特性
- Beamforming: To emphasize the sound from the target direction. This can be achieved with two inexpensive omnidirectional microphones.
- Noise suppressor: To suppress ambient noise. Maximum noise reduction is 22dB. The amount of reduction is automatically adjusted for each frequency band according to the frequency characteristics of the input noise so that audio distortion is reduced.
