5.1 Mix from Stereo Sources

Folks,

I'm sure this has been asked before but I've searched and haven't found a good answer yet. Perhaps there's a problem with my setup.. Seems like it should be ok.

I'd like to figure out how you "create" a 5.1 sound track from stereo sources.

Say I have the stereo source from my Canon HF100 camera that I've dragged in attached to the AVCHD clip.

Then I lay a stereo MP3 track underneath it.

I'd like the stereo MP3 track to play to all 5.1 destinations with a slight lean toward the front and I'd like to take the AVCHD audio clip and push it more toward the center channel.

The audio properties for my timeline are 5.1. When I drag the surround pan for each track to the place I want I don't get the desired result. (i.e. when I try to drag the AVCHD audo to to center channel only or maybe just the rear surrounds only I don't get playback JUST from those speakers. I can pan across the front channels ok but I can never isolate the center channel or isolate just the rear channels.

I'm using Vegas Pro 8.0c on Vistax64 with and Asus P5E mainboard and Supreme FX II sound card dumping to Logitech G51 5.1 speakers.

Can someone point me to a good tutorial or perhaps tell me what I'm clueless on here? (I.ve seen some that seem to say that it should be just as easy as dragging the surround panner to wherever you want the audio to play) but that doesn't seem to be working for me.

thanks, -mgm

If you double click on the surround panner it will expand. Click a speaker icon in this panner & it will toggle that speaker on or off. There are also different pan types.

Hope this is helpful.

Yeah, there must be something weird wrong with my setup. I can do as you suggest but if I turn every speaker off except for the center channel, all of my output is through the left front and left rear speaker.

If I try to isolate just the front right speaker I get playback through both the front right and rear right. If I isolate the rear right I get playback through both right speakers (front and rear).

I guess I'll have to dig further. I don't have any of that crazy Matrix sound turned on and all EQ settings through the BlackHawk SoundMax software is off...

Thanks for the suggestion though.

What panning model are you using?

Look at preferences, audio device. What device, what drivers, what output mapping?

Thanks that did it. I changed to the "Direct Sound Mapper" and we are cooking with gas.

The Microsoft Sound Mapper and the Windows Classic Wave Driver mess things up.

I'm getting some spittering and sputtering of the sound track during playback but I guess that will be my next problem to find a solution for.

thanks for the direction.
