I have the Plextor Digital Video Convertor and I have quite an old Video Camera.
I have converted the video and sound fine it's just that the Camcorder only has a Mono audio output.

How can I make the audio stereo so it can be played on a Surround Sound System?

The camera is Samsung VP-L600 and the cable I have plugs into the A/V Out and there are two connectors at the end: Yellow (Video) and White (Mono Sound). I don't want to buy another cable.

There is no stereo information in a mono track, but you can simulate stereo using an audio editor such as the free Audacity:


A basic technique is covered here:


What format are your video files being recorded in? The difficulty is going to be that the mono sound is incorporated into the audio layer of the video file, and extra sound would have to be added in as an overdub.

If you simply want to record straight onto left and right channels, you would need to get a y-splitter lead for the audio connection, so there is two connections available. This would record two identical channels, sound would come from left and right speakers instead of just one, but there would be no stereo "surround" effect.

The videos are being converted into MPEG2

All that programs like Audacity do to a mono signal when converting it to stereo is taking the original source material, doubling it and outputing the exact same signal through both the left and right channels. If this satisfies your needs by all means go ahead and use it.


Does the camera have both red and white audio outputs on your camera?

If so the solution is very simple...

You need to buy a cable that has all 3 colour connectors on it: yellow, white and red. (the cheap ones are less then $5 if you don't care about the quality)

You cannot by definition convert a mono sound to stereo, what in essence you would be doing is creating a pseudu effect were the exact same sound waves would be emitted from each of the two speaker, but in no way is it stereophonic reproduction.

Is all that we see or seem, but a dream within a dream ?
