Dolby Laboratories, Inc. today announced the ability for studios, authoring houses, and mastering facilities to unlock the full sonic potential of television, movie, and music content, further elevating playback performance of lossless audio on Blu-ray Disc.
Blu-ray Discs premastered using Dolby® TrueHD with advanced 96k upsampling can now deliver to consumers a full-range high-definition surround sound experience ensuring optimum performance from today’s advanced A/V receivers and Blu-ray Disc players. The new Dolby TrueHD coding solution enables facilities to integrate the benefits of 96 kHz playback quality audio into the final master while simultaneously reducing the incidence of digital artifacts introduced during the content-creation process.
“Lossless audio is a key distinguishing feature of Blu-ray content. All things being equal, you cannot improve on the quality of lossless audio coding; however, you can improve on the quality of the source PCM content prior to lossless encoding, and this is precisely what we have achieved with our advanced 96k upsampling technology,” said Craig Eggers, Director, Content Creation and Playback, Home Theater Ecosystem, Dolby Laboratories. “A significant amount of Hollywood content has been captured in native 48 kHz. Studios and authoring facilities that implement Dolby TrueHD with advanced 96k upsampling can elevate the quality of PCM audio prior to lossless Dolby TrueHD encoding, ensuring that consumers get the very best audio performance possible from their Blu-ray playback systems.”
Besides enabling optimum 96k upsampling, this technology features a unique apodizing filter that “masks” the unwanted digital artifacts known as “preringing,” which is introduced during the content-capture and content-creation process. These digital artifacts can introduce an unnatural edginess or harshness to the audio. Dolby TrueHD with advanced 96k upsampling restores the natural tonality of the soundtrack. The effect can be subtle or dramatic, depending on the quality of the source material. Content mastered with Dolby TrueHD with advanced upsampling is fully playback compatible with all Dolby TrueHD enabled Blu-ray™ players and A/V receivers. Listeners are assured the highest-quality playback experiences possible through their systems.
Respected authoring houses and mixing facilities worldwide have recently upgraded to Dolby TrueHD with advanced 96k upsampling within the Dolby Media Producer Encoder v2 to provide customers with the highest-quality audio experience available on Blu-ray. These facilities include United States-based Deluxe Digital Studios, Giant Interactive, Mi Casa Multimedia, POP Sound, and Technicolor®; and leading Greater China-based companies Best & Original Production Limited, Hualu Publishing & Media Co., Ltd., and Media Asia Films.
Dolby plays a critical role in ensuring that the artistic intent of the audio mix is maintained through the entertainment ecosystem, from the soundstage into the home theater. Dolby TrueHD delivers powerful sound that is bit-for-bit identical to the original studio master, unlocking the full entertainment value of Blu-ray Disc and other HD media. The advanced 96k upsampling raises the bar for playback of movies, television, and concert films mastered for Blu-ray Disc. Beyond the Greater China release of The Flowers of War, Blu-ray Disc titles including the Joe Satriani concert film, Satchurated: Live in Montreal, and San Francisco Symphony at 100 have been premastered using Dolby TrueHD with advanced 96k upsampling.
