Change audio input to COM in Python

[priscilla v]

Greetings, I need help and the guidance of some wise :), I need to change the reading of the signal and that instead of the audio input that is the USB COM in this program that I attach, how could I achieve it?

@priscilla-v not without more electronics.

The Line in is analog, while the COM port is digital. So you would need an external ADC, e.g. a microcontroller to convert the signal.

@aha_1980 But what I need is to analyze analog and non-digital data through the serial port...

As said, you need some electronic circuit to convert the data from analog to digital then. The soundcards line input is such a circuit...
