Editing Windows Media Player (section)

===Portable device sync===
Windows Media Player allows the user to connect, share and sync data with portable handheld devices and [[game console]]s since version 7. Media can be optionally transcoded to a format better suited for the target device, automatically, when synchronizing. When deleting playlists from devices, Windows Media Player can automatically remove their contents. Devices can be formatted using Windows Media Player 9 Series and later. Version 10 and later support the [[Media Transfer Protocol]] and Auto Sync. Auto Sync allows users to specify criteria such as recently added music or highest rated songs, by which media will be automatically synchronized with the portable device and other advanced features like setting the clock on the portable device automatically, communicating with the device to retrieve the user's preferences. Windows Media Player 10 also introduced the [[User-Mode Driver Framework|UMDF]]-based ''Windows Portable Devices'' API.

Version 11 has improved synchronization features for loading content onto [[PlaysForSure]]-compatible portable players. WMP 11 supports reverse-synchronization, by which media present on the portable device can be replicated back to the PC. ''Shuffle Sync'' can be used to randomize content synced with the portable device, ''Multi PC Sync'' to synchronize portable device content across multiple PCs and ''Guest Sync'' to synchronize different content from multiple PCs with the portable device. Portable devices appear in the navigation pane of the library where their content can be browsed and searched.

Windows Media Player's 'Sync' function has options that allow it to be set to automatically down-convert (transcode) high bit-rate song files to a lower bit-rate. This down-conversion function is switched on by default. This is useful for providing low bit-rate files to those portable devices that need them, and to save space on portable devices with smaller storage capacities. For high bit-rate capable devices with sufficient storage capabilities, the down conversion process can be omitted.

In versions 11 (2006) and 12 (2009), the Quality settings that the user has selected in the Windows Media Player settings for Sync, for that specific portable device, are used to control the quality (bit-rate) of files that are copied to the portable device. Leaving the Quality settings to Automatic will often result in 192kbs files being copied to the portable device. Manual settings can also be made. 192kbs is the highest quality down-conversion bit-rate that can be manually selected when the Sync function's down-conversion function is turned on. Lower bit-rates can also be selected.

For portable devices that can handle high bit-rate files, the best quality files are obtained by leaving the down-conversion process switched off (unchecked) for that specific device. In Windows Media Player Version 11, switching off the down-conversion function is done in the Quality tab of the Advanced Options of the Sync settings for the device. In Windows Media Player Version 12, switching off the down-conversion function is done in the Quality tab of the Properties for the device in the Select Settings for the device in the Sync Options menu.

When set up in such a way, Windows Media Player's 'Sync' function can be used to sync unchanged high bit-rate song files to suitable portable devices (i.e. those capable of using file formats such as WMA Lossless, mp3-360kbs, etc.). For example, some users have created large song libraries on their PCs containing .wma formatted song files using the high bit-rate WMA Lossless (WMA-LL) protocol, or using other high bit-rate song file formats. The WMA-LL protocol is selectable in Windows Media Player as an option when ripping songs from CDs. The resulting bit-rates seen on ripped WMA-LL files are often 3 to 6 times higher than 192kbs, and can typically fall anywhere in the range of 600kbs to 1200kbs, depending on the quality of the source file that was present on the CD in the first place. The sound quality is much improved over the default rate, although the file size is larger.

At the time that Versions 11 and 12 were released, the capabilities and capacities of portable devices typically required down-conversion of the bit-rates of the files placed on the portable devices. Thus, Sync down-conversion was turned on by default. This was to ensure playability of the files and to ensure that the file sizes were small enough to efficiently fit a reasonably large selection of songs on the portable device.

In recent years (circa 2012), portable devices became available that could natively play these Windows Media Player produced high bit-rate WMA-LL files (and others), and that have storage capacities suitable for large collections of high bit-rate song files. This made it much more practicable and desirable to use software programs such as Windows Media Player to synchronize previously PC-bound libraries of high bit-rate songs to these new portable devices.
