    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

    Hello,

    Take a couple of soundcards in a pc and a multi track recording program.
    This works best on a linux PC with the 64 studio distribution.
    You can use programs like rosegarden or adour.

    Greetings,
    Bertus
