[lubuntu] Virtual Surround Sound Software

Hello there

I'd like to ask if you know any program for Ubuntu that mimics Surround Sound on Stereo Headphones. For e.g. my SONY TV has an option called "Dolby Virtual" and though it actually has two speakers, if you choose this option, you are getting the impression that sound comes from more than two sources. Also, i had a similar program on Windows (though i don't recall it's name)

So, is there any Virtual Surround Sound software for Ubuntu to use with your stereo headphones/speakers, or do we have to wait for that?

Thank you
