YES!  That's it! I have to play with it to get it right- but YES YES YES!  Thank you!!!

LOL Glad you found what you wanted! I made a sample, just a quick test using Disney's Headless Horseman announcement:

http://www.mediafire.com/file/mwrxizhuijr/EchoTest.mp3

I used Sony Sound Forge Audio Studio 8.0, NOT to be confused with the much better and much more expensive Sony Sound Forge 8.0, but it's a decent sound editing application. Audacity is pretty good and Free but I haven't used it much. There're lots of other free and inexpensive apps out there, this is just what I happened to buy.

I don't have "Echo" as an option but "Delay" seems to do the same thing. For this clip I used a 160 millisecond delay with a 60% decay and 30/70 Delay/Original volume ratio. Not perfect but it gives you an idea. I could have added "Reverb" as well but it didn't seem to add anything to the effect, just muddled it up. Maybe with more tweaking...

Anyways hope this helps! Please keep us informed!
