I think that EX or ES is noticeable in a theater. Smart has a line of decoders that for the extra channels that seem to work well on the rear channel and even where it was set up in the sound tracks to imitate a rear channel or simulate it. I have been in several theaters that were equipped with those Smart units and the rear channel coming from behind you was very evident! I haven't been any that uses the over head yet!

We just got the Smart Circle Surround unit and I must say, this unit extracts out-of-phase information even tho it's the tracks are not specifically encoded as EX, much like playing two channel sources thru those old quadraphonic decoders would extract ambience audio. The Smart unit allows you to engage the decoding or not. It's not automatic, so you can choose to use it or not. Our experience is that it enhances the surround experience even on nonEX encoded prints.

I suppose it is possible to encounter surround tracks were using the decoder will cause weird anomolies, but for those, when they do occur, the decoder can simply be switched off, but other than that eventuality, just leaving it on all the time seems to be an enhancement that works well. It makes you feel that you are immersed in the surround audio -- it REALLY surrounds you.

EX works with in-phase audio material, not out-of-phase (there were rumors I heard long ago of an EX expansion which would place the out-of-phase surround information in an overhead channel). It simply Pro-Logic's the surrounds. Super-simple technology that should cost no more than $100 max for that function. Material does not need to be specifically encoded. There is nothing magical about the encoding. It's all in the mixing which is super easy to do. Many of my home movies are in surround EX. If it is in-phase, it goes to the back surround. You will get no more anomalies than you do watching stereo material on a Pro-Logic system.

'Soldiers' returns with state-of-art sound system

By Bill Muller
The Arizona Republic
Sept. 17, 2002

A state-of-the-art theatrical sound system makes its national debut in Tempe this week, with the re-release of the Mel Gibson Vietnam war saga We Were Soldiers.

Sonic Whole Overhead Sound was designed at the urging of We Were Soldiers director Randall Wallace, who wanted audiences to experience the full impact of his film's sweeping battle scenes.

"When the jets scream over . . . audibly it's exactly what happened," says Wallace, who worked with Paramount Pictures, sound designer Lon Bender and Dolby Laboratories to create the effect.

"The sound in this story surrounded these soldiers, and I wanted the experience of the film to be subjective," he says.

For the special engagement, which begins Friday at the Harkins Centerpoint 11, a theater will be outfitted with four speakers on the ceiling, integrated into the existing Dolby EX surround-sound system.

Wallace predicts that in 10 years, "every significant theater in the country will have this kind of presentation."

The film offered a great opportunity to showcase overhead sound, says David Gray, vice president of Hollywood film production for Dolby, which won't hesitate to look for future applications.

"We Were Soldiers was fabulous," Gray says, "because of all the helicopters and the mortar shells and the sort of huge battle landscapes where you have lots of sounds and lots of depth and lots of dimension."

The movie initially opened in March. The reviews were so good and the audience reaction so strong, that Paramount decided to re-release the film closer to Oscar time. That gave Wallace the opportunity to push for the new sound system.

Gray says the technique allows the sound mixers to reproduce effects that were never possible before, such as the whirling rotor blades of a helicopter directly overhead.

"The whole thing of feeling engulfed improves," he says. "Because now you have the third plane."

The one thing you have to look out for with leaving "EX" in all the time is a surround track that was mixed mono, more or less. In an EX system...that will play from the rear only. In a 5.1 system, it will play out of all surrounds. But that seems to be the only case where EX all the time really changes the feel of the mix. Otherwise, EX all the time can help with steering.
