InSight Acoustics is the developer of HyperMic technology, based on optical and acoustic sensors combined into a single, optically guided acoustic beam-forming device. HyperMic can optically track multiple people or any user-selected sound source, estimate a relative direction to each source, and concurrently steer independent acoustic beam formers. The output of each acoustic beam former is a digital audio stream whose audio content is predominantly composed of sounds arriving from the direction of the selected source. An extended version of the HyperMic technology, CrossBeam, utilizes two or more synchronized HyperMic modules in order to direct multiple beam formers from different directions toward the same sound source. CrossBeam digital audio stream outputs are time-aligned and cross-correlated to provide an additional speech-capture performance boost.
