[ARSCLIST] batch normalization freeware for Macs?

[Ellen Holt-Werle <holtwerle@xxxxxxxxxxxxxx>]

Hello all,
I'm new-ish to the list, having just started dealing with audio 
collections and digital audio issues in the last year or 2.  I was 
wondering if anyone knows or can recommend a free/shareware audio 
editing software for Macs that will do batch normalization.  I was 
recently told of Wavosaur, but that is limited to Windows.
We are working to post oral histories online, and looking at whether to 
adjust the volume levels across all the mp3 files so that they are the same.
Please reply directly.
Thanks very much in advance,
Ellen
