1 If your incoming audio is a simple tone, you can use the magnitude of your audio signal as a measure of loudness; if you have a more complex sounds composed of multiple frequencies, you'll need to perform a FFT first to extract the component waveforms. From there, pick your preferred frequency and use that. For a PWM, you have two options.

In VHDL everything is kept multiplied by 1048576, but after an input is multiplied with a coefficient, the result is shifted 20 places, which is the same as dividing by 1048576. The end result is a working biquad filter, the full implementation can be found here. A lot of biquad filters And done, right. Biquad works, filters can be added.

Phase 1 -- get the mic input to work at all. Phase 2 -- develop DSP algorithm for FPGA. Phase 3 -- implement and test. One thing you can try is getting the mic input into a file that you can use for testing DSP algorithms out. It is better to test out DSP on a computer first as the iteration time is much lower.
