mon-stereo

You can put a small amount of delay on one side. Not as in echo, but as in having one side play a fraction of a second after the other. I was looking at the Voxengo StereoTouch plug-in and this is one of the ways it processes audio to create a stereo image from a mono track.

You might even want to try out the plug-in, even if only to see what it does and how it does it.

I went to try the suggestions here. If I try to use Audio Editor, (Coolefeit 2000), then Cooledit has a hissy fit and shuts down. So I export the mono track but it exported as stereo???). The two stereo tracks look identical. It looks like mono in Sonar and I can't get it to change. After I exported I could get it into cooledit and dinged around trying to delay one track a little but there isn't a nudge thingy in cooledit so I'm trying to cut and paste one track a little later and so far it's just ugly.

I think maybe Cooledit can't take it out of Sonar because I did a lot of nudging on it to line it up. It's a vocal track and off beat quite a bit. I'm wondering if the export preserves the nudging. Does it?

If I change a mono to stereo is there any way to change one side to get the "presence" of a normal stereo track?

Here's a technique described in a recent issue of Sound on Sound.  I believe you have all the tools in Sonar Producer to do this, but it takes several plugins.
 
Delay the mono signal 20 to 50 milliseconds and put a high pass filter on the delayed portion to remove anything below 100 Hz (as I recall ... maybe want to set that ever higher).  Let the undelayed signal become the M part of an M/S stream and the delayed and filtered one become the S part.  Season to taste with the signal level on the S part.  Reconstruct the M/S signal as stereo.  Result is complementary comb filtering that can be collapsed to mono with no degradation but has audible tonal differences between the L and R stereo channels.  I'm pretty sure Channel Tools will do the M/S to stereo reconstruction, but I've not actually tried this.

Got a stereo version into cooledit. Cooledit2000 has a nifty  delay function. You can delay ether track by whatever you want then mix them any proportion you want. I found a delay of 30ms left track and a 50/50 mix worked pretty well. I can see I could spend hours dinging around with it though. Also tried inverting one track but that didn't work. Tried adding some reverb to one tract too then decided I had better things to do. So I didn't get to using high pass filter as someone suggested.
