How do I convert AIFF to WAV files on all my .....

You will lose your playlists that you have already created but here goes:

go to Preferences, and choose the CD Import settings - select rip to WAV.

go to the iTunes All Music. Select All. Right Mouse Click, Create WAV version

You will see duplicates being created of your entire library. It will take a while.

When it's done, you should see your original AIFF files are still highlighted - right mouse click on those selection and choose Delete.

Voila - WAV created, AIFF deleted.

I'd suggest backing up your library first.

I have done a couple and the art and order seem unchanged.....your way is a great way to do it all and thanks.

Guys -
Do you think the same benefit applies to WAV vs Apple Lossless? Converted a track last night from Apple LL to WAV. Listening to headphones using BitPerfect and a little NuForce USB uDAC headphone amp, I would be hard pressed to say I could tell a difference between the two. Not trying to dispute Grannyring's preference for WAV vs AIFF, only trying to get educated. Just starting to get into storing (and playing) music on/from an external hard drive.

I have never heard a difference in comparing lossless formats. Usually those that claim they do will either claim they can hear better or have a more resolving system than those who cannot. To me if the differences were really there they would be readily apparent on the lowest common denominator.

Ya, I must be nuts! LOL
