iZotope ANR-B brings Adaptive Noise Reduction to The Christian Broadcast Network's 700 Club Interactive. The popular ABC Family TV show uses ANR-B to increase caller intelligibility.

ANR-B on the rack at CBN's studio
Airing live conversations from around the country, 700 Club Interactive depends on people communicating with the hosts by phone, Skype, and satellite.
Until recently, these interactions were with other studios, but there was a growing need to do more Skype and phone feeds. Once calls were coming in from outside of a controlled environment, the situation presented a unique set of challenges. The callers' audio was integral to the program, but the signal quality would vary wildly. Phone interviews became especially tricky since the hosts would need to interject their comments, making line noise variable between each feed.
Phil Peters (Director of Audio, Broadcast Operations for The Christian Broadcast Network) saw a demo of iZotope's ANR-B at the NAB tradeshow and knew he had found what the show needed. "It gave us encouragement that we could make the audio much better automatically," explained Peters. "As soon as we inserted ANR-B into the signal chain, all the mixers noticed a big difference with the in-bound audio. The noise floor was much lower and perceived intelligibility was greater. The best thing is that the mixers don't have to do anything as the show moves from one in-bound source to another. The unit just adapts and improves our audio automatically."
Using ANR-B, the show is able to do two-way interviews across up to five remote locations simultaneously. When ANR-B is placed on the audio sub-group that handles all the incoming feeds, they have found the incoming audio to be much cleaner, more easily understood, and more on par with the studio microphones' quality. Peters went on to say, "We have another hardware solution available to us for broadband noise, but nothing that fully adapts to changes in the incoming audio. It's been so easy to use ANR-B and all the operators really like the unit."
