What is SuperDirectivity?
Don't worry if you never heard of SuperDirective beamforming because it's some of our latest technology from Retune.
Super-Directional beamforming allows signals from 2, 3 and even 4 microphones to be segregated according to the direction the sound, just like beamforming. The difference is it is much more powerful.
Consider a situation sketched below:
A headset with SuperDirectional beamforming will make the far end only hear clearly the target speech, and renders the disturbing speech complete inaudible to the far end speaker!
SuperDirectional beamforming works best with:
- Two or more microphones in a fixed geometry
- The target talker is in a fixed angle (geometry) relative to the array.
- Disturbing talker and noise signals arrive from a direction as different as possible from the talker.
- Target talker in end-fire direction relative to at least two microphones.
SuperDirectivity is only available from Retune DSP.
