The Voxcoder was one of the most interesting things I have ever heard of. The origin of the machine, being just a voice changer/imitator, really made me wonder what the creator had in mind when he made the machine. Being able to replicate a human or animal voice opens up so many pathways such as deception, manipulation, and somewhat discretion. I was extremely surprised when the machine was able to replicate the cow noise almost perfectly. It is also kind of scary considering that a machine can produce convincing human and animal noises. All I could imagine was hearing a a series of growls while walking through the house. After the Voxcoder was evolved into the Sigsaly the organization and complexity of the system used for conferences was baffling. There were so many steps to a single conference that it was sometimes hard to keep up with what part of the process the podcast was explaining. I think its cool but also limited that the conferences functioned by mixing and masking human voices with random noise. Its an incredible feat but if the Germans were able to figure out what was happening and develop a method of decoding it, the Allies would be screwed. It would be a more incredible feat if the Allies were able to completely scramble and distort the messages without having to mask it behind random noise.
