Have an iTunes library full of uncompressed audio? Then you’re probably familiar with iTunes’ built-in option to automatically convert higher bit rate songs to a lower bit rate—and thus smaller file size—when filling up an iDevice.
Previously, this option was not so audiophile friendly, due to its 128 kbps restriction, but with iTunes 10.6, you have some freedom to lower the file size of AIFF and Apple Lossless files while maintaining better sound quality.
On the Summary page for your device, check down in the Options box, make sure you have the Convert higher bit rate songs box checked, and then take your pick from 128, 192, or 256 kbps, and enjoy the extra space on your device while also enjoying your music.
