Comments High-quality audio not only delivers a higher bit rate but can adapt to the speed of your internet connection by increasing or decreasing that bit rate. Netflix video already does something similar. If you’ve ever been on a slower connection, you have probably seen video playback at a lower quality until there’s enough of a buffer for it to switch to a higher quality version. High-quality audio will do the same and move up and down in quality seamlessly as you watch a show.Currently high-quality audio is rolling out to TVs and connected boxes with support for 5.1 or Dolby Atmos. Devices with 5.1 will receive a bit rate of 192 to 640 kilobits per second. If you’re a Premium Netflix subscriber and have an Atmos device, playback will be between 448 and 768 kbps. Tags Netflix teases Stranger Things season 3 in new trailer Netflix I had a chance to experience the new high-quality audio listening to a sequence from Stranger Things. There were three versions: the original master, a low bit rate one (192 kbps) and a higher bit rate one (640 kbps). The low bit rate version sounded fine, but when compared to the original master it lacked subtle audio details and clarity. The high bit rate version, to my ears, was identical to the original master achieving a phenomena called “perceptually transparent” — don’t worry, I didn’t know what that meant at first either.Perceptually transparent — which, by the way, would be a great name for an improv group — means there are no perceived differences between a studio master and audio that has been compressed. For Netflix streaming that perceptually transparent sweet spot was 640 kbps.Netflix said that these bit rates might “evolve” over time as the company gets more efficient with its encoding.

The streaming company has released a new feature called high-quality audio that makes sure what you hear is closer to what the artists behind your favorite show intended. Netflix’s improved audio came about because of the show Stranger Things’ second season.The first episode of Stranger Things season 2 starts off with a car chase. But when the Duffer brothers, the show’s creators, first heard it played back in a living room, they noticed that the sound wasn’t as crisp as the original master from the studio.”It didn’t sound quite as defined. A little bit mushy, you might say. Or like maybe there’s a napkin over it,” said Scott Kramer, manager of sound technology for Netflix. “Very subtle, but noticeable.”To address the issue, the show was streamed at a higher bit rate that sounded closer to the original studio master. This laid the groundwork for Netflix to create its new high-quality audio feature. TV and Movies Audio Now playing: Watch this: 2:50 Share your voice 24
Rohit Sharma became a father to Samaira last yearRohit Sharma TwitterRohit Sharma is one of the best batsmen in limited-overs cricket and the captain of Mumbai Indians. But apart from this, the Mumbai cricketer also happens to be a doting father who is not hesitant to show his love for his newly-born daughter Samaira.With a day to go for the IPL Final, Rohit Sharma again took time off to play with his daughter. The official Twitter handle of his team Mumbai Indians, put out a video where the young father is showering his affection on Samaira. Daddy Ro reporting on duty ✅?#OneFamily #CricketMeriJaan #MumbaiIndians #MIvCSK @ImRo45 @ritssajdeh pic.twitter.com/0NWvqLtAha— Mumbai Indians (@mipaltan) May 11, 2019Rohit Sharma playing with his daughterTwitter/Mumbai IndiansThis is not the first time that the India opener has been seen on Twitter in this role. Earlier in the season also, he posted a video of himself giving Spanish lessons to his daughter. After his team had won the first qualifier of the ongoing season of IPL, he had posted a picture of himself and his wife sitting on the Wankhede outfield with their daughter. The text accompanying the photograph said: “At the end, this is what matters the most.”Rohit, who is 32 years old, got married in December 2015 to Ritika Sajdeh and the couple became parents in December last year. His wife has been seen often at stadiums supporting her husband while the whole family has been together during most of the season.It has become common among Indian cricketers of current generation to have their families with them and their spouses and partners present at the stadium. It is a sea change from earlier generations of cricketers who were rather discreet about showing their emotions in public.Both Sharma and India captain Virat Kohli have acknowledged their wives on field as well after getting to landmarks. While that may draw a mixed response from people used to watching the likes of Sachin Tendulkar and Rahul Dravid maintain stoicism about their personal feelings, the pictures and videos of Rohit Sharma with his cute daughter are bound to melt the heart of most sensitive people.
As archaeologists continue to piece together human history, they look for new ways to interpret evidence that may already be in hand—such as ancient human bones or fossils. By studying the way the skeleton has changed from the time when our ancestors were in Africa until today, researchers have created a kind of map of the migration of humans around the world. In this new effort, the researchers focused on the bony labyrinth, the three bones of the inner ear—the cochlea, vestibule and semicircular canals. Together, they appear as a sort of labyrinth for which they were named. The researchers started with the knowledge that as time passes, bone structure tends to change—and the bony labyrinth has proven to be particularly hardy, remaining mostly intact in skeletons when arms, legs and other bones have been broken, crushed or lost completely. They further noted that earliest humans that migrated from Africa would have had the longest amount of time to evolve as they moved to other places. And those that migrated the farthest would likely be among those who migrated the earliest. This, they believed, suggests it should be possible to use evolutionary changes in the bony labyrinth as a means for charting human migration.To test their theory, the researchers collected and analyzed 221 skulls, which included 22 unique populations from various time periods. They looked at the differences in the bony labyrinths, and once they had been identified, the researchers compared the differences they found with data from other studies attempting to create migration maps.The team reports that their original idea aligned with their research data—those humans with the greatest amount of change in their inner ear bones were among the group that left Africa the earliest and traveled the farthest, demonstrating that the bony labyrinth could, indeed, be used as a new tool to help in adding pieces to the puzzle of human history. An international team of researchers has found that it is possible to use the human bony labyrinth of the ear as an indicator of dispersal from Africa. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of hundreds of ancient ear bones from around the world and the differences they found among them.

DOI: 10.1073/pnas.1717873115AbstractThe dispersal of modern humans from Africa is now well documented with genetic data that track population history, as well as gene flow between populations. Phenetic skeletal data, such as cranial and pelvic morphologies, also exhibit a dispersal-from-Africa signal, which, however, tends to be blurred by the effects of local adaptation and in vivo phenotypic plasticity, and that is often deteriorated by postmortem damage to skeletal remains. These complexities raise the question of which skeletal structures most effectively track neutral population history. The cavity system of the inner ear (the so-called bony labyrinth) is a good candidate structure for such analyses. It is already fully formed by birth, which minimizes postnatal phenotypic plasticity, and it is generally well preserved in archaeological samples. Here we use morphometric data of the bony labyrinth to show that it is a surprisingly good marker of the global dispersal of modern humans from Africa. Labyrinthine morphology tracks genetic distances and geography in accordance with an isolation-by-distance model with dispersal from Africa. Our data further indicate that the neutral-like pattern of variation is compatible with stabilizing selection on labyrinth morphology. Given the increasingly important role of the petrous bone for ancient DNA recovery from archaeological specimens, we encourage researchers to acquire 3D morphological data of the inner ear structures before any invasive sampling. Such data will constitute an important archive of phenotypic variation in present and past populations, and will permit individual-based genotype–phenotype comparisons. © 2018 Phys.org Explore further The inner ear of modern humans shows subtle shape differences between populations, tracking human dispersal from Africa (colors symbolize dispersal distance from sub-Saharan Africa).
