python - Read output from raspberry pi GPIOs connected to an I2S microphone chip

Question

I have a Pi Zero W with an I2S Microphone already properly connected - I know so because I can record sound just fine with arecord.

What I need to do is to use the output of the microphone to trigger a recording at a certain sound level. Any idea of how to accomplish this? I am assuming that there is a constant flow of data coming from the mic into the GPIO pins. Am I wrong there? If I can just see the output somehow then I can create the trigger myself, I just have no idea how to access it.

I am using the gpiozero python package.

Thanks!
