interview audio, wired lav vs boom

Boom sounds better than lav. In some situations, I use both and mix some boom with the lav. to give some room presence to the track.

What is the process of mixing a lav with a boom..?
I was told that due to things like the distance of the mic's to the mouth etc there are sync/phase issues... but i'm sure there is more to it than that... How do you work with that??


cheers
 
I think you would get phase issues if both mics were mixed to the same level. If your lav is the main mic, and the boom mic is only used to fatten up the ambiance, the phase issue is moot because ambient reflections are already delayed time-wise, as they have bounced off the walls, and they would be mixed lower and act like a reverb plug-in effect - therefore not competing for dominance with the lav.

In other words, don't worry about it.
 
You'd have to turn it down pretty low to minimize the phasing effect as chadfish mentioned. Unless you intentionally set out to get this effect - then you'd probably set the boom mic much father back in the room (hence, a room mic).

At that point wouldn't it just be easier (with more control) to just add a little reverb ambience.
 
If you have to choose- Boom mic definitely.
If it's a noisy situation though, I would use the lav.

In just about any audio editing program (other than FCP audio editing) you can slide one track in increments less than 1 frame to match the sync perfectly.

Another technique, if you can monitor the mix summed to mono on the set, is to adjust the boom/ lav mic distance and placement till it sounds right.
