How to GIVE 12 AUDIO Inputs to Computer Simulataneously through Micro controller/PIC/FPGA

HI EVERY ONE
i m makin gy FINAL YEAR PROJECT
named as GUN FIRE DETECTION SYTEM or SPOT FINDER

well i have choosen a 25ft * 25 ft area, and place 12 MICs at distances...

well i throw any fire cracker for producing a sound/noice
so each mic can detect voice and send data to PIC/microcontroller,,
in PIC/MULTIPLEXER , data is MULTIPLEXED to 1 signal, and this signal GOES to PC via serail port or MIC input @ MATLAB or LABVIEW

in LAB VIEW/AMTLAB, 12 signal will be recieved after DE MULTI PLEXING

Now I have seperate the 4 signals having HIGHT VALUES, then i put ALGO, or calculate the distance or SPOT according to the sound intensity in EACH MIC!!!

now the PROBLEM i m facing is that how i send 12 audio signals simultaneously to COMPUTER????
either i use PIC or Multiplexer of DSP KIT or FPGA????

if any one had idea about it, then he must reply the post
i shall be thankfull to him

waiting
