    Hi. am a final year student of electronics engineering. am doing a project on voice encryption in pstn network. am thinking of incorporating ADC & DAC together with the PICs. The ADC for converting analog voice to digital domain so that it cab be processed(encrypted) with the PIC then converted back to analog by DAC. This is at the microphone part, at the speaker reverse process will be done. the problem is that the idea is to theoretical, i dont have clear technical details on how i will do it. anybody with idea(s) please.
