The music is pop/ballad style, and the choir approx 40 people. I will only have one session to make the recording, so there is no opportunity for me to trial different methods.
From reading around the subject, I am intending to use several spaced mics as close to the choir as possible (using cardioid SDCs), and play the backing track on a monitor speaker behind the conductor i.e. trying to use the quietest point of the cardioid pattern mic pick up.
But I have been thinking whether it would help to "simplify" the sound signal which I am trying to cancel out by -
- - playing the backing track through a single speaker in mono
- altering the mix balance to emphasise drums, bass and synth/pad, and turning down or off any other instruments which are not needed for the choir to stay in time and in tune
- removing any added reverb
- using EQ to cutting off the highest (and maybe also the lowest) frequencies
Does anyone have experience of this technique overall, and do you think these additional measures will make any difference at all?
