i m doing my fyp in audio tracking of sound emitting source.(Low frequency)
I m performing Time difference method in matlab.
In this method i have to 4 mic's to be use at same time on same computer simultaneously.
I m able to use 2 mic's on same computer at same time using Y connector.
If you know about any card which perform the intended task easily then please inform about the link which contain help about that product.
Plus if any other feasible solution u know please share.
Looking forward for help.
 

I am not sure I understand correctly, but I would use a 4-input mixer. Or on the cheap side I'd join all microphone "hot" wires preceded each with a 10 kOhm resistor - as I do to merge outputs, e.g. many computers, into one single amp.
