Perhaps the song is encoded in a format that the iPhone does not support. The iPhone supports audio files of the following formats: .aac (m4a, m4b, m4p up to 320 Kbps), Apple Lossless (high-quality compressed format), .mp3 (up to 320 Kbps), .mp3 Variable Bit Rate (VBR), .wav , .aa (audible.com speech, formats 2, 3 and 4), .aax (audible.com speech, AudibleEnhanced format), .aiff. This list includes formats for audiobooks and podcasts.
iPhone supports video files of the following formats: H.264 (Baseline Profile Level 3.0), MPEG-4 (Simple Profile).
The song encoded in the Apple Lossless format has the sound quality of a CD, but takes up only half the space compared to a song in the .aiff or .wav format. The same song in the .aac or .mp3 format takes even less space. When you import music from a CD using iTunes, the material is converted to the .aac format by default.
Using iTunes for Windows, you can convert unprotected .wma files to .aac or .mp3. This function is of interest when there are data encoded in the .wma format in the media library.
iPhone does not support .wma, MPEG Layer 1, MPEG Layer 2 audio files and audible.com 1 format.
If you have songs or videos not supported by the iPhone in the iTunes library, you can convert them to a format that is supported by the iPhone. For more information, see iTunes Help.
Creating backup copies
You can create backup copies in the following ways:
- After the iPhone is configured to synchronize with a specific computer, iTunes automatically creates an iPhone backup on this computer when synchronizing. iTunes does not automatically backup an iPhone device that is not configured to sync with this computer. If you have configured iPhone to automatically sync with iTunes on a particular computer, iTunes will back up your iPhone every time it connects to your computer. Automatic synchronization is enabled by default. iTunes creates only one backup each time the device is connected, even if the synchronization was performed several times before the disconnect.
- If you decide to update the software on your iPhone, iTunes will automatically back up your iPhone, even if it is not configured to sync with iTunes on this computer.
- If you decide to restore the iPhone software, iTunes will prompt you for an iPhone backup before recovering. If you use a Bluetooth headset or car kit from an iPhone and you restore the setting, you must reconfigure it to pair with the iPhone to use the Bluetooth device.
Restore from a backup
You can restore settings, downloaded programs and other information from a backup or use this function to transfer these items to another iPhone device. For this:
- Connect iPhone to a computer with which you normally synchronize.
- In the iTunes sidebar, select iPhone and select the "Overview" tab.
- Select "Restore" to reinstall the iPhone software, restore the default settings and delete the data stored in the iPhone. In iTunes, you can also restore from backups without deleting data stored on the iPhone.
Deleted data is not available via the iPhone user interface, but they are not permanently erased from the iPhone until they are replaced with new data. When prompted, select the option to restore the settings, downloaded programs and other information from the backup and select the backup you want to use. Multiple backups are listed separately for each device in chronological order, the most recent backups are listed first.
Deleting a backup
You can delete the iPhone backup from the backup list in iTunes. This may be required, for example, if a backup was created on another user's computer. For this:
- In iTunes, open the iTunes settings. For Windows, select: Edit / Settings. For Mac, select iTunes.
- Select "Devices" (iPhone connection is not required).
- Select the backup you want to delete, and click "Delete Backup".
- Confirm the deletion of the selected backup copy by clicking "Delete backup".
- Click OK to close the iTunes Settings window.
Update and restore iPhone software
You can use iTunes to update or reinstall iPhone software, restore default settings, and delete all iPhone data. If the iPhone is updated, your software is updated, but downloaded programs, settings and songs are not affected. When restoring, the most recent version of the iPhone software is restored, the default settings are restored and the data stored on the iPhone is deleted, including downloaded programs, songs, videos, contacts, photos, calendar information and all other data. In iTunes, you can also restore from backups without deleting data stored on the iPhone.
