They are used to directly transfer content from external devices, and expanding the storage capacity of PMPs.
A standard PMP uses a 5-way D-pad to navigate, however there have been many alternatives used. Most notable are the wheel and touch mechanisms seen on players from the iPod and Sansa series. Additional buttons are commonly seen for features such as volume control. As well, resolutions also vary, going up to WVGA. Most screens come with a colour depth of bit, but higher quality video oriented devices may range all the way to bit, otherwise known as True colour , with the ability to display Screens commonly have a matte finish but may also come in glossy to increase colour intensity and contrast.
More and more devices are now also coming with touch screen as a form of primary or alternate input. Certain devices, on the other hand, have no screen whatsoever, reducing costs at the expense of ease of browsing through the media library.
Some portable media players include a radio receiver , most frequently receiving FM. Features for receiving signals from FM stations on MP3 players are common on more premium models.
Some portable media players have recently added features such as simple camera, built in game emulation playing Famicom or other game formats from ROM images and simple text readers and editors. Newer PMPs have been able to tell time, and even automatically adjust time according to radio reception, and some devices like the 6th-gen iPod Nano even have wristwatch bands available.
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 the compressed file into an analogue sound signal.
During playback, audio files are read from storage into a RAM based memory buffer, and then streamed through an audio codec to produce decoded PCM audio. Typically audio formats decode at double to more than 20 times real speed on portable electronic processors ,  requiring that the codec output be stored for a time until the DAC can play it. To save power, portable devices may spend much or nearly all of their time in a low power idle state while waiting for the DAC to deplete the output PCM buffer before briefly powering up to decode additional audio.
Most DAPs are powered by rechargeable batteries , some of which are not user-replaceable. They have a 3. Some devices also contain internal speakers, through which music can be listened to, although these built-in speakers are typically of very low quality. Nearly all DAPs consists of some kind of display screen, although there are exceptions, such as the iPod Shuffle , and a set of controls with which the user can browse through the library of music contained in the device, select a track, and play it back.
The display, if the unit even has one, can be anything from a simple one or two line monochrome LCD display, similar to what are found on typical pocket calculators , to large, high-resolution, full-color displays capable of displaying photographs or viewing video content on.
One of the more common methods of control is some type of the scroll wheel with associated buttons. This method of control was first introduced with the Apple iPod and many other manufacturers have created variants of this control scheme for their respective devices.
Some devices simply appear as an additional disk drive on the host computer, to which music files are simply copied like any other type of file. Other devices, most notably the Apple iPod or Microsoft Zune , requires the use of special management software, such as iTunes or Zune Software, respectively.
The music, or other content such as TV episodes or movies, is added to the software to create a "library". The library is then "synced" to the DAP via the software. The software typically provides options for managing situations when the library is too large to fit on the device being synced to. Such options include allowing manual syncing, in that the user can manually "drag-n-drop" the desired tracks to the device, or allow for the creation of playlists. In addition to the USB connection, some of the more advanced units are now starting to allow syncing through a wireless connection, such as via Wi-Fi or Bluetooth.
Content can also be obtained and placed on some DAPs, such as the iPod Touch or Zune HD by allowing access to a "store" or "marketplace", most notably the iTunes Store or Zune Marketplace , from which content, such as music and video, and even games, can be purchased and downloaded directly to the device. A growing number of portable media players are including audio processing chips that allow digital effects like 3D audio effects , dynamic range compression and equalisation of the frequency response.
Some media players are used with Noise-cancelling headphones that use Active noise reduction to remove background noise.
De-noise mode is an alternative to Active noise reduction. It provides for relatively noise-free listening to audio in a noisy environment. In this mode, audio intelligibility is improved due to selective gain reduction of the ambient noise. This method splits external signals into frequency components by "filterbank" according to the peculiarities of human perception of specific frequencies and processing them using adaptive audio compressors. Operation thresholds in adaptive audio compressors in contrast to "ordinary" compressors are regulated depending on ambient noise levels for each specific bandwidth.
Reshaping of the processed signal from adaptive compressor outputs is realised in a synthesis filterbank. This method improves the intelligibility of speech signals and music. The best effect is obtained while listening to audio in the environment with constant noise in trains, automobiles, planes , or in environments with fluctuating noise level e. Improvement of signal intelligibility in condition of ambient noise allows users to hear audio well and preserve hearing ability, in contrast to regular volume amplification.
Natural mode is characterised by subjective effect of balance of different frequency sounds, regardless of level of distortion, appearing in the reproduction device.
The natural effect is obtained due to special sound processing algorithm i. Its principle is to assess frequency response function FRF of mediaplayer or any other sound reproduction device, in accordance with audibility threshold in silence subjective for each person ,  and to apply gain modifying factor. The factor is determined with the help of integrated function to test audibility threshold: The principle is similar to in situ audiometry , used in medicine to prescribe a hearing aid.
However, the results of test may be used to a limited extent as far as FRF of sound devices depends on reproduction volume. It means correction coefficient should be determined several times — for various signal strengths, which is not a particular problem from a practical standpoint.
Sound around mode allows for real time overlapping of music and the sounds surrounding the listener in her environment, which are captured by a microphone and mixed into the audio signal.
As a result, the user may hear playing music and external sounds of the environment at the same time. This can increase user safety especially in big cities and busy streets , as a user can hear a mugger following her or hear an oncoming car. Although these issues are not 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.
But Diamond won a legal victory on the shoulders of the Sony Corp. According to the Scientific Committee on Emerging and Newly Identified Health Risks , the risk of hearing damage from digital audio players depends on both sound level and listening time. The listening habits of most users are unlikely to cause hearing loss, but some people are putting their hearing at risk, because they set the volume control very high or listen to music at high levels for many hours per day.
Such listening habits may result in temporary or permanent hearing loss, tinnitus , and difficulties understanding speech in noisy environments. The World Health Organization warns that increasing use of headphones and earphones puts 1. The report states. They can also limit the time spent engaged in noisy activities by taking short listening breaks and restricting the daily use of personal audio devices to less than one hour.
With the help of smartphone apps, they can monitor safe listening levels. The report also recommends that governments raise awareness of hearing loss, and to recommend people visit a hearing specialist if they experience symptoms of hearing loss, which include pain, ringing or buzzing in the ears. This growing phenomena has led to the coining of the term music-induced hearing loss, which includes hearing loss as a result of overexposure to music on personal media players.

The free service will allow passengers to power and charge an iPod, and view video and music libraries on individual seat-back displays. MIDI files also cannot be played, but can be converted to audio files using the "Advanced" menu in iTunes.
Alternative open-source audio formats, such as Ogg Vorbis and FLAC , are not supported without installing custom firmware onto an iPod e. During installation, an iPod is associated with one host computer. Each time an iPod connects to its host computer, iTunes can synchronize entire music libraries or music playlists either automatically or manually. Song ratings can be set on an iPod and synchronized later to the iTunes library, and vice versa.
A user can access, play, and add music on a second computer if an iPod is set to manual and not automatic sync, but anything added or edited will be reversed upon connecting and syncing with the main computer and its library. The buttons perform basic functions such as menu, play, pause, next track, and previous track.
Other operations, such as scrolling through menu items and controlling the volume, are performed by using the click wheel in a rotational manner. The 3rd-generation iPod Shuffle does not have any controls on the actual player; instead it has a small control on the earphone cable, with volume-up and -down buttons and a single button for play and pause, next track, etc.
The user interface for the iPod Touch is identical to that of the iPhone. Differences include the lack of a phone application. Both devices use iOS. The iTunes Store introduced April 29, is an online media store run by Apple and accessed through iTunes. The store became the market leader soon after its launch  and Apple announced the sale of videos through the store on October 12, Full-length movies became available on September 12, Up to five authorized computers and an unlimited number of iPods could play the files.
The DRM could also be removed using third-party software. RealNetworks claims that Apple is creating problems for itself  by using FairPlay to lock users into using the iTunes Store. Steve Jobs stated that Apple makes little profit from song sales, although Apple uses the store to promote iPod sales. Video games are playable on various versions of iPods. Later revisions of the iPod added three more games: Parachute , Solitaire , and Music Quiz.
In September , the iTunes Store began to offer additional games for purchase with the launch of iTunes 7 , compatible with the fifth generation iPod with iPod software 1. Those games were: Elite Racing and Zuma.
Additional games have since been added. These games work on the 6th and 5th generation iPod Classic and the 5th and 4th generation iPod Nano. Even video game magazines like GamePro and EGM have reviewed and rated most of their games as of late. The games are in the form of. When unzipped, they reveal executable files along with common audio and image files, leading to the possibility of third party games. Apple has not publicly released a software development kit SDK for iPod-specific development.
All iPods except for the iPod Touch can function in "disk mode" as mass storage devices to store data files  but this may not be the default behavior. Unlike many other MP3 players, simply copying audio or video files to the drive with a typical file management application will not allow an iPod to properly access them. The user must use software that has been specifically designed to transfer media files to iPods, so that the files are playable and viewable.
Usually iTunes is used to transfer media to an iPod, though several alternative third-party applications are available on a number of different platforms. Media files are stored on an iPod in a hidden folder, along with a proprietary database file. The hidden content can be accessed on the host operating system by enabling hidden files to be shown.
The media files can then be recovered manually by copying the files or folders off the iPod. Many third-party applications also allow easy copying of media files off of an iPod. While the suffix "Classic" was not introduced until the sixth generation, it has been applied here retroactively to all generic iPods for clarity.
In , Apple faced two lawsuits claiming patent infringement by the iPod line and its associated technologies: The latter case also includes the online music stores of Sony , RealNetworks, Napster , and Musicmatch as defendants.
On August 24, , Apple and Creative announced a broad settlement to end their legal disputes. As part of the agreement, Apple will recoup part of its payment, if Creative is successful in licensing the patent. Creative then announced its intention to produce iPod accessories by joining the Made for iPod program. In January the iPod market share reached On April 9, , it was announced that Apple had sold its one-hundred millionth iPod, making it the biggest selling digital music player of all time.
On October 21, , Apple reported that only PC World says that iPod line has "altered the landscape for portable audio players". Besides earning a reputation as a respected entertainment device, the iPod has also been accepted as a business device.
Government departments, major institutions and international organisations have turned to the iPod line as a delivery mechanism for business communication and training, such as the Royal and Western Infirmaries in Glasgow, Scotland, where iPods are used to train new staff.
Apple offers more information on educational uses for iPods on their website,  including a collection of lesson plans. There has also been academic research done in this area in nursing education  and more general K education. The iPod has also been credited with accelerating shifts within the music industry. The advertised battery life on most models is different from the real-world achievable life. An MP3. Compounding the problem, Apple initially would not replace worn-out batteries.
The official policy was that the customer should buy a refurbished replacement iPod, at a cost almost equivalent to a brand new one.
All lithium-ion batteries lose capacity during their lifetime even when not in use  guidelines are available for prolonging life-span and this situation led to a market for third-party battery replacement kits. Apple announced a battery replacement program on November 14, , a week before  a high publicity stunt and website by the Neistat Brothers.
Fifth generation iPods have their battery attached to the backplate with adhesive. The first generation iPod Nano may overheat and pose a health and safety risk. Affected iPod Nanos were sold between September and December This is due to a flawed battery used by Apple from a single battery manufacturer.
Under an Apple product replacement program, affected Nanos were replaced with current generation Nanos free of charge. A survey conducted on the MacInTouch website found that the iPod line had an average failure rate of It concluded that some models were more durable than others.
In late , many users complained that the surface of the first generation iPod Nano can become scratched easily, rendering the screen unusable. On December 31, , workers at the Foxconn factory in Longhua, Shenzhen formed a union affiliated with the All-China Federation of Trade Unions ,  the Chinese government-approved union umbrella organization. In , a number of workers committed suicide at a Foxconn operations in China.
Apple, HP, and others stated that they were investigating the situation. Foxconn guards have been videotaped beating employees. Another employee killed himself in when an Apple prototype went missing, and claimed in messages to friends, that he had been beaten and interrogated. As of , the iPod was produced by about 14, workers in the U. Further, the salaries attributed to this product were overwhelmingly distributed to highly skilled U.
One interpretation of this result is that U. From Wikipedia, the free encyclopedia. Not to be confused with iPad. For other uses, see IPOD disambiguation. A line of portable media players designed by Apple.
