I’m about to finish my master thesis in Telecommunication Engineering at University of Alcalá. It involves microphone array modular system development as a research tool. Each module is composed of Raspberry plus MATRIX. The challenge has been dealing with FPGA code to synk audio adquisition of different modules. Physical connections have been added to share signals between them. In order to handle the machine, python library is programmed.
I will upload the document when it is done (sorry it is written in spanish, but it will be a pleasure for me to translate whatever you want). I would like to start a discussion about it soon.
Thanks for making MATRIX Creator. It is amazing.
