Implement a voice meter on FPGA

[macakolo]

Hail, we are looking for a way to implement an analogue anudio signal from a AD into a FPGA, and we need to detect the voice level / dB level of that audio?? Anyone has ecperience on this, who can guide us to the right direction / algorithm on this type of solution!!

Thank you!!

You can use audio ADC like UDA1361 (there are many chips like this) this chip has IIS digital output interface. It's very simple interface to realize in FPGA. Characteristics are normalize in working area therefore to calculate signal value will be not hard ( voice level / dB level ).
