    fft / ifft implementation

    Dear, I have decided to use dspic 30f4012 with 48k rom and 2k ram for implementing fft/ifft. My aim is to sample the incoming voice from a mic to the adc module for 5sec and then perform fft. I also wanted to inverse the process to play back the voice, just to check the process. So please help...
