Try this program, i didnt check it put but it looks good..
Its a free trial program for 30 days......
Heres what to do to make ur program working for more than 30 days, u have to install it, then u will need to change ur computer's current date to an earlier one, like 15 days before for example. This way, every time the program trial date tends to expiry, u change the computer date back to an earlier one and then u will have extra days.....
hm don't know wether this works but just try it out. here --> http://www.samplitude.com/de/v7_demo.htm (17 MB - english) you'll find a limited version of Samplitude - a very good program for music editing. It's although used at radio stations. I know that adding or reducing basses is no problem with the full version but I can't say how much functionality the demo has got ... try it!
