Fluke is a small utility for Mac OS that lets you play FLAC files right within iTunes.

Features

• 16bit/44.1KHz playback
• Multiple file and folder handling (the latter from command line only at the moment)
• Track number and count support

Known issues

• Only 16bit/44.1KHz files play fine. Any other resolution affects the speed of playback which is a known Xiph.org issue.
• Embedded artwork is not supported. However if you've got an iTunes Store account, select the songs you added, right-click and hit Get Album Artwork.
• iPods, iPhones and Airport Express are NOT supported — Fluke uses a third-party library not available on those devices.
• CD burning does not work for the same reason as the above.

TODOs

• Folder handling via GUI
• Offer option to convert to Apple Lossless on the spot
