Naw, I am glad I asked.
A bit more into the project at hand:
There were two camera operators, myself, and Mia in the studio at the same time. Using a condenser mic for this situation, would have made it difficult to really capture her performance, without all of the noises in the control room (my largest room, that worked best for capturing the video). She has not yet controlled her esses so well yet, and the fact that a pop filter was out of the question, in order to see her pretty face, I opted for the 7b as a compromise for the situation at hand. It seemed to work well.
As far as the backing track is concerned, I agree that the I could tweak the verb a bit to help mix the live vocal with the backing track. I did cut frequencies at some points, to make room for the vocal track. This particular backing track was purchased from a site that gave a choice of which parts of the original tracks you would like to use. We chose to download none of the original vocals/backing vocals. The biggest issue I think, with the overall sound of the backing track, is that you get an MP3, and not a good quality one, of the tracks. Even then, they do not even seem to be the 'real' tracks from the original recording. Not sure where they come up with all this stuff anyway...
The fact that this is an audition recording, for a show called 'The Voice', it is not a possibility to fake the performance. It cannot be a lip sync type of thing.
There is another song we are using for the audition tape, but I personally can't stand the song. 'The Climb' by Miley Cyrus. Yuck!
Here. Watch at risk of getting this stuck in your head for eternity....
