How to copy left audio channell to the right one?

[hellboy80]

I have a video with sound in left audio channel only. I need to copy this sound from left channel to the right channel. How can I do that? Thanks for any help!

Just right click on the event > channels > left only

This will leave you with a mono event.

Actually if you click "combine" it will play over both channels.
