I have a dvd recorded in mono. Is it possible to convert to sterio using vs9. If so, the process. Can I request all those who have helped me along from a novice status to guide me. Thank you for your grace of helping out.

Hi

If it is true ¡¥Mono¡¦ and not just the second track muted.

Start a new project.
Insert the video clip, the project properties should change to match the clip properties.

Now change the project properties to show Stereo
Render the video using 'Same As Project Properties'

In addition to Trevor's approach, you can also try this.

Assuming you have a track that only has one channel (left or right), and you want to duplicate it to the other "side"

Import the item (if part of a video, then rt-click/split audio). Then click on the audio track, click on Audio View, then the Attribute Tab, then select the option to Duplicate Audio Channel (click on the radio button for the left or right side).

NOTE: you don't have to split the audio if you don't want to...

Regards,
George

What do you mean by "mono", and what is the encoding format (LPCM?, Dolby AC3?)

If the sound is coming out of both speakers (as a proper mono recording should), there is no advantage to simply converting it to "stereo", because this will simply create two identical left & right tracks.

There are ways to simulate stereo. The simplest way is to use an equalizer to boost some frequency bands while cutting other frequency bands, then setting opposite-complimentary settings in the opposite channel.

AFAIK Video Studio does not have an audio equalizer filter... But, I'm not sure... I almost always use a 3rd-party audio editor. I happen to use GoldWave (~ $50 USD), but Audacity (FREE!!!) should be able to do it too.

To expand on Doug's advice, you can also install audio filter plug-ins to VS, many of which have EQ. Free ones can be found here.

THANKS Trevor,George,Doug and Black lab,
for the guidance.Much appreciated.
OOPS! Doug caught me napping. Yes.Mono could be heard from 2 speakers. What I meant was, I could only hear sound from 1 speaker.
I will try all the said methods and report back.
