Directional microphones are further broken down in the categories cardioid, super-cardioid, hyper-cardioid, and figure-eight. Cardiod directional microphones favor sounds directly in front of the microphone while rejecting sounds that are off the main axis, while figure-eight (or dipole) reject sounds at 90 degrees to the main axis.
