When is it advantageous to use Omni-directional mics?
When you are recording in a venue that has good acoustics, the audience is fairly quiet and you are fairly close to the sound source, Omni-directional mics are capable of make excellent recordings and would be the mic of choice. Omni mics also are more forgiving of handling noise and wind noise, so are a good choice if you can’t secure your mics firmly or have to record in windy situations and don’t want to use large windscreens.
