When you think about the World War, there must be a scene or a voice in your mind that broadcasts the radio talks. The classic voice with electronic noises in the movies probably has made an impression. I didn’t know about the source of the noise before. I used to thought that the voices were not clear because of the lack of technology to communicate efficiently; but after the podcast, I learned that those noises were created for data encryption.

The podcast explained clearly how the machine works. The machine can break down a human voice into basic components; then transmit those basic components so that the receiver can recreate the voice on the other side. This invention was marvelous enough to create a new generation. For the first time, sounds can be digitized and transmitted over a long distance. What’s more, it also mixed noises with those components to make the encryption unbreakable. These two innovative ideas were combined together, led to the success of the war.

The producer used different soundtracks so that we can hear different people telling the whole story. This new approach creates a sense of warm and inspiring. We all have the terrible experience of losing focus after hearing a stable and unchanging sound for a long time. This podcast can easily catch the audience’s attention. It feels like having a conversation in front of a bonfire with several knowledgeable scholars. Besides, the producers also presented the original radio sound back to the time of war. When those clips were related to the sound people often hear in the movies, the audience can better understand the ways Voder are used. The lecture will not be complex and boring principle telling in this way, but be a vivid presentation.

After hearing this episode, I’m probably going to consider more about the audience for the podcast episode. Audiences’ interest is always the first thing to think about while making an episode.
