But, Firefox doesn't or can't play it because it is native to Windows, at least unable to play it as is, probably because of copyrighted issue with the .wav format or something like that I guess. If I put that in MP3, it's going to be worst. If I put .mov or whatever QuickTime wants, it won't work in the other browsers.

The only one I have seen so far capable of doing that is Flash player but that would require some installation on the PC as well. But, most of the people have it so maybe that would be better than what we have now.
