Moving audio half a frame (or so)

Did a 2 camera cooking show with 3 hosts all mic up with 3 seperate lav mics. (2 mics going to one camera and 1 mic going to the other camera)
When I load them on the timeline, and line up the clapper board, the cam with the single mic is about a half frame off on the audio. This ends up cause a mild "echo" sound because it's off a little bit from the other 2 mics.
I think there is a way to move the audio at a smaller amount than 1 frame but can't for the life of me, figure out how????

Can someone point me in the right direction to line them up correctly? Something about changing the timeline from frames to milli seconds or something????
 
Set timeline to audio units. Little dropdown menu right top corner.
Now you can move the audio to 1/48000 of a second.
 
thanks here too. biggest tip I've learnt in years of using premiere pro. I use to always put up with audio being half a frame out.
 
Can anyone expand on this?
Ive change the timeline to measure in audio units, but can still only move my audio waveform by a frame at a time, or is that because it's attached to the video track?

Click to expand...

While I've only adjusted audio that is 'pure audio' in this way, I suspect you have to unlink the combined video+audio tracks of the camera media, to then 'adjust' the audio of such a combination.

I'd also mention that sound travels at about 1 foot per millisecond. At 24 fps, that's 41 feet... and depending on the cameras and where they are located, there could be a lag. This would perhaps only be problematic for a distant camera 'zoomed in', or for 'big motions' that have obvious sound components.
 
Thanx Mr.Clark, that clever bit of math makes me think I better go back and check my synch again :-)
