Following complaints about audio distortion problems when playing CDs via iTunes, Apple has released an update today to fix the issue as well as bring unspecified enhancements to iTunes Match. This update to iTunes version 10.5.2 is available for download today on both Mac and Windows.
The last update to iTunes 10.5.1 brought the iTunes Match feature, which lets you store your entire music collection in the iCloud, whether or not all the music was purchased through iTunes. Songs that matched those already in Apple's libraries are streamed from 256kbps master copies, while songs that cannot be matched are uploaded for streaming.
iTunes 10.5.2 brings some improvements to iTunes Match, but mainly addresses the audio distortion problem that several users have experienced while trying to play or import certain CDs. The update for Mac computers requires OS X 10.5 or above, while the Windows version of the update comes in either 32-bit or 64-bit.
