Evaluation Kit for Microphone Array Beamforming

vicDIVA.

The vicDIVA evaluation kit allows you to test the beamforming algorithms of voice INTER connect. The algorithms of our vicPURE framework included in the kit can be configured for different applications. Speech enhancement through spatial filtering and noise reduction can be used to improve communication solutions or for voice assistants. The microphone array can be aligned at a speech source either manually or via automatic source localisation.
vicDIVA includes an 8-channel microphone array with status LEDs, the vicSBM hardware module for audio signal processing and a Raspberry Pi for application development. The processed and optimised speech signal is made available for use in applications via an ALSA interface on the Raspberry Pi with low latency. Voice quality can also be evaluated directly with connected headphones.
