 E32 Eigenmike® microphone array
The Eigenmike® microphone array is a patent-pending unique scalable microphone array with elements embedded into a rigid sphere. Individual microphone outputs are processed with a novel beamforming algorithm which enables the ability to record and playback accurate 3D spatial audio.
The Eigenmike® microphone array's directivity pattern can be controlled in real-time or stored and processed at a later time. Eigenmike® array technology is based on the principles of spherical harmonic decomposition. Some key characteristics include:
 infinite control of directivity pattern (shape and direction)
any number of unique beamformer outputs
electronically steerable
complete spatial description of the 3D sound-field
post sound-field processing of prerecorded eigenbeam signals
scalable in size and number of elements
uses extremely low-noise, wide-band professional electret microphone capsules
microphone preamp programmable gain and 24-bit, 44.1 kHz A/D conversion
done inside the spherical array baffle (other sampling rates are available)
single CAT5 cable powers E32, carries all digital microphone data,
controls the microphone PGA settings, and reports microphone status.
EMIB interface box converts E32 digital stream to standard Firewire
ASIO drivers supplied: E32 appears as a standard 32-channel sound card
We are currently shipping E32 arrays with spatial hamonic orders up to and including third-order. Please contact us if you are interested in purchasing a production E32 Eigenmike® microphone array.
