Qualcomm Unveils aptX Adaptive Codec to Deliver High Quality, Low Latency Audio

When it comes to streaming music on a Bluetooth device, uneven latency and quality drops are among the major issues, which is why audiophiles still prefer wired music devices for a better listening experience. To address the issue, Qualcomm has today announced aptX Adaptive, the next generation of aptX audio codec which claims to deliver higher quality audio with minimal latency issues by employing a dynamically adjustable audio compression technology.

As per Qualcomm, aptX Adaptive combines parameters such as audio quality, scalability, low latency and low bitrate audio transmission to provide an unmatched wireless music listening experience. The company claims that the new audio codec detects the audio waves in the surroundings and automatically adjusts the aforesaid parameters to deliver a superior audio experience, be it gaming, watching movies or listening to music.

“Adaptive technology is uniquely engineered to automatically adjust to provide optimum audio quality or latency depending on the type of content being played on the device while also taking into account the external RF environment to support a robust connection”, Qualcomm said in an official blog post. So, how does the Qualcomm aptX Adaptive codec prove to be useful? Well, the new audio codec can compress audio at variable bit rate by identifying the surroundings and the particular need of users, such as attending calls, listening to music or gaming.

So, if you are in a noisy surrounding, the audio will be compressed in a smaller size to make it easier to stream the music file to the connected Bluetooth device, reducing latency issues in the process. In case users are in surroundings with minimal disturbance, aptX Adaptive will compress the audio into a higher bit rate file to deliver a superior quality listening experience.

As far as availability is concerned, the aptX Adaptive decoder will come bundled with the Qualcomm CSRA68100 and the Qualcomm QCC5100 series of Bluetooth audio chips for headphones, headsets and speakers starting September 2018. Qualcomm will also release a version of the aptX Adaptive encoder for tablets and smartphones running Android 9 Pie in December this year.

Lenovo IdeaPad Slim 5i Review: A Powerful Workhorse

It’s been quite some time since Intel announced its 11th-gen laptop processors, complete with the new logo design and Intel Iris Xe graphics. And yet, so far I’ve not gotten my hands on a laptop packing the new processor and iGPU. That all changed when Lenovo sent over the IdeaPad Slim 5i (Rs. 61,990) with […] The article Lenovo IdeaPad Slim 5i Review: A Powerful Workhorse was first published on Beebom

Twitter Wants to Build an ‘Open and Decentralized’ Social Media Platform

In an attempt to create a Facebook competitor, which everyone flocks to, Twitter became increasingly centralized over the years. Twitter CEO Jack Dorsey believes that’s the case and has now tweeted a lengthy plan to fund research to build an open and decentralized standard for social media platforms. It will “ultimately become a standard” that Twitter’s client will be based upon. Dubbed Bluesky, this project will see a team of up to five researchers , which could include open-source architects, engineers, and designers, being on-boarded in the near future. Currently, Bluesky has no team members but Dorsey tweeted that Twitter’s CTO Parag Agrawal has been tasked with finding a lead. The folks over at Firefox have already extended a helping hand, saying how the non-profit has contributed to decentralization. Enough jibber-jabber, but what exactly is Bluesky? And what does it intend to achieve? Dorsey, in his tweetstorm , states that the challenges being faced by centralized social...

Mysterious Drones Spotted in Colorado and Nebraska; Sources Unknown

A group of drones was reportedly been spotted in the sky at night last week in Colorado and Nebraska that made the residents anxious and worried. The police officials in charge have no idea regarding where these drones are from. “They’ve been doing a grid search, a grid pattern. They fly one square and then they fly another square,” Colorado’s Phillips County Sheriff Thomas Elliot told the Denver Post. The drones have an approximate six-foot wingspan and stay 200 to 300 feet away from buildings. At least 17 drones have been spotted till now. They appear at around 7 PM at night and disappear at around 10 PM . Until now, the drones have not been caught doing any illegal or unofficial activities. “They do not seem to be malicious. They don’t seem to be doing anything that would indicate criminal activity,” Sheriff Elliott added. The Federal Aviation Agency, the Air Force, Drug Enforcement Administration, and US Army Forces Command confirmed that the drones did not belong t...
