I'm an absolute beginner. I'm doing a project that involves estimating the time delays between the sound signal arriving at different microphones in an array (the project is a bit complicated but I'll find my way through). I'm planning to use a panda board and connect the microphone array to it. But before going about implementing the array, I thought I should first learn how to do some DSP on an analog input. Basically, how would I connect ONE microphone to the panda board and do, for eg, an FFT on the signal?
The panda board has an audio in port but that wouldn't help much when I have to use multiple microphones. Can I connect the condenser mic (the really cheap one ) using 2 wires to a general input pin? How would I read input from it? Will I be able to record sound using such a setup? And I understand that I have to do the Analog to digital conversion (In fact I WANT to do it by myself, so that I would better understand how stuff work).
And now the million dollar question : If I connect a few more microphones to different input pins of the panda board and give them the same sampling rate (I have no idea how but I'll learn it) will that make a microphone array?
