Two microphones spaced apart less than 25 mm provide information about the spatial situation of sound sources.

Even non-stationary noise can be efficiently reduced maintaining excellent voice quality, and different sound sources can be separated with “focus” on a wanted direction.


For different use cases we distinguish different microphone geometries with Lateral Focus, Frontal Focus, and Front and Rear in the top of a phone cabinet (follow the links to the demo videos).

Code is available for ARM Cortex NEON, Texas Instruments TMS320VC55x, CSR BlueCore5 / CSR8670. Further platforms on request.

Supported Operating Systems: Linux, Android, QNX, DSPBios; further OS's on request.
