Hi everyone!

Just wanted to know if anyone of you would have some advice on a good file conversion program, how to, or what to? I have a number of files I am sharing that are homemade music files that I think some people would like. The only problem is they are very large .wav files with a bit rate of about 1.4mbs. This makes for a file size of nearly a Gig for a hour and a half long music file. I would like to shrink that to an mp3 file. I have windows xp and thought maybe I could do that with wmp's musicmatch but with no avail. Could anyone help? Thank you in advance.
