Can you make a game that picks up simple mic-inputs from the player?

Right so I'm an indie game developer, working primarily in the renpy engine. I am as new as one is when it comes to coding, so excuse me if I sound dumb, but I had an idea for a horror game that would read whether or not the person playing was making any noise or playing completely silently and then react accordingly. Is this even possible or is it just way too complicated? Thanks in advance and sorry if this is a dumb question :)

Definitely possible. Look into any audio library that will perform a Fourier transform on audio. (It might be called FFT for Fast Fourier transform). 

This will get you your audio (i.e. the mic) represented in the frequency domain, or rather, as what the various magnitudes of the various frequencies are that make up the sound wave.

You can run logic over those magnitudes to say stuff like "if the magnitude of any frequencies in the high pitched range spikes for a certain amount of time, then the user may have just screamed"
