You can edit your post also ;)

You have an "edit" feature on the top right of your post which don't force you to post twice ;)

Did you check that link I gave? You didn't say what kinda surround you are looking for. There are quite many.

Surround sound specifications

* 3.0 Channel Surround (analog matrixed: Dolby Surround)
* 4.0 Channel Surround (analog matrixed/discrete: Quadraphonic)
* 4.0 Channel Surround (analog matrixed: Dolby Pro Logic)
* 5.1 Channel Surround (analog matrixed: Dolby Pro Logic II)
* 5.1 Channel Surround (digital discrete: Dolby Digital, DTS, SDDS)
* 6.1 Channel Surround (analog matrixed: Dolby Pro Logic IIx)
* 6.1 Channel Surround (digital partially discrete: Dolby Digital EX)
* 6.1 Channel Surround (digital discrete: DTS-ES)
* 7.1 Channel Surround (digital discrete: Dolby Digital Plus, DTS-HD)
* 10.2 Channel Surround
* 22.2 Channel Surround

From master Strereo track I see it kinda hard to extract multiple isolated audio track (you can't) . To do real, let say 5.1 audio track, you'd need to have left,right,center,rear-left,rear-right and subwoof. To extract those individual tracks from stereo is no-go. That would be some sort of matrix of stereo. So I'd say it's better to stay with stereo if you have one.

two simple words: forget it!

sure it's possible to make surround sound, but thats complete nonsense trying to make digital surround sound..

use the stereo, swith your receiver on pro logic or any other dsp system...

He is absolutely right, forget it.

I work with audio professionally and all I can say is: to create real quality surround sound you need professional equipment and software, everything else is just bullshit. And if you dont have professional equipment/software it is like metlive said: Letting your receiver do the job when watching it is much less work and much better sound. Sorry to say that, but it is true.
We're not in this alone.

I talked to friend of mine who is currently studying audio. He said that you can make 5.1 audio and they have been practicing how to do it.

First you do/copy:
- 2 Stereo tracks (Left, Right/Rear-Left, Rear-Right)
- 2 Mono tracks (LFE&Center)

Insert normally:
- Main (Left&Right)
- Rear channels (left&right), cut low frequencies out and lower the volume, don't need them too loud. They are only there for support. It distracts if they are too loud.
-Center, mix it that you can hear then human voice best. Human voice has a range of approximately 100 Hz to 5000 Hz, but mix it what you hear is the best.
- LFE channel, cut high frequencies. Cut all higher then 80-100Hz. You only need that rumble. You "Feel" this channel, you don't hear it.

Hope this helps you guys. I'm keen to try this in my next project.
