As we all know, there has been a tremendous explosion of MP3 music files in recent times. While the portable MP3 players have been available in the market for quite a few years, it is only lately that stiff competition has compelled manufacturers to add more features and offer them at lower prices.

With sound quality almost unchanged, the benefits of a portable MP3 player over a portable CD player are its physical size and ‘skip-free play’. Since MP3 files are completely digital, you can listen to your favorite music on your portable MP3 player anywhere you choose to – in your car, while running, skiing, mountain biking or, for that matter, any outdoor or indoor activity.

It is understood that portable MP3 player is useless without a computer to go with it. MP3 audio files are passed to a portable player from your computer. Each player comes with its own software that must be loaded on to your computer which enables the two to communicate. Each player has its own requirements for the accompanying computer’s processor speed, Random Access Memory (RAM), operating system and connecting port.

Almost all MP3 players require at least a 90 Mhz processor, 16MB of RAM, a serial or parallel port connection. They will work on Windows 95 and Windows 98 processors. Of course, some players require faster processors and more RAM and there are a few that will work on Windows NT or Macintosh operating systems.

Most portable MP3 players available in the market come with a standard 32 MB of storage space. With an average song of three minutes duration taking up 3 MB space, there is storage for about 10 songs. Some players come with 64 MB of storage or are expandable to 64 MB. Increased storage space is available in the form of a removable memory cartridge. This means that these players are infinitely expandable. It also means, that you are able to use these cartridges much as you would a tape or recordable CD.

Some players come with an array of extraordinary features like built-in microphone for recording, an internal rechargeable battery, an auto shut-off mechanism, a wired remote or a built-in FM radio. It goes without saying that additional features add to the price of the player, so it’s important to find the traits that are needed by you.

With an MP3 player, a consumer can create music lists of his choice and carry thousands of his favorite songs wherever he goes. Some people use the term iPod when referring to an MP3 player. But an iPod is Apple’s version and is not the cheapest MP3 player on the market. But with newer models coming out all the time, it is possible to find a used iPod at a discount. The MP3 players are of light weight and in some cases, weigh less than one ounce. Portability is a large factor in the popularity of the MP3, considering the comfort of carrying in comparison to a CD player. In addition, some devices provide additional technology, like video and photo viewing, alarm and calendar functions, and even cellular phones and Internet service. All portable MP3 players are battery-operated. Most of them come with a lithium battery that is rechargeable and can last between 10-30 hours. A lot of players come with AC adapters that can be plugged into a home outlet and some have DC for cars.

We are living in an era called modern age. Gone are the days that we walk for thousands of kilometers before we reach our destination. Gone are the days that we need to wait for hundreds of days before our letters reach the persons we’re sending. Lots of gadgets abound. One of these gadgets are portable MP3 players. Mp3 players are classified into three: best  portable mp3 player, cheap mp3 portable player, and cheapest portable mp3 player. Whatever classification is your choice, one thing holds true, mp3 players continue to develop from a simple audio player to complex multimedia device. This gadget is capable of showing digital photos, playing moviesand music and a lot more.

Whenever you go to malls or visit shops displaying portable MP3 players, you can’t help but be tempted to own one because of the luxury it brings to your life. When you are there, you will be confronted with the question: Which of the mp3 portable players will you choose. Make sure that when you buy, you pick the right one.

Here are wise tips for you to follow in buying mp3 portable players:

Tip # 1. Know your budget

Do not be an impulsive buyer. I’m pretty sure; you would not like to buy something which you will just regret in the future. “Live within your means.” After all, you will not die if you can’t have a mp3 player. If the best mp3 portable player is too expensive for you, settle with cheap mp3 players, or even with the cheapest portable mp3 player. If you really want the former, wait until your money is enough for you to have it.

Tip # 2. Look for the features that you would often use

Do not buy because a friend of yours has one. Your reason for buying this gadget should be that you can make use of it. Each added feature adds the price that you have to pay. Common mp3 portable players’ features include the ability to play music, video and show photos. There are those which can be used to surf the Internet, check email and play games.

Tip # 3. Examine the software and other removable parts

This must come with the mp3 player that you will purchase. The software must be able to convert your CDs into an audio playback format the player can handle. This is also essential when there is a need for you to reformat your mp3 player in the near future. Removable parts included in the package are Universal Serial bus (USB) connector, charger, and headphones.

Tip # 4. Test before you buy.

Ask an assistance of the salesperson to test his/her product. Ask for instructions as to how to operate the mp3 player you have chosen. Most importantly, ask if there is any warranty. Then, ask for an official receipt.

With the evolution of technology, companies like Apple have developed mini-multimedia devices called iPods. These small, but sturdy hand held media players have captured the attention of the world as they have sold over 42 million in recent years. They can now hold over 60 gigabytes of your favorite music, videos, data and files that you would like transferred from one pc to another.

There are wireless additions and open source software that can customize the operating system to handle applications designed by individual developers. The versatility of the iPods over palm pilots and other similar devices has made them valuable tools for work and play. It has been reported that some medical firms use them to transfer x-rays and client files from one practice to another while also being used to play medical videos for patient care. An iPod in the hand of a forward thinker can become a powerful tool, which can revolutionize work flow within many industries.

Training videos are another great use for the iPod and with the large storage capacity they can be used to coach through many medical procedures. For example, imagine ambulance services with personnel who carry iPods with videos that explain how to give CPR, deliver babies, perform tracheotomies, amputations or any other critical procedure just in case of emergency. This is just one way that this piece of technology can be used to save lives.

There really is no limit to the usefulness of the Apple iPod when creative imagination takes hold of one. There will always be, of course, the regular videos that it can play while you are on an airplane to a foreign country. It can hold more music than the average jukebox found at dance halls and social halls. It even categorizes your favorite genres and will quiz you about the very music downloaded into the iPod.

With wireless technologies becoming cheaper while covering wider ranges of distance, the iPod can keep constant connection within a corporate setting which can synchronize with everyone who uses the same information.

There are companies who can customize your iPod as well so that it matches your company logos or colors. Mostly the iPod will continue to be the toy that teens and young adults use to watch videos and listen to their favorite songs while adults add the customized features listed above. As storage devices, the possibilities are endless. How will you use yours?

For anyone wanting to enjoy their portable DVD player outside of the privacy and solitude of their own room, headphones are a critical accessory. They allow the viewer to listen to movies and music without disturbing those nearby and often act to reduce environmental noise which can intrude on the audio experience. Both comfort and audio quality are important considerations when selecting earphones.

• For those who will be using their portable DVD player to entertain two viewers at a time it is important to assure that the device has 2 headphone ports on it; otherwise a splitter (Y-plug) will be needed.

• Various styles of headphones offer different advantages.

For anyone wanting small, inconspicuous devices any style of in-the-ear headphones can be a good choice. They are often the headphone of choice during activity, but in the case of use with a portable DVD player this is generally not a concern unless it is used for listening to music. Ear bud style headphones are often less comfortable and offer lower quality sound than in-the-canal type headphones. On the other hand, in-the-canal headphones generally require more frequent cleaning. Both require a good fit to offer the best quality sound.

Around-the-ear headphones with earcups can be quite secure and reduce the intrusion of outside sound without consuming additional battery power although they tend to be a bit more noticeable to the wearer than in-the-ear models.

Over the ear headphones help reduce the risk of hearing loss as the signal from in- the-ear devices is amplified by several dB. For comfort, padding over the earpieces and an adjustable headband is recommended. Some users feel that sound quality with over the ear headphones is superior and helps to reduce noise escaping which can disturb others. Some models even offer behind the neck or headband-less styles for added comfort which allows users to don a hat and avoid disturbing their hair. These types of headphones tend to be lighter but also more fragile.

Wireless headphones free the user from wires but have the drawback of using a great deal of battery power in conjunction with a portable DVD player which already consumes a great deal of energy. With wireless headphones, users are also given freedom to move about when listening to music via their player.

Noise canceling headphones are effective at eliminating environmental noise by creating an out-of-phase signal to cancel unwanted outside noise. As this is not a passive process, additional battery power is consumed to achieve this effect.

• A final, but important consideration in selecting headphones for a portable DVD player is to assure that it is compatible with the device. The cord on the earphones must obviously be capable of connecting to the player or an adapter will be needed, adding more weight and bulk where it is not wanted.

Daniel Johansson asked:


Forget DVD-A, SACD and MiniDisc, which have failed to threaten the humble CD. The iPod revolution, computer-based media players and the proliferation of formats such as mp3, ogg and FLAC have provided the catalyst for the explosive popularity of downloading music. It’s here to stay, but how do we integrate new digital media into our homes? This guide aims to outline several methods to break free from listening to such media through computer speakers and portable media players.

For owners of iPods and the like, a docking station provides a low-cost solution to play music through existing HiFi equipment. You’ll also need a 3.5mm stereo jack to RCA (phono) lead to connect from the dock into the back of your HiFi amplifier. The dock can be omitted and the cable used to plug in the headphone out of your mp3 player, but the sound quality is significantly inferior to the lineout connection utilised by a docking station.

FM transmitters are available for mp3 players. This solution allows for more flexibility as any radio receiver in the home can be tuned into the frequency set by these transmitters. They are also the most ideal solution for in-car audio. Highly recommended is the Belkin Tunecast 3, which works with all mp3 players. Beware that the range of these devices is limited and so should be placed in the same room as the FM tuner.

Personal computers are great for storing vast amounts of digital media. The problem is: how do you get music from the study into your living room? Moreover, how do you control what you’re listening to without having to use your computer? Slim Devices’ Squeezebox provides a solution to each of these problems by wirelessly streaming music from your computer to your HiFi system. It is a small box with display and remote that doubles up as an Internet radio player. Unlike the mp3 player FM transmitters, this box can be placed anywhere in the home. Sound quality is excellent and it has been well-received by the audiophile community.

One of the main limitations of the Squeezebox is that is it only designed to stream into one HiFi system. What if you want to be able to play different files at the same time across a variety of different home audio systems? Sonos’ Multi Zone Digital Music System tagline is “Play any song. In any room. From anywhere.” This is a costlier, but ultimate, approach to streaming digital media in the home. As with the Squeezebox, sound quality is surprisingly high fidelity, especially if streaming lossless formats such as FLAC or Apple Lossless.

A Sonos system allows different music to be played in up to 32 rooms! This is enabled by using a “ZonePlayer”, of which two versions are available. One version plugs into your HiFi system, the other is amplified and can be used to drive a set of speakers independently. Using a Sonos controller, which is very similar in operation to an iPod, music can be independently played from room to room, or other rooms can be controlled via one controller. As with the ZonePlayers, up to 32 controllers are supported.

Whether your requirements range from plugging in an mp3 player into your HiFi to installing a true multi-room wireless system, it seems that it is only a matter of time before computer-based music overtakes CD as the dominant format of choice.

David Liu asked:


A digital audio player (DAP), more commonly referred to as an MP3 player, is a consumer electronics device that stores, organizes and plays audio files. Some DAPs are also referred to as portable media players as they have image-viewing and/or video-playing support. MP3 players are now regularly built into mobile phones, making them the most common form of digital audio player. In short, an MP3 player is a portable device that plays digital music files–although many MP3 players can do much more than that. They evolved from the portable cassette and CD players that we carried around in the 1980s and ’90s. Instead of bulky cassettes or scratch-prone compact discs, most MP3 players play files stored directly on the device. Aside from a pair of headphones, there is nothing extra you need to carry to enjoy your music collection.

An MP3 is a digital audio file compressed with a standard defined by the Motion Pictures Experts Group (MPEG). MPEG was formed to develop techniques for dealing with digital video; since most video also contains audio, MP3 was developed as an audio extension of that work. Officially known as “MPEG-1, Layer 3″, MP3 is a lossy compression algorithm that uses psychoacoustic modeling to reduce the size of audio files by up to 90%.

Psychoacoustics takes advantage of deficiencies in the human hearing system to throw away digital bits corresponding to sounds that cannot be heard. The human ear cannot hear soft sounds in the presence of loud sounds having a similar frequency; for example, a voice conversation becomes inaudible when a jet flies low overhead. This effect is known as auditory masking, and done correctly the discarded sounds will not be missed.

MP3 is a lossy algorithm in the sense that the original bits cannot be recreated from the compressed bits. In terms of hearing, however, MP3 is lossless because the human ear cannot distinguish between a CD recording and a properly encoded MP3 version of it. MP3s achieve this transparency at a bit rate of approximately 256 kilobits per second, or roughly one sixth of the 1.4 megabits per second required by the compact disc format.

MP3s can be recorded at lower bit rates, saving even more space, but audible differences begin to appear at rates below 128 kilobits per second. At these lower bit rates, MP3 can use a trick known as joint stereo to improve quality. Audio generally consists of left and right audio tracks. Joint stereo combines, whenever possible, the sounds common to both left and right tracks into one track. Instead of left and right, it has “common” and “different” channels.

Being an open standard, and therefore available to anyone, has played a major role in the widespread adoption of the MP3 file format. While specific implementations such as those by the Fraunhofer Institute may be protected by patents, there exist numerous open source implementations. MP3s were originally only playable on computers, but inexpensive, portable MP3 players such as Apple’s iPod have since been developed.

History

The immediate predecessor in the market place of the digital audio player was the portable CD player, which was sometimes referred to as a “portable audio device.”

Briton Kane Kramer designed one of the earliest digital audio players, which he called the IXI. His 1979 prototype was capable of approximately 3.5 minutes of audio playback but it did not enter commercial production. The related patents expired in 1988. Apple Inc. hired Kramer as a consultant and presented his work as an example of prior art in the field of digital audio players during their litigation with Burst.com almost two decades later.

The first mass-produced DAP was created in 1997 by SaeHan Information Systems, which domestically sold its “MPMan” player in the middle of 1998. The South Korean company then licensed the players to Eiger Labs which distributed them—now branded as Eiger Labs MPMan F10—to the North American market during the summer of 1998. The flash-based players were available in 16 MB storage capacity.

The Rio PMP300 from Diamond Multimedia was introduced in September 1998, a few months after the MPMan. It was a success during the holiday season, with sales exceeding expectations. Interest and investment in digital music were subsequently spurred from it. Because of the player’s notoriety as the target of a major lawsuit, the Rio is erroneously assumed to be the first DAP.

In 1998, Compaq developed the first hard drive based DAP using a 2.5″ laptop drive. It was licensed to HanGo Electronics (now known as Remote Solution), which first sold the PJB-100 (Personal Jukebox) in 1999. The player had an initial capacity of 4.8 GB, which was advertised to be able to hold 1200 songs.

In October 2001, Apple Computer (now known as Apple Inc.) unveiled the first generation iPod, the 5 GB hard drive based DAP with a 1.8″ Toshiba drive. With the development of a minimalistic user interface and a smaller form factor, the iPod was initially notable within users of the Macintosh community. In July 2002, Apple introduced the second generation update to the iPod. It was compatible with Windows computers through Musicmatch Jukebox (now known as Y!Music Musicmatch Jukebox). The iPod series, which grew to include microdrive and flash-based players, has become the market leader in DAPs.

In 2002, Archos released the first “portable media player” (PMP), the Archos Jukebox Multimedia. Manufacturers have since implemented abilities to view images and play videos into their devices.

In 2003 the first MP3 players were installed into mobile phones in South Korea and the first artist to sell songs as MP3 file downloads directly to mobile phones was Ricky Martin. The innovation spread rapidly and by 2005, more than half of all music sold in South Korea was sold directly to mobile phones. The idea spread across the globe and by 2005 all five major handset makers, Nokia, Motorola, Samsung, LG and SonyEricsson had released musicphones. By 2006, more MP3 players were sold in musicphones than all stand-alone MP3 players put together. The rapid rise of the musicphone was quoted by Apple as a primary reason for developing the iPhone. In 2007, the installed base of musicphones passed the 1 billion level, and today more than half of all moblie phones in the world have an MP3 player.

Although online music services such as RealNetworks’ Rhapsody also offer legal downloads through a subscription plan, the launch of the iTunes Store in 2003 established the model of selling individual songs and albums for purchase.

Operation

Digital sampling is used to convert an audio wave to a sequence of binary numbers that can be stored in a digital format, such as MP3.

Common features of all MP3 players are a memory storage device, such as flash memory or a miniature hard disk drive, an embedded processor, and an audio codec microchip to convert compressed sound into analogue form that is then played through the speaker jack.

Most DAPs are powered by rechargeable batteries, some of which are not user replaceable. Listening to music stored on DAPs is typically through earphones and stereo systems connected with a 3.5 mm jack.

Types

Digital audio players are generally categorized by storage media:

Flash-based Players: These are non-mechanical solid state devices that hold digital audio files on internal flash memory or removable flash media called memory cards. Due to technological advancements in flash memory, these originally low-storage devices are now available commercially ranging up to 32 GB. Because they are solid state and do not have moving parts they require less battery power and may be more resilient to hazards such as dropping or fragmentation than hard disk-based players. Basic MP3 player functions are commonly integrated into USB flash drives.

Hard drive-based Players or Digital Jukeboxes: Devices that read digital audio files from a hard disk drive (HDD). These players have higher capacities currently ranging up to 250 GB. At typical encoding rates, this means that thousands of songs can be stored on one player.

MP3 CD Players: Portable CD players that can decode and play MP3 audio files stored on CDs.

Networked audio players: Players that connect via (WiFi) network to receive and play audio.

Common audio formats

MP3 is the dominant format, and is nearly universally supported. The main alternative formats are AAC and WMA. Unlike MP3, these formats support DRM restrictions that are often implemented into files from paid download services. Open source formats, which are completely patent-free, are available – though less widely supported. Examples include Ogg Vorbis, FLAC, and Speex.

Most players can also play uncompressed PCM in a container such as WAV or AIFF.

Controversy

Although these issues aren’t usually controversial within digital audio players, they are matters of continuing controversy and litigation, including but not limited to content distribution and protection, and digital rights management (DRM).

Lawsuit with RIAA
