5.1 Surround Sound

Hello.

I would like to start working in 5.1 surround sound.

I will be starting with a stereo video track from my camera and then through editing in Premier Pro CC, would like to end with a 5.1 audio track where the Center, Left and Right  channel will have the audio from the camera in its original recording  and the music and sound effects will be mixed to the Left and Right channels and also to the Ls and Rs channels

Where could I find information to do that?

Thanks for info.

Bert
