Record audio Line-In when sound detect - request

Mon May 13, 2019 6:54 pm

Good evening,
I apologize for my English, I have a RaspBerry PI 3 + and I should record the audio from the microphone / line-in when I detect a sound, save it, analyze it with SoX and then perform some functions.
The problem is that I can't start automatic recording, I tried to use pyaudio, but it always returns error overflow.
Can someone help me?

Thank you

The Raspberry Pi does not have microphone / line-in input !

To have microphone input you would need to add something like a USB soundcard module.
