I thought I duplicated and placed it with precision, but I could be wrong. Anyway, after I moved it, and noticed the echo, I used the numpad 4 or 6 to nudge the sound track around but still get the echoing. I honestly think it is just an effect from having the exact same sound coming from two speakers, but I also see your point that it really sounds like the tracks are not perfectly aligned. Other than nudging the tracks and searching for perfect alignment, is there anything else I can do to try to line up those tracks? Is there a half-a-pixel nudge?

You were right on the money with your other point. On the original track there is sound coming from both sides, even though it is a left side dominated (normal for mono sound). It is so much concentrated on the left that I did not listen closely to the right speaker. I think I'm going to delete that second track. I will remember how that sounded in case I ever need to do a video that sounds like the person is in a large stadium. Thanks for your help.

If you duplicate the track, everything will be aligned. If you duplicate the event (with Ctrl+drag), there is a default snap position directly aligned with the original. To align an event already copied that is out of alignment, set the cursor to the beginning of the original event; this will create a snap point for the new event, which will also put it into alignment.

NumPad 4/6 nudging will typically be a single video frame (~1471 samples), which is *plenty* to introduce phasing/flanging/echo effects. To enable more precision, turn off "Quantize to frames" in the options menu, and it will move by pixels (the amount of time per pixel is, of course, zoom dependent, so use the up/down arrows to set the zoom).

I'm curious why you think a mono file is left-channel dominant? It should be equal power from both channels. Perhaps you speakers are not set up property; check the Master meter in Vegas to see that equal power is going to both channels.

Finally, if you even want to re-create the echo effect, you can do the duplicate event trick, but there are also FX just for that purpose, such as Chorus, Delay, Flange/Wah-wah, and Reverb.

I have always thought that sound recorded mono would be predominately or completely on the left channel. I wonder why when one is plugging a mono source into a stereo receiver it is most often suggested that the mono source be plugged into the left stereo channel? Anyway, that probably has no relevance. Thanks for the additional knowlege on sound.

I never did get that second audio track to sound good with the first one. I had quantize to frames off already. I tried nudging and deleting and reinserting but no luck. The sound I am hearing is not a true reverb, which generally has a ringing sound to it, instead this sound is simply a sound that has a funny spacial effect to it. Like listening to a radio and then dialing a phone number that has hold-music that is tuned to the same station you're hearing in the other ear. It's not a reverb, but the perfect matching of the two sounds causes a spacial effect. I wish copying that track had worked because although it didn't sound right, it did create some extra volume that I needed for this project.

Maybe somebody else who likes to play with audio could try what I tried. Put a mono recoreded event on a Vegas track and then duplicate it in another track. Pan the original track fully left and other track fully right and see what you hear.

2Road:

The reason some stereo audio gear have you plug a mono signal into a marked jack (often the left) is because the jacks are wired such that if *only* the marked jack is used, the same signal gets routed to both channels. In software, we don't need special wiring or "left channel only" tricks to route mono to both channels, it's automatic.

If you need additional volume, there's also the track volume control and the master bus volume control. Just don't turn them up so loud that you clip (0.0 dB, red readout).
