  • An Innovative Solution to Inconsistent Volume Issues
    Technical Paper Dolby® Volume: An Innovative Solution to Inconsistent Volume Issues As home entertainment options have increased—more channels, more media, more content—so have inconsistencies in perceived volume levels. Listeners must constantly readjust their volume controls to maintain consistent playback levels as they choose from among their many program options. Even content within the same program can vary in level, often dramatically, requiring even more volume control adjustments. And with content from the Internet and social media becoming part of the traditional home entertainment experience, volume inconsistencies are likely to increase further. Dolby® Volume technology is a groundbreaking solution to this problem. More than 40 years of engineering experience in noise reduction, perceptual audio coding, and related psychoacoustic technologies have gone into its development. Incorporated into products such as A/V receivers, set-top boxes, and TV sets, Dolby Volume continuously monitors and adjusts the audio to maintain the listener’s preferred perceived playback level—across all channels, all program sources, and all content. With Dolby Volume, the listener can select a preferred volume level for a more consistent and enjoyable listening experience—and never have to reach for the remote control again. Dolby Volume also addresses the ear’s changing sensitivity to different frequencies at different playback levels. At normal home listening levels—usually significantly lower than the reference levels used in the mixing studio—the listener does not hear the original tonal balance, or timbre, of the mix, and subtle surround effects intended to set the mood can actually disappear. Employing loudness domain signal processing and a highly sophisticated psychoacoustic model of human hearing, Dolby Volume monitors the difference between reference level and the listener’s actual listening level, and dynamically fine-tunes the level in each channel to maintain all the characteristics originally intended by the content producers and mixers.

The radio, then black-and-white TV, then color TV, and then all the various adjuncts to the TV and radio — VCRs, gaming consoles, tape decks, and so on — have all helped define who we are and how we inter- act with each other. The home has grown around these devices, so when it comes time to put these together on a pedestal and proclaim them a home theater, this act seems to acknowledge the role that home electronics have grown to play in our lifestyles.

Well, a home theater is largely what you make of it, but we think that at least three major things constitute the core of a home theater: ߜ A large screen display: Note that we do not say television, because more and more, the receiver aspect of a television is being divorced from the display aspect, in the form of set-top boxes, external TV tuners, computers, and other source devices. Appropriately, the display is being opti- mized for what its main purpose is — displaying the wide range of video output from a home the- ater system.

  • Dolby Atmos for Sound Bar Applications
    Dolby Atmos for sound bar applications June 2018 1 Since its introduction in the movie theatre in 2012, Dolby Atmos® has revolutionized cinema sound and reinvigorated home entertainment. Dolby Atmos introduces the concept of object-based audio, in which sounds are represented as individual objects that can be located anywhere within the space above and around the listener. With Dolby Atmos tools, content creators can precisely place and move sounds anywhere in your living room, including overhead, to make entertainment incredibly immersive and lifelike. Dolby Atmos and audio objects Dolby Atmos in the home is an object-based audio format with the capability to reproduce up to 128 simultaneous objects that may be present in the original cinematic mix. Every sound in a scene — a mosquito buzzing, a helicopter taking off, a car horn blaring — can be represented as a separate audio object that can be positioned and moved throughout the three-dimensional space. The car speeds from left to right; police officers search the upstairs floor, walking back and forth; the hawk swoops through the woods, clipping tree limbs as it flaps its wings to gain altitude. Using sophisticated content creation tools that represent the audio objects in a three-dimensional space, filmmakers can isolate each audio object in a scene and decide exactly where they want it to be and how they want it to move. In the final sound mix, the audio objects are combined with positional metadata — data that describes each audio object, including its location, its size or intensity, and its movement. Figure 1. Filmmakers can use this Dolby Atmos tool to position and direct audio objects throughout the three-dimensional space.

    Home Theater: What You Need To Know PRESENTED BY: 777 St. Clair St | Chatam, ON | 1-800-SHOP-APW | www.apwelectronics.com Introduction Welcome to the Movies . Home Theater isn’t new. It began back in the 1920s and 1930s when Hollywood’s elite built screening rooms in their homes so they could view the films they had just produced, directed, or starred in. Even though they were luxurious, early “home theaters” were complex and intimidating. The moguls who enjoyed them kept technicians on staff to run the noisy and cantankerous projectors of the day. Technology has come a long way. Today, home theater systems are far more convenient, far more accessible, and far more reliable. And, thanks to the efforts of literally thousands of engineers, designers, and installers, they’re far more capable, too. A good home theater system will provide hours of enjoyment for you and your family as it literally immerses you in sights and sounds once available only at the very finest first-run movie houses.

  • Efficiency Assessment of Modern Home Audio Equipment
    Efficiency Assessment of Modern Home Audio Equipment Benjamin Ealey, Jeff Dols, Brian Fortenbery, Frank Sharp, Micah Sweeney Electric Power Research Institute ABSTRACT The emergence of efficient switch-mode power supplies and efficient Class-D amplifiers has provided a means for additional energy savings in home audio devices. The sale of home audio devices continues to grow. There are more categories of home audio products in today’s market than ever before. The variety in home audio products has not taken away from the sale of traditional home-theater-in-a-box systems and audio separate systems, which have remained steady in sales. Adding to this, the cost of home audio devices has decreased over the years because of reductions in the cost of electronics. This has increased sales because home audio devices are now more affordable than ever. The increased sale of portable media devices (smart phones, tables, media players) has led to an increase in home audio devices because of the volume limitations of portable media. This has especially had an impact on the sale of portable speakers and bookshelf speakers. These factors are increasing the number of home audio devices a typical consumer owns. It is important that energy efficiency is assessed because with more sales, the total energy consumed by home audio devices increases. However, there are efficiency improvements that can be included in the design of home audio devices to reduce this impact. Before action is taken, the current state of efficiencies must to be examined to help direct where efforts will be best spent. This project utilizes a newly developed test procedure to provide clarity on the performance of existing products by testing device energy consumption at different sound pressure levels in a controlled environment.
