Sample code for using the microphone via I2S on a ESP-EYE board

Hello Daniel- This is a great contribution. I was just looking for example code to use the ESP32-EYE microphone and your blog post nailed that. In the blog post itself, your code shows a sample rate of 40000. At that rate, the web browser bands would be correct as labelled. However, on the github site, the code is written for a sample rate of 10000. At that lower rate, all the labels for the bands must be divided by 4- i.e. each bin is 10000/512 or 19.53 Hz. So the bins from 200 up are 200 X 19.53 or 3906 Hz, not 16K (which is not possible to sample at a 10000 Hz rate - Nyquist)
Many thanks
