The GAVEL™ by Kardome is an 8-microphone array designed  for applications such as voice user interface (VUI), acoustic surveillance, acoustic radar, hearing aids research, conference calls and sound fields analysis.

 

8 synchronous omnidirectional high-performance microphones are arranged on a surface of a circular board with radius 90 mm. 6 microphones are equispaced on the perimeter, and 2 at the center.

 

The deployment of the 8 microphones is suitable for a range of array processing algorithms including beamforming, interferometry, source localization, space-time adaptive processing (STAP), NULL steering and matched-filed processing (MFP).

 

A dedicated SW library is provided, which includes a convenient API for the USB communication and for embedded processing of the microphones signals. This library can be naturally integrated into your C code for the ADSP-SC589.
