Cardioid focuses the front
Cardioid microphones are common for solo voice because they focus on the speaker and reject more sound from behind the mic.
Omnidirectional hears all around
Omnidirectional microphones are useful when the microphone is clipped close to a person or needs consistent pickup as the speaker moves.
For podcasting
Use cardioid for most podcast desks. It gives the clearest path to focused voice capture.
For lavaliers
Omnidirectional lavaliers can work well because they sit close to the speaker and do not require precise aiming.
