Converting mono mp3 to simulated stereo

[wulf109]

I used to use Easy Cd Creator 3.5 for this but it won't install on Windows XP. Is there any software to do this?

Most video editors let you pan the sound. This is like a balance
control where you can make the sound appear at a certain location
between two speakers. You could locate a certain sound such as a voice
on the left speaker then locate another voice or sound on the right
speaker using the pan or balance audio control.
This would work if one person is speaking at a time. When the person
on the left speaks when you would pan the sound to the left speaker
and pan to the right when the person on the right is speaking. This
can be applied to sounds as well.

You could also try adding stereo background music to make the video
appear to be in stereo.

Some sound processing programs have a simulated stereo feature for
creating a stereo effect from mono sound.

Audacity is free. Maybe it can do it.

Yes, Audacity should do it. An alternative to that is Goldwave. In the save dialog you can choose the output preferences. So: simply load mono audio, save as stereo audio.

You could try WinAmp with a plug in like this one: http://www.winamp.com/plugins/details/97665. You'd probably want the LAME output plug in too.

If you have Cooledit Pro or Adobe Audition or similar wave editor you could make up fake left and right channels with a 3 to 4db ripple response but having the inverse in the other channel. ie a 3db peak at say 700hz in the left channel and a 3db dip in the right and so on at octave intervals. If you added them together you would still have a flat frequency response. The addition of a very moderate amount of reverb would help to widen it out a tad. If you have the facilities to mix the stereo reverb return into counter channels that helps also.

Another way is to find a plug-in that gives you a 45 degree or 90 degree phase shift - some producers do this deliberately on the vocal channel of legit stereo recordings to make it near impossible to "remove the vocal" from releases. There are professional "shuffle" circuits that dynamically modulate a mono signal though ± 90 degrees either randomly or program driven that produce a fake stereo output. But you need a studio and some serious gear to do that.
