  • how to assign one audio track to be Left and Right channel?

    Posted by Elizabeth Thai on January 13, 2012 at 7:28 pm

    Hi All,
    I recorded a bunch of interviews and some of the audio only plays back in one of my earphones, either left or right. I want to duplicate the the audio track, and then assign one copy of it as the left audio channel and one copy as the right audio channel for a more robust sound. Can someone please tell me how I can do that?

    Thanks!

    Yep, been doing this for the previous 24 hours.

    Ok, right click on the audio event go down to the Channels section and you can pick-off what you want:

    Left
    Right
    Combine
    Swap

    Much to choose there.

    Then there’s the Pan Envelop!

    Have fun,

    Grazie

    [Elizabeth Thai] “I want to duplicate the the audio track, and then assign one copy of it as the left audio channel and one copy as the right audio channel for a more robust sound.”

    Actually, you don’t want to do that because you run the risk of phase problems if one of the tracks gets nudged out of sync. Duplicating the mono track will only make it louder, which you could easily accomplish by raising the volume fader.

    Since your source was mono, make the channel mono in Vegas by using the operation Graham described (i.e., right-click the audio event and select Channels | Left or Channels | Right depending on which channel has the audio). If you want to make it more “robust” add some appropriate amount of EQ.

    I have done something like this to add some “dimension” to a mono recording of a conversational interview. I used the pan envelope to position the audio left or right by 5%. It’s subtle, but believable. Any more pan and it would sound very artificial or amateurish.

    I also do this routinely when editing theater or stage performances. When the talent are all miked, it sounds fake when the actor walks across the stage and the sound comes exclusively from the center speaker. Again, no more than 5% pan or it comes across as exaggerated.

    I’ll just ask the question because I don’t know. Would tools-scripting-stereo to mono work in this case? It’s not an area that I use often, but I had a client bring in some tapes for transfer that were recorded in mono and that’s what I did to get the audio out of both sides. Thanks for answering, Dan

    [Dan Thompson] “I’ll just ask the question because I don’t know. Would tools-scripting-stereo to mono work in this case?”

    That script would split both channels into separate tracks and it is useful when you record into two channels. Since the Elizabeth only recorded one channel, that script isn’t needed because you’d just be deleting the second track because it has no audio on it. So the script is overkill for this particular case.

    Hi everyone,
    thank you so much for your comments!

    I started to do what I had posted above, separate the tracks, put one as “left channel” and one as “right channel”. The audio showed up on one of the tracks and the other track was just a blank line. I right clicked on the blank track and clicked “swap” and it duplicated the track. For the most part it just sounded louder but I think it sounded a little fuller.

    After doing this for a while I started to play with the other buttons and found that if I pushed “combine” on a track, it would turn the mono track into a stereo track so I went back and undid what I’d done and decided to use the “combine” feature instead. It was a lot faster for me to do it this way. So for every take with dialogue, I have two audio tracks, they are duplicates of each other, and both of them have “combine” selected as their channel. The sound seemed the same to me as when I was doing it the other way.

    Can someone please tell me if this is a good way to deal with the situation? What I’m looking for is a track that is stereo, with a slighty fuller sound then the mono track by itself.

    Thank you so much!

    No it’s not. You recorded one channel (Left) and so you should set your audio to use only the Left channel. If you want it louder, use Normalize or increase the volume. Duplicating the track only makes it louder. Combining the channel could give you phase problems. Just use the left channel.

    Hi John,
    thanks for responding. I’m not sure I understand completely what you’re saying. If I select only the left channel, won’t the audio only come out of the left side? My goal is to have the sound come from both the left and right side.

    Thanks!

    Selecting left only or right only means that channel now becomes mono which means that it comes out of both channels at the same volume.
