Saves space while retaining quality

A minor new feature of iTunes 10.6 is the ability to choose higher bitrates when downcoverting files for sync, notes AppleInsider. On an iOS device's summary page, the "Convert higher bit rate songs" checkbox now includes a drop-down menu offering 128, 192, or 256kbps AAC options. Previously iTunes limited downconversion to 128kbps.

While iTunes Store music is already encoded at 256kbps, the new options may be useful for people who have imported 320kbps files into iTunes. Simply converting to 192kbps can potentially save several gigabytes of space on a device, which may be important as Apple continues to sell products which sometimes have 16GB or less of onboard storage. Some rumors had Apple making the leap to a 32/64/128GB lineup with the third-generation iPad.
