The producers of the RadioLab podcast episodes, "Darkode" and "Ceremony," implemented several elements in order to make the material more interesting and engaging.  First of all, the introductions did a good job grabbing the attention of the audience, with unique sound editing techniques.  Furthermore, the producers continued to add immersive sound effects throughout the duration of each podcast.  In the "Ceremony" episode, I really liked how they added amplified computer processor noises to imitate what it would be like to listen through the high-tech microphones that they were worried hackers might be using in the next room.  This made it clear just what these microphones were capable of and the extent that hackers sometimes go to.  I never knew such technology existed, and I would have thought it was ridiculous to worry about someone listening to the sounds your computer makes from another room.  Hearing how it is possible made me realize that sometimes being paranoid is justified.  There were also a variety of other sound effects that made the audience feel like they were part of the experience.

Another aspect that made the podcasts more interesting was that they told stories.  In the "Darkode" episode, they got a victim who was hacked using Cryptowall to give a firsthand account of what happened to her.  Her story helped make it easier to understand how Botnets work and how hackers can use them to infiltrate millions of people, encrypt their data, and make them pay ransom to get it back.  In the second half of the episode, they got one of the original creators of Darkode to explain its backstory and how it worked.  His account gave an interesting perspective on its original intended use, and how people twisted it to serve other purposes.  Personally, I found this content fascinating, and the way it was presented made it even more engaging.
