Hello,
You see I have to do a project with a raspberry in which it consists of using the raspberry and a microphone to convert it into a sound meter and export the decibels to a database.
The problem I have is that my knowledge about python is null.
It would be very helpful if you could give me a sample of how it is done.
Thanks in advance.

Hey! You can use PyAudio (or sounddevice) to capture audio, compute RMS (root mean square) to get amplitude, convert to decibels (e.g. 20 * log10(rms)) and then push the result into a database (e.g. SQLite, MySQL).
If you tell me which mic setup / OS you’re using (Raspberry Pi, USB mic, etc.),
You can also try this tool for free. link removed
