Hi, this is Wayne again with a topic “Dolby As Fast As Possible”.
Part of the reason why we’re willing to pay out the freaking nose for movie tickets is that primo, sound you get at the theater and indeed a huge part of marketing these days for cinema chains is pushing their audio technology. That promises some sort of transcendental experience for your ears, but years ago, Dolby Laboratories, you may recognize a little indication on games movies or even someone’s receiver under their TV started, trying to bring a theater like experience to the home. They, like other competing companies such as DTS, provide compression technologies for audio streams, so that they’ll fit onto a disc, much like how one might compress a video file to make it suitable for the net. I’M looking at you, h.264 Dolby’s technology was born many years back with Dolby stereo.
If you are budding audio enthusiasts in 1975, you might remember seeing Dolby stereo being tossed around what was special about. It was that it took your conventional stereo sound and created a four channel surround experience in the theater through some mathematical trickery, with the sound encoding, but it wasn’t until 1982 that the home was first introduced to Dolby technology with Dolby Surround another analog technology. That added a mono surround channel to the usual front, left and right.
This was improved with Dolby Pro Logic, which added a center channel and used in more advanced algorithms, who not only extract the extra channels but to also improve the movement and discreteness between them. Pro Logic still exists today in a new and improved form, with the ability to mix stereo or surround 29.1 channels. As technology progressed, it became easier to record multi-channel, sound natively and so Dolby Digital debuted in 1992, featuring six discrete channels of audio in the ubiquitous 5.1 setup.
Five speakers, one subwoofer since then, we’ve seen incremental updates to the technologies with improvements to the number of channels. As well as maximum bitrate and sample rate in the case of Dolby, true HD, a lossless audio codec. So what does the future look like? Well, in order to blow your mind, the new dolby atmos now supports up to 128 audio objects that are independent of a channel assignment.
Why is this better? Well, imagine a helicopter flying over you. Instead of a conventional system vaguely telling your ears where the chopper is flying with Dolby Atmos sounds, can be created independently and maps to a specific location, so you’ll be able to pick out exactly where it is at most also scales. The specific speaker structure of the theater and does this in real-time, so in theory, you should hear a spatially, accurate effect, no matter where you sit put this all together and voila, you can almost feel like you’re there and if you don’t want to pay 9 freaking Dollars for a bucket of popcorn dolby has now expanded this technology into the home.
It does require a compatible AV receiver, which supports the extra channels needed to make this possible. The more speakers you have by the way, the better but at most will work with at least 6, so you won’t necessarily need to sell an entire kidney to make it happen.
