Stereo reversal

Post by andrewgerm »

Hi all
This seems basic enough, but I can't for the life of me figure it out. I have a captured file that has the left and right audio channels swapped. I've split the audio from the video stream, and would now like to swap / reverse the channels. I'd guess this isn't too hard to do? Using VS10+ till I get my 11.

Thanks all :)

AFAIK, this can not be done within VS. To do this you need a audio editor like Audacity (free).

In VideoStudio:
1. Create a Sound File from your Video. (Share>Create Sound File).

Audacity:
1. Open Audacity, select Project>Import Audio
2. Navigate to the audio file you created, select it choose Open.
3. You should now see both channels of your audio track. In the upper left of the audio tracks you'll see an X then to the right of that channels, and a down arrow. Hit the down arrow to produce a menu.
4. Select Split Stereo Track from the Menu.
5. Notice on the far left of each track it identifies which channel the track is (left/right).
6. Now click on the same menu, and you should see Mono, Left Channel, Right Channel. On the Right Channel track, select Left Channel, and vice-versa for the Left Channel.
7. Now Export your audio to a wav file.

Back in VS, in your project, Insert the audio (wav) file you created with Audacity. Viola your channels are swapped.

Had thought of using a an externa program, but was worried about syn problems, i've already multi trimmed as needed.

Thanks though. I'm going to give it a try.

Just move your left speaker to the right, and your right speaker to the left. :wink:

Me going to send my labbi after your labbi for that remark, i think...

Anybody know if this reversal is possible in Media Studio?

solution

Post by andrewgerm »

Ok, I scratched about in VS, and MS, and neither would do this simple little task. I did have a producer tell me I should look at more advanced software for the ongoing work I'm doing. Going to look at MS for a possible future solution to my work.

This current problem...
I did all the cuts, trims, etc, and removed the unwanted footage. Audio was seperated from the video. Exported the audio as a wave file, loaded up in GoldWave, and 'exchanged channels'. Saved this as a wave file, and then imported to the probject in a seperate track. Audio view to make sure that everything lined up correctly, then removed the original track. Now just to render. It's a few mins over 3 hours (captured off VHS) so I'm looking at a long render run again. Captured at 6000, so, with 2 pass, i'm hoping to use variable at 4000, and will encode to ac3 at 320. Thansk for all responses, and hope this solution helps someone.
