Apple's iTunes software is an integral part of transferring files to and from the iPod, iPhone and iPad devices. The iTunes software originally handled just music files, but as Apple's offerings have grown, so has the software. You can now use iTunes to purchase, download and transfer music, video and text content.
Video of the Day
The iTunes software and mobile devices support audio in many formats. Among these are MP3, WAV, AAC, and AIFF. MP3 files are supported with variable bit rates and fixed bit rates from 32 kbps to 320 kbps. Music files are supported with and without Digital Rights Management (DRM) encoding.
The iTunes software supports any video content purchased through the software. User content is supported in any format that is playable in the Apple QuickTime software. MPEG4 file types – including MOV, M4V and MP4 – are supported. Some movie formats are not immediately compatible with your mobile devices, but can be converted through the iTunes software to a version that will be supported.
The iTunes application can also be used to purchase and sync books and documents. Devices supporting the iBook application can use ePub files downloaded from iTunes, DRM-free ePub files from other sources and PDF files.
Mobile Device Support
The iTunes software may be able to utilize some content that your mobile device can not, depending on the version of mobile device you have. Older generations of the iPod may not support as many audio versions. The use of iBooks on an iPhone or iPod touch requires version 4 of the iOS or later.
