    Hello all,

    Am having problem with a new gadget i've gotten. See details here: http://www.boards.ie/vbulletin/showpost.php?p=2231727&postcount=1

    Anyways, as you can see, the problem is regarding when i record with this new gadget off the TV. I only get the audio from the left.

    The video's produced when recorded are Divx AVI's. When i play them on the TV or the gadget's built-in speaker, you wouldn't even notice that there's only audio from the left ear. But as you can imagine with earphones, it's a different story altogether! :rolleyes:

    Anyways, to cut a long story short... i would like to extract the mono audio (left) and duplicate it to the right side. And then merge it back into the video, so now the same audio would be present in both left and right. Understand?

    Doubt it's too difficult to do... but would like tips / advice on how to go about doing this.

    Thanks in advance!

    Open your video file in an authoring package, recreate the audio track as stereo and duplicate the left sound track to the right as well?

    Cheers doodlesketch!

    Any chance you could give me an example of "an authoring package"? VirtualDub (http://www.virtualdub.org/) would probably do it, right?

    EDIT: Never mind doodlesketch. Got it done and working anyways!

    Used VirtualDub to save the audio from the AVI as a WAV. Opened the WAV in a very good free program called Audacity. Re-created the WAV as a stereo track and duplicated the audio from the left channel into the right. Then saved the WAV. Merged with video and newly created audio together with VirtualDub. Works perfectly now!
