Program For Batch Coversion

hello All.
I have a question. do you know some software that make bacth conversion of wav file? A friend of mine has a studio and is getting mad in converting wav file whose frequencies are 7, 11, 22 Khz, 8 bit and so on. the sound card he has cant read lower frequencies…
he would like to have the pitch inalteraed too. ( that is the main feature he need actually…) I guess he is willing to pay to buy one too.

any help appreciated !!
