Getting mono audio to stereo

I have a clip that has a mono track, left channel only. The audio was recorded from the XLR1 channel on a DVX-100B. I want to make this stereo so the same audio can be heard in the right channel but I'm not having any luck.

When I click on the clip in the project panel, and then go to Clip->Audio Options->Source Channel Mappings, I can preview it in the dialogue box preview and hear that it is splitting the mono track into 2, it's stereo.

However, when I add the clip to the timeline, it's still a mono track. Any ideas? if you have a DVX, how are you getting stereo sound when recording with a wireless lapel mic into a single XLR channel?
 
OK, I figured it out. You have to extract the audio from the clip in the project panel. Then add the extracted mono channel to the timeline twice, to Audio 1 & 2, and then pan the channels left and right.
 
Actually that is a round-about way of doing it... there is a filter in the stereo audio effects bin called "fill left" or "fill right", just drop that onto your mono clip and it will be stereo!!! Voila

You can not drop a Stereo Effect on to an Audio Track.


Select the clip in the Project Bin then try Audio Options >Remap (from the menu)
 
I copied my mono track too and then from the Audio Mixer I adjust one track to the left and one track to the right.


I could not drop Audio Effects on a mono track mp3 but I had a stereo mp3 track and I could drop Audio Effects on that track.
Also after I exported my two tracks I was able to bring it back into Pro CS3 as a single stereo track wav and from there I could again drop audio effects on it in the timeline.

No, listen to what i am saying.... go into the bin audio effects, stereo... in that bin there are effects called "fill right" and "fill left" they will double the mono audio channel... i can not explain it any simpler!

Remapping is applied only to output formats... and changing it will end up screwing up your whole project!
 
Future man - you are wrong on all points. (Have you even tried what you suggest?)

Facts:

You can not apply a Stereo Effect such as Fill Left/Right to a Mono Track. There is no track to fill to obviously.

Re mapping is not applied to output formats - what does that even mean?

Two Mono Tracks are not Stereo.


Fact is if you select a Mono Clip in the Project Bin and then use Audio Mapping Option it becomes a Stereo Track in the Timeline.
 
FutureMan is correct... I do it all the time on non-stero projects.

By accessing the effects bin, under audio effects, stereo, you can drag and drop the missing channel (either Left or Right) down to the video clip on the time line. This simply fills the missing track with a duplicate of the original... making the sound full on both audio tracks.

This is not for true stereo mixdowns... there are other options for mixing stereo or surround-sound projects.

Indeed, futureman is correct. I do it all the time. That's the quickest way to get channel 1 or 2 audio to fill up both left and right tracks. It's basically a duplicate of one to fill the other so you have sound on both sides of your speakers.
 
You guys are confusing 'Mono' Tracks in Premiere with 'Stereo' Tracks with only one channel eg L or R. (a one channel Stereo track is not a MONO track as far as Premiere is concerned.)

(The Mono Tracks show 1 speaker Icon , the Stereo Tracks show 2 Speaker icon.)

The reason that the Effects are listed in Premiere as Mono , Stereo or 5.1 is that you can not use the effect from one type on the other. They are specific to the Premiere audio track type and Premiere will not allow a Stereo Effect on a MONO Track.

In the case of a Stereo track with only one channel...indeed using Fill Left or Fill Right works because it is a Stereo Effect on a Stereo Channel.

In the case of the O.P and his clip shot on a DVX100...it is most likely he had a Stereo Clip with one channel. Not a Mono rack as he stated.
