A tricky problem, and I don't have an immediate answer to it. But I do have question. Are these miniature mics *really* directional, or do they become directional by being deployed in the way they were designed to be, e.g as you describe ? The reason I ask is because a) making a really small mic directional while preserving other required performance characteristics (e.g. sensitivity or self-noise) is not an easy thing given the physics, and b) when a mic is placed very close to any object having the size of a human head its polar pattern is likely to be modified by the presence of that object, at least at medium and high frequencies. -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
