I’m trying to figure out how do the 8 microphones read data? Do they read data all at the same time or there is a lag between two mics?
The data from the mics is read by the FPGA and yes is read all at the same time. The small lag in time in the mics is mainly related to the distance between the mics and the different times it takes for the sound waves to get to the different microphones.
Hope this help, anything we can help with please share here.
A good demonstration of the delay using the MC with a direct comparision to Alexa Echo
compared to a standard mic
which turns out to be faster than the MC?!
