Polarity pattern:
Cardioid
Cardioid microphones are unidirectional microphones with
a cardioid polar pattern, which means a higher sensitivity to
sounds coming from the front and, on the contrary, a minimum
sensitivity to sounds coming from the rear, where a gradual
attenuation takes place.
This heart shape is obtained by leaving the diaphragm free
at the front and building acoustic labyrinths at the back.
Cardiod microphones offer the best frequency response at mid frequencies. The bass is more dispersed,
while the high frequencies become more directional.
As the cardioid mic can reach a preferred angle of 181°, they are ideal for general sound pick-up from a
frontal point of view. In addition, cardioid mics support spaced sources, unlike two-way mics.
One thing to note about cardioid mics, however, is that feedback can occur if there is a rear-firing
loudspeaker.
Cardioid polarity pattern is recommended for use in podcasting, streaming, voice recording, etc.
