There is a very effective, inexpensive product called The Amazing Slow Downer, by Ronimusic. Roni is both a musician and a programmer. The advantage over RealBand is that RB could take a long time to make a single speed adjustment depending on how many audio tracks there are and whether or not they are stereo or mono.

With Slow Downer, speed and pitch adjustments can be done on-the-fly and are instantaneous. It's a pleasure to use. Download a trial version at

There are sites that claim to give a free download. One of them is http://en.softonic.com/s/amazing-slow-downer-full-version

I cannot vouch for any of the sites offering a full version for free.
