Dolby Headphone is a unique signal processing system that enables your stereo
headphones to realistically portray the sound of a five-speaker playback system.
It can be incorporated into virtually any type of audio or video product
normally featuring a headphone output, and is identified by the Dolby
Headphone (left) and Dolby Headphone Stereo (right) symbols on the unit or
one of its controls.

So, what do you get for your seventeen-quid-and-a-bit? Quite a lot that's going to deafen your neighbours if played at the right volume.
First off are a couple of six-minute pieces, an Introduction to Dolby Labs and The Dolby Digital Story, which tell the tale of what Ray Dolby (above) achieved and include examples of Dolby Digital 5.1 sound. However, they don't touch upon either Dolby Digital Surround EX 6.1 or the invention of Dolby Headphone.
If you wanted a collection of top-notch Dolby Digital trailers that you may have seen in the cinema then look no further. The first four I've seen before and there are three that are new to me.
Train : Starting with a misty, grey haze and extreme surround effects from separate speakers, a train eventually emerges and thunders off into the distance.
Canyon : More subtlety as what starts off seemingly as a jungle scene ends in the Grand Canyon.
Egypt : Another clever use of DD5.1 that quietly begins but closes in a crescendo of sound as an Egyptian temple is revealed.
Aurora : A space-based demo with the Dolby Digital logo appearing after what looks like a rip in the space-time continuum.
Rain : The Dolby Digital logo appears amongst a brilliant CGI effect of raindrops falling on water.
Game : My favourite of the trailers I hadn't seen before. One to test the speakers to the limit, this combines the feel of Battlezone, Carmageddon and Half Life into a few seconds of Dolby Digital joy.
Finally comes some short musical pieces to try out on your system.
Allegro in D Major : Performed by Pacific Guitars, this is a piece of classical music lasting 140 seconds and available in the same sound formats.
San Fernando Valley : Performed by Flying Without Instruments, this is a near-3-minute encapsulating acapella number performed in Dolby Digital 5.1 only.
The picture is faultless, the Dolby Digital trailers having an average bitrate of 8Mb/s, while the rest is mostly a collection of static images. Most of the content is in a fullscreen 4:3 ratios, although some of the trailers are in a 16:9 ratio.
Note that the disc has been mastered in NTSC so ensure you connect your DVD player to the TV with the SCART or S-video socket.
If I was to say anything bad about the sound, I'd expect Mr. Dolby to come round and break my legs, but you can rest assured that the sound from this Dolby Digital Demo is spot-on. However, while I only have a surround sound setup so was not able to check out the DD5.1 samples on this disc in all their glory, I have seen some of them in the cinema and both those and good uses of DD5.1 sound in films are enough to make you stand up and applaud.
There is also a "Loop" option which plays everything in menu order. I guess this is how the website got a total running time of just over 60 minutes as the whole content is included twice: once individually and once in a loop.
The sound accompanying the menus is a medieval affair of soft guitar music.
Overall, if I could want something more from this disc it would be a set of test signals outside of the "Dolby Digital Story" - and a nice bonus might have been to include something along the lines of "Video Essentials" to help set up the geometry of my TV, if this had been possible.
Other than that though, it's a first rate demo collection and one to dig out when your friends pop round and you want to impress them.
Dolby are right when they say "We've got the whole world listening". When I'm watching a film, I let *ALL* my neighbours know by turning the volume up to eleven.
N.B.: The website states a price in US$ but a copy of this disc can be ordered
