What is the difference between cardioid, hypercardioid, and supercardioid patterns?
Cardioids have a heart-shaped polar pattern at most frequencies, but they tend to be more omnidirectional at low frequencies. Hypercardioids are less wide compared to cardioids, but still have some omni characteristics at lower frequencies. Supercardioids are similar to hypercardioids at high frequencies, but they act more even at low frequencies by creating a deeper rejection point at around 125° off axis.
