I’m working on an application to record signal with frequencies from 21kHz to 24kHz. I have few questions:
Does Matrix Voice support 96KHz sampling rate? I have recorded signal using HAL code and the results seem to be aliased. If not, what is the maximum sampling rate that it supports?
Is the filter on FPGA core adjusted based on input sampling rate from HAL code? Should we make changes in the FPGA core if we want to support 21-24KHz?
Do you know the frequency response of microphones on Matrix voice? Do they support more than 21kHz? Datasheet does not cover this information, I was wondering if you have tested them.
I appreciate if you can help me with these questions.
