How do you batch export multiple wav to their exact lengths?

So I have a collection of 30 or so tracks that are WAV 44.1 16bit and I would like to turn them into AIFF 48kHz 16 bit.

I’d rather not do this one by one. Isn’t there a way to batch export all wav files into AIFF without the “Export Range” involved? Meaning I CAN batch export them all to AIFF…BUT they would all be the same length as my “Export Range”. I need them to all be the same length as their original wav file was. And that varies track per track.

Any thoughts?
