This unique integrated array microphone system is designed for use with Andrea’s patented beam forming and digital noise reduction audio software, providing “The Freedom of Voice”.

System Overview

Earphone Bass Expansion
SuperBeam headsets employ powerful neodymium magnets in the speaker transducers providing a wide frequency Response of 20Hz - 20Khz. The headset also features a unique bass - reflex ported earphone housing design for producing deep rich base, complementing transducer output efficiently of clear - mid-range - and sparking highs.

DSDA Patented Adaptive Beam Forming
The DSDA algorithm powers Andrea's SuperBeam array microphone system, enabling "Boom Free" performance. The array microphone system forms an audio pickup beam toward the users mouth and eliminates background noises that are outside of the beam.

PureAudio Award Winning Noise
Reduces repetitive background acoustic and electronic system noise utilized on microphone input and received audio playback. Increases the sound quality of your VoIP calls on applications such as Skype.

Binaural 3D Surround Sound Recording
Great for recording live entertainment, music, lectures and even environmental sound samples. SuperBeam microphones are placed in close proximity to the user's left and right ears, establishing a "Real Head Transfer Function" acoustic effect. Sound arriving at each microphone is in natural phase and duplicates real ear sound capture. Headphone playback then delivers a virtual 3D surround sound experience, reproducing one's listening experience.
