Almost every Internet broadcaster uses Skype to connect with guests for a show. Using Skype can be frustrating because it is a half-duplex service, meaning that only one person can talk at a time. If the host and the guest talk at the same time, the louder of the two is going to cause the other person’s audio to duck or decrease in volume. Ducking can be a real problem when the show is about a hot topic and the host and the caller are really motivated. It is also a problem if the host tries to play music or send return telephone audio to the guest.
There is a simple solution to prevent Skype from ducking calls. When you hear it, you’ll wonder why you didn’t think of it already. In professional broadcasting, the on-air talent on a remote broadcast almost always has return audio from the producer or the control room back at the studio. Notice how even the weather guy on your TV station has an ear piece so that he can receive his audio cues from the director.
