player. Memory flash players commonly have a battery life of 20 to 60 hours, while hard drive or multimedia players' batteries commonly last around 14 hours. The Philips Key005 recharges straight through a Usb cable, for over six hours of playback. The Sony Nwhd3S has a 20 Gb hard drive and up to 30 hours of battery life.

Conclusion

The latest Mp3 players supply a suitable recipe of storing and accessing your favourite music. There are many brands and models on the market, but make sure that the one you pick is the best for you. For example, if you're going to motivate yourself whilst jogging or working out, pick a memory flash player, without attractive parts. Think thought about about how you will use your chosen player; shop around, and find a value-for-money player that best suits your needs.
