Hi,
How can I take the ADC of an input signal given to the microphone input of a windows machine? Is there any program or library to do so?

 

hi 1995,
This might do what your asking, I use it for creating plots, it can save audio mike/line input files in different formats.

You can start with a PC sound card based scope for free. Will give you basically
audio range scope, spectrum analyzer, and function generator all using your
PC sound card.

But first build a simple circuit to protect sound card inputs so you do not
ruin from transients, overvoltage. Google "protect sound card input".

Thanks. I have already used this. But I want to do it in a c/c++ program and not using a dedicated software as I have to perform some algorithms on it

I am looking for a C/C++ program or a library to monitor the microphone input and store the ADC values in a buffer. I do not want to use any other software or circuit. Just like how we can take ADC on Arm microcontroller, I want to know how to do the same on my PC.

Seems to be a good library..

Can it be used on windows 10? And can it record audio input whenever there is a speech event and store the values in a buffer? I want to take FFT of this buffer later

No Idea! download and try it... Its free..
