Dolby Surround

David has a home theater system and the speakers are already built into the house, but he needs surround speakers. Leo says he can do that and then just wire them into his home theater system. It'll be the rear surround in a 7.1 Dolby system. Or, if he doesn't want to do that, he should just go with Dolby 5.1. He'll be just fine with that. He'll need to re calibrate, too. Of course, he could go all in and do Dolby Atmos at home, too.

Scott is going to the Grammys this weekend and he says the best part of the awards show is all the live performances. He also says that it's the Super Bowl of music and it's a great time to think about upgrading your home theater system. Leo has an AV receiver with Dolby 5.1. He's perfectly happy with the surround, center channel, two channel speakers, and a subwoofer.

The question of the day is: what's more important, video or audio? Scott says that a movie without sound is called a silent movie. But on the other hand, a movie without an image is called radio. So Scott believes they are equally important, like the Yin and Yang of home theater. However, the bad audio can really make the home theater experience terrible, which is why surround sound and home theater really exists.

How can old movies be in surround sound?

Charles from New York, NY

Episode 1098

Charles is annoyed with Netflix' attempts to encode movies in mono that are being decoded into stereo. He's also noticing that old movies on Blu-ray are doing the same thing. Is there a new 2 channel stereo to 5.1 surround conversion technology going on? David says that there are certain older movies that have remixed in Blu-ray and it's likely those are the movies that have been used, and Netflix is likely using that remixed master. Scott says that Dolby Pro-Logic can also take a standard stereo signal and spread it out over Dolby 5.1 surround.
