Hello everyone, Lin Fei to answer the above questions, Apple synchronization software itunes download, Apple synchronization software itunes many people do not know, now let's take a look!

Friends who use Apple products may be no stranger, Apple synchronization software itunes as a classic product of Apple, Apple synchronization software itunes in functional design and other advantages make it deeply loved by fruit fans. Then, let's learn some information about Apple's synchronization software itunes with Benshaw. We will give you a detailed introduction to Apple synchronization software itunes, the characteristics of Apple synchronization software itunes and the hardware requirements of Apple synchronization software itunes.

A brief introduction to Apple's synchronization software itunes

ITunes is a digital media playback app, a free app for Mac and PC that can manage and play digital music and videos. It was launched by Apple computer at the Macworld Expo in San Francisco on January 10, 2001.

The ITunes program manages content on Apple's iPod digital media player. In addition, iTunes can connect to iTunes Store (if a network connection exists) to download purchased digital music, music videos, TV shows, iPod games, podcasts and standard feature films.

Originally developed by Jeff Robin and Bill Kincaid, it is called SoundJam MP as a MP3 player and was published by Casadi Green in 1999. Acquired by Apple in 2000, it gave it a new user interface and the ability to burn CD, had its recording capabilities, removed panel support, and released it as iTunes. At first, nine months after the release of version 2, Mac OS X only supported Mac OS 9 applications, and with the release of version 3, support for Mac OS 9 was stopped. In October 2003, with the release of iTunes 4.1, Apple added support for Windows 2000 and Windows XP. However, since the release of Microsoft's latest operating system, Windows Vista, Apple has claimed that there are several known compatibility issues with iTunes software. Apple will soon release a new version to solve this problem. Currently, iTunes can run on win7.

ITunes can be downloaded for free from Apple's website, and it comes with all Macintosh computers and some iPod, and is available to Mac OS X. It is also part of Apple's iLife multimedia application suite.

2. The function of Apple synchronization software itunes

Users can compose their music into playlists, edit file information, burn CD, buy music through the built-in music store, download podcasts, back up songs to their computer, run visualization, express vivid effects in time with music, and encode music into many different audio formats.

1. Media management

ITunes stores the metadata of audio files in two files. The first is a binary file called iTunes Library (formerly known as iTunes x Music Library), which uses its own proprietary music library format. It not only buffers the information of artists and genres stored in the tag space of audio files (such as ID3 tags), but also stores some iTunes special information such as "playback times" and "sampling rate". The second file name is iTunes Music Library.xml, which is refreshed when the information in the iTunes changes. It is in XML format and allows developers to easily develop software that can access their information, such as Apple's I DVD, iMovie and iPhoto or Rockstar of freshly squeezed software. The system prevents manufacturers from having any changes to track metadata. Except for metadata such as playback count, Last playback, and sample rate, which are stored in proprietary files, all other information takes effect through the XML file.

two。 Database view

Users can choose different ways to browse iTunes audio and video databases, such as directories, directories with corresponding cover images, grid browsing mode or Coverflow.

3. Database sharing

Songs in the iTunes database can be shared within the local area network using Bonjour (formerly known as Rendezvous)-an implementation of Apple's Zeroconf (which requires ZeroConfiguration) open web standard. This technique allows songs on the same subnet segment to be automatically shared and detected. When a song is shared, iTunes streams it to another computer, but cannot store it to prevent it from being copied. Songs that use copyright protection AAC can also be accessed, but need to be licensed from the iTunes Music Store. A maximum of five users are allowed to connect every 24 hours.

Once in iTunes 4.0, users can freely access shared music over the Internet, not only through the same subnet, but also by specifying the IP address of those remote shared music databases. Apple quickly removed this feature in version 4.0.1, claiming it violated the end user license Agreement (EULA).

Music sharing uses DAAP (Digital Audio access Protocol), a special protocol created by Apple Computer for shared music. DAAP has been solved by reverse engineering, but it is now often used in non-Apple companies.

4. File format support

ITunes 9 can currently read, write, and convert between MP3, AIFF, WAV, MPEG-4, AAC and AppleLossless.

ITunes can also play anything QuickTime can play (even some video formats), including protected AAC files from iTunes Store and Audible.com audio books. In order to play other formats, such as Vorbis or Speex encoding with Ogg, iTunes needs to install the Xiph QuickTime component.

There have been some comments on the quality of Apple's MP3 encoders for coding at variable bit rates. In January 2004, six MP3 encoders with 128kbit/s encoders were doubly anonymous. Roberto Amorim led the public listening test, and the iTunes MP3 VBR encoder ranked last. The leader later confirmed how iTunes was tested with serious problems.

The Windows version of iTunes automatically converts unprotected WMA (including version 9) files to other audio formats, but it does not support direct playback or compiled WMA formats.

5. File metadata

Sound processing

ITunes uses the computer's sound card to play music. ITunes also includes audio processing features called equalizer (equalizing) and "audio enhancement" (sound enhancer), and some languages are also translated as "audio improvement" (sound improver).

6. Video support

On May 9, 2005, iTunes 4.8 was launched with iTunes video support. Users can directly pull video clips from the computer into the iTunes database for classification and management. Videos can be viewed in a small box in the main iTunes window, in a separate window or in full screen. In iTunes, video support is not perfect: although videos in the database are separated from music by small icons on TV or display, they are still put together with ordinary music files and classified by the same music category (such as "album" and "composer"). ITunes is also incompatible with some major formats, including AVI and WMV.

7. Playlist

The third generation of iTunes introduced "smart playlists" to replace static playlists, which can be set to update automatically (online updates) based on a custom list selection criteria (like a database query). The user can set multiple selection criteria to control the playlist.

All users can post playlists on iTunes Store, which is called iMix.

Playlists can be played randomly or sequentially. The "randomness" disorder algorithm can select different tracks from an album or an artist to play (a new feature in iTunes version 5.0). Random party playback can also be played from tracks with a higher rating.

The party random playlist is used as a simple DJ assistant. By default, it randomly selects music from the music library or other playlists; users can override its automatic selection by deleting the music (iTunes will select new music to replace them), or you can add your own music by dragging and dropping or right-clicking the menu. This makes it possible to include both pre-selected and randomly selected music in a playlist. The party random playlist can be intercepted during the run; this allows all randomly selected music to be replaced when the playlist is played.

Third, the hardware requirements of Apple's synchronization software itunes

PC with 1GHz Intel or AMD processors and 512MB memory

Playing HD video requires a 2.0GHz Intel Core 2 Duo or faster processor, 1GB memory, and IntelGMA X3000, ATI Radeon X1300 or NVIDIA GeForce 6150 or later

16-bit sound card and speaker

Broadband network connection is required when using iTunes Store

An iTunes-compatible CD or DVD burner is required to create an audio CD,MP3 CD, or to back up CD or DVD.

Above, we introduce in detail the three aspects of Apple's synchronization software itunes, including the introduction of Apple's synchronization software itunes, the characteristics of Apple's synchronization software itunes and the hardware requirements of Apple's synchronization software itunes. Through the introduction of the above text and pictures, we know that Apple synchronization software itunes, as a classic product under Apple, not only fits perfectly with a series of Apple products in terms of synchronization and other functions, but also performs very well in the functional design of Apple synchronization software itunes.

At the end of this article, I hope it will be helpful to you.
