let say i talking to a mic (input analog sigal), how to convert the signal into digital signal and can this digital signal play in computer? is it needs a special ADC to cenvert audio from analog to digital?
Firstly a mic has a tiny output too small for connecting to an ADC you need a pre-amp to get it to reasonable sampling level.. then you need a DSP processor that can sample up to 44khz (at least)
You can buy these from electronic shops for relatively small money ..
But why!! virtally every computer has a mic port and software built in.. Do you need to process the sound in some way?
