If I recall it was Bradsley
I tried it and it did work good.
You can also check out some winamp plugins, in had one once that did just that.
Now I use Cool edit pro 2.0 and I do stand beside fendermonkey77 in saying that it's an great sound editing tool. Very expensive (much more when you're canadian, curse that damn exchange rate!!)
