| I don't think so ...
I don't want to make an analog encryption. I want digital...so I have to code a digital signal. Let's say that I convert an analogue signal from external mic to digital, I Xor the signal with some noise , and then I convert it back to analogue to send it via mic. phone input. It won't be good, because of the mic line bandwidith.
I don't like either the internal device sollution, I want some external device, but... it seems that I don't have a choice.Any other ideeas ? |
