The directional sensitivity of a microphone, indicating how it captures sound from different angles. Common patterns include omnidirectional (equal pickup from all directions), unidirectional or cardioid (focused on one direction), bidirectional (pickup from two opposite directions), and supercardioid or hypercardioid (narrower focus with some rear pickup). This attribute helps users choose a microphone that best suits their recording environment, whether they need wide coverage for group discus

The electrical impedance presented by a microphone input, expressed in ohms (Ω). It indicates the resistance that the input circuit offers to alternating current signals, affecting signal level and compatibility with microphones.

The total count of microphones integrated into a device. This value indicates how many separate audio input channels are available for recording or voice‑recognition functions.
