Posted 10/27/2016 on Sound Innovation

Involved in innovative 360 audio R&D, ARKAMYS built its own ambisonic microphone.

This is made of 4 STM digital Mems omnidirectional microphones.

You also need: the STM32 NUCLEOS development board, the ST CCA02M1 extension board and 4 additional ST MP34DT01 microphones.

When the STM32 board is connected to your PC, you can use it as a standard – 4 channels input – sound card.

These Mems microphones allow a very compact packaging. Thus, the 4 capsules can be very closed – as it recommended for the ambisonic recordings.

The next steps are :

  • Creating a mechanical design to have the ST microphone on a sphere,
  • Running in lab acoustical measurement of the mechanical design including the 4 microphones,
  • Developping a dedicated software to transform the 4 microphones RAW data into ambisonic B-FORMAT data.

 

Stay tuned to the next episodes!
