Try this totally free and great audioformats conversion Utility:
https://www.mediahuman.com/audio-converter/
I just tested .caf to .wav Batch conversion with this Utility and it seems to convert a whole folder of .caf factory Apple Loops very fast to .wav files, no problem.
However, i dunno about the mediatags in the .caf files..
They problaby won't get transfered to the wav files during conversion with this Utility.
(Sorry, i can not test this).
Hope this is helpful !
