Mono to Stereo

I'm new to Premiere and Audition and loving it although I'm stuck. I'm making a short film with narration. I shot the movie and the voice over was recorded on a separate voice recorder which is mono. I used Audition to extract the sound clips I needed to use in Premiere. I now notice that the sound has two tracks, L & R, but the sound is only on the Left and the Right is 'empty' How do I copy the left channel into the right, so it's the same sound in both?

I don't think the others read this quite correctly!

Ctrl-A to select the entire track, then Effects>Amplitude and Compression>Channel Mixer, and select the 'fill right with left' preset, apply it, save the results, and you're done.

I should also point out that this doesn't make it 'stereo' as such, just dual mono, which is rather different...

That was the second option suggested in my post above.

But as others have implied you shouldn't necessarily have to have a dual track mono signal to make the narration come out of both speakers. Surely that's what panning a mono track is for or doesn't Premiere do mono panning?

I have no idea. I was thinking of installing it to find out what the options are - I suspect that with many of the things that people think that they have to import into Audition to fix, they don't need to at all!

Waveform View>Edit>Convert sample type>Channels: Mono. ( The default bitrate of 24 is good, too.) The resultant mono file will play in either a mono or stereo track in Multitrack, no problem.

When you use Convert Sample Type/Channels/Mono click on the Advanced tab and set Left Mix 100%, Right Mix 0% to get all of the left channel and none of the right.

Also Effects/Amplitude and Compression/Channel Mixer/Fill Right with Left.

Or Edit/Extract Channels to Mono Files.

Or in Waveform view Toggle R channel off and select all of left channel and copy. Then toggle L Channel off and Paste copied audio into Right channel.

Interesting. Does that achieve something that a simple 'convert to mono' procedure doesn't?
