I agree to me it would be very useful to have code for mems mic readout. If someone is doing prioritization of todo list I'd vote for that :) thanks

Thanks for reply. I appreciate your effort to make it all working, great job! At some point I managed to make the adafruit mems i2s mic work on Rpi so...

Yes you're right that it'd be best to have at least A weighted SPL values and even better some sort of FFT graph.Another way that people look at noise are...

Regarding obtaining the A-Weighted SPL I have found this example: https://docs.smartcitizen.me/Components/Urban%20Sensor%20Board/Noise%20Sensor/ and here are some interesting Github repos related to it: 1. https://github.com/fablabbcn/smartcitizen-kit-audio 2. https://github.com/oscgonfer/AudioI2S

I have found another implementation here, so it might be helpful to see how it was done on other platform : https://github.com/Tinkerforge/sound-pressure-level-bricklet/ https://www.tinkerforge.com/en/doc/Hardware/Bricklets/Sound_Pressure_Level.html

Hi, I have found another piece of code that might help with getting the fft noise levels: https://github.com/colin-guyon/rpi-audio-levels Sorry for flooding this topic with bunch of links, I'm not a...

I also have similar issue. Readings show 'nan' for all the sensors

Thank you for the info, hopefully they'll resolve it soon. > They gave me a drive link to a new image. I tried it on a Pi Zero and it...
