At the moment, for a project i want to build a combination of the MK171, a voice recorder used during a conversation at distance. The idea is that one can talk at distance, like a simple telephone connection. Only without dial tone. While having this conversation one can change the pitch, with the use of the MK171. Likewise, when no one is at the other side of the line, it is possible to record your one voice and play it back, like when using a voice recorder.
I want to make one circuit of this, the question is how? How can i connect these circuits? Where do the different components fit in, in such a way this will work?
P.S. If i start the MK171 i want it to start without transformation, is this possible???
Thanks!!
