How I've used SpectraLayers Pro 5 to make some mono2stereo conversions. This is not a complete demo, but should give you a quick feel for using the program. I use Del Shannon Runaway during this demo. There is a stereo version of this song by Del, but it's not the HIT version of the song. That version is rip for a complete DES convert.
