Hello together,

i new for using the XMOS solutions. I need a VocalFusion kit with very good microphones, only beamforming und usb.

I know that the VocalFusion 4-Mic have very good microphones instead of the VocalFusion 7-Mic but wich solution do I need for the quickest solution to get USB and only Beamforming into the microphone solution?

I would be glad for an answer.


Best Regards,

Daniel

Hello Daniel
Three xCORE VocalFusion Kits for Smart Microphone development are available:
xCORE VocalFusion™ 4-Mic Kit for AVS
xCORE VocalFusion™ Speaker: Circular [USB | I2S]
xCORE VocalFusion™ Speaker: Linear [USB | I2S]

The all have very similar performance.
The key question is: What topology is required?

If the VUI is located on a wall, it covers a 180 degree range.
In this case you would use a linear array.

Otherwise use the circular microphone array which covers a 360 degree range.

Note also: Even though the Circular Array HW has 7 microphones on it, only four of them are used.
See the board support page for more information: https://www.xmos.com/support/boards-selector
The Product Brief is usually a good start.

Hello Thomas,

thanks for responge, I do not get an E-Mail that you have answerd.

I have a requirement that it works in a room with 3 secound reverberation time.

I bought the xCORE VocalFusion™ 4-Mic Kit for AVS for the first hardware setup I see that my linux system do not recognize the xCORE VocalFusion™ 4-Mic Kit for AVS as an microphone but I need that to do some acoustic tests.


Best Regards

Daniel
