In the end, the city chose a more immediate solution. The renovations followed years of discussion about building a new arena, including a 2007 report commissioned by the Maryland Stadium Authority that found the structure had “served its useful life” and should be replaced by a new 16,000-seat facility. “But when you see what’s happening with our partners at Oak View Group, when you see that the tickets are selling out, you know that we now have a world-class venue right in downtown Baltimore that the taxpayers didn’t have to pay for, that will drive people into the core.” “Some folks told me that I was crazy that we were putting lipstick on a pig,” recalled Mayor Brandon Scott. ![]() Supporters of the latest renovation say the updates to the interior of the arena will do the trick and hopefully jump start a downtown area that is reeling from a population drop, the pandemic and concerns about crime. It was part of an urban renewal effort in downtown Baltimore in the late 1950s and 1960s that also included the construction of Charles Center. in the futuristic Googie style with a roofline that evokes pyramidal shapes, opened in 1962 as the Baltimore Civic Center. The arena, designed by architect Arthur Gould Odell Jr. The California-based venue development and management company will draw upon the vast cadre of arenas and venues it has built or operates across the country, including the new UBS Arena, which is home to the NHL’s New York Islanders Seattle’s 61-year-old Climate Pledge Arena, where the WNBA’s Seattle Storm play and XL Center in downtown Hartford, Connecticut, where the University of Connecticut men’s and women’s basketball teams play.Īfter a private concert by Earth, Wind and Fire on Thursday and Friday’s Springsteen show, which comes nearly 50 years after he first played the Baltimore Arena on June 2, 1973, it will be full steam ahead with superstar acts such as the Eagles, Janet Jackson, New Edition, Anita Baker and Lizzo.ĭevelopers and city officials alike are quick to acknowledge that the old arena was in need of work - going as far to say that major acts would skip over Baltimore and go to nearby cities with better venues such as Washington, D.C., and Philadelphia. The Baltimore Banner thanks its sponsors. He also remembers when Barack Obama, then a candidate for president, came to the arena for a rally in 2008.īut he also recalls the complaints that artists and guests had about the acoustics of the aging building as well as the logistical problems of setting up a concert there, and the lack of amenities compared to those in other top-market cities. He was there for the slew of professional wrestling events throughout the 1990s and 2000s. He remembers in 1995 - the last time the venue hosted an early round of the NCAA men’s tournament - when he warned Bryant “Big Country” Reeves, Oklahoma State’s 7-foot center, that if he broke another backboard, the games in Baltimore would have to cease because the arena had run out of replacements. Remesch, the general manager for the arena, has worked there for 35 of its 61 years. “This is something I never thought I would see to fruition.” “You’re in for a treat,” he said as a barrage of horns blared, hydraulics hissed, and workers chattered throughout and around the arena. Work crews and large hulking equipment feverishly completed various tasks ahead of the venue’s first big tests - a private Thursday night concert by Earth, Wind and Fire and the public debut featuring Bruce Springsteen and The E Street Band on Friday night. Frank Remesch stood amid a sea of reporters in “The Bowl,” the massive rectangular open space at the heart of the newly reimagined CFG Bank Arena. ![]() We can add rows to Treeview only after getting confirmation of adding record to MySQL database.

![]() “We’ve put a bunch of neat features in there and places for them to chat and hang out and they’re going to be able to learn from the code that we wrote for that community space… So a few weeks later or a month later they can put that into their experiences and turn it on,” Bronstein said.īronstein emphasizes that Roblox will take this process slowly, building new moderation and safety tools in parallel as it goes. The company is inviting an initial group of 5,000 developers, all 13 and older, to try out the new spatial voice chat capabilities in a custom-built Roblox community space. ![]() Voice chat is very much on the way to Roblox, but that doesn’t mean it will appear overnight - and that’s by design. “And part of bringing voice to the platform is to ensure that our older audiences have a natural way to communicate.” “If you think about the metaverse as the next incarnation of where you know I could go shopping or I could go to a concert, I could go to school, I think that you need to be relevant to everybody in society and you need to both build the content, the rules, the features that support all of those behaviors,” Bronstein said. Prior to hopping over to Roblox, Bronstein worked on product teams at Zynga, Xbox and YouTube - three very different companies that are probably equal parts relevant to his current work. “But it also can transcend, some of the limitations that physics and space create in the real world.”īronstein joined the company in March, leaving Google to help realize Roblox’s particular vision for the metaverse. “As we think about the future of communication in the metaverse, we think that it needs to be very natural and feel very similar to the way we communicate in the real world,” Roblox Chief Product Officer Manuel Bronstein told TechCrunch in an interview. To have a private conversation with a nearby friend, you might peel off and walk toward a store down the block. But you wouldn’t be able to hear someone walking around on the sidewalk across the street, since they’re too far away. Say you’re hanging out in a virtual skatepark in Roblox with spatial audio enabled: skaters in the halfpipe with you would sound loud and clear, just like they would in real life. Roblox sees its new voice product as a natural extension of the way that text chat works now, but instead of text bubbles that pop up over an avatar’s head, visible to anybody around them, players will be able to talk naturally to the other people they bump into. With spatial voice, users will be able to speak with other people nearby through live voice chat. ![]() The first move: inviting a group of trusted developers to explore how they can integrate proximity-based audio into the wildly popular experiences that beat at the heart of the platform - from chill, vaporwavey vibe games to pulling off kickflips in a Vans-sponsored skate park. To that end, Roblox is taking careful but decisive steps toward weaving voice chat into the platform’s core experience. And while the platform has had no shortage of growth on its current path - as of July, it boasted 47 million daily active users - it’s looking to chart a course toward deeper, richer virtual experiences that will keep people coming back for years to come. As one of the frontrunners in the race to build the metaverse, Roblox is thinking ahead to what virtual worlds really need. ![]() ![]() Migrate SQL Server workloads to the cloud at lower total cost of ownership (TCO) Manage and scale up to thousands of Linux and Windows VMsīuild and deploy Spring Boot applications with a fully managed service from Microsoft and VMwareĪ dedicated physical server to host your Azure VMs for Windows and LinuxĬloud-scale job scheduling and compute management Protect at the speed and scale of AI with a generative AI-powered assistantĪccess cloud compute capacity and scale on demand – and only pay for the resources you use.

And note that if you don't have an internet connection, or if for some reason the voice audio download isn't working for you, you can also use a recording app that records your devices "internal" or "system" sound. Note: If you have offline-compatible voices installed on your device (check your system Text-To-Speech settings), then this web app works offline! Find the "add to homescreen" or "install" button in your browser to add a shortcut to this app in your home screen. You can also adjust the pitch of the voice to make it sound younger/older, and you can even adjust the rate/speed of the generated speech, so you can create a fast-talking high-pitched chipmunk voice if you want to. You could use this website as a free voice over generator for narrating your videos in cases where don't want to use your real voice. You're free to use the generated voices for any purpose - no attribution needed. As mentioned above, the downloaded audio uses external voices which may be different to your device's local ones. If you don't know how to install more voices, and you can't find a tutorial online, you can try downloading the audio with the download button instead. Many operating systems (including some versions of Android, for example) only come with one voice by default, and the others need to be downloaded in your device's settings. Note: If the list of available text-to-speech voices is small, or all the voices sound the same, then you may need to install text-to-speech voices on your device. You can even use it to reverse the generated audio, randomly distort the speed of the voice throughout the audio, add a scary ghost effect, or add an "anonymous hacker" effect to it. For example, you can make the voice sound more robotic, or like a giant ogre, or an evil demon. Want more voices? You can download the generated audio and then use voicechanger.io to add effects to the voice. If you don't like the externally-downloaded voice, you can use a recording app on your device to record the "system" or "internal" sound while you're playing the generated voice audio. You can download the audio as a file, but note that the downloaded voices may be different to your browser's voices because they are downloaded from an external text-to-speech server. This web app allows you to generate voice audio from text - no login needed, and it's completely free! It uses your browser's built-in voice synthesis technology, and so the voices will differ depending on the browser that you're using. The order of the points does not matter for the formula as long as the points chosen are consistent. Where (x 1, y 1) and (x 2, y 2) are the coordinates of the two points involved. Precision, accuracy, and a respect for the environment are what make a true outdoorsman – and a rangefinder scope is a tool that helps you achieve that.The distance between two points on a 2D coordinate plane can be found using the following distance formula Technology such as the laser rangefinder is not just a gadget it's a tool that, when used correctly, can be a game-changer in how you engage with outdoor pursuits. Whether you are a seasoned hunter or a novice in the field, understanding your environment and accurately measuring your range can make a world of difference. Incorporating a rangefinder scope into your hunting gear can significantly enhance your precision and success. ![]() With an ATN rangefinder, hunters can effortlessly measure distances to their targets, ensuring an accurate shot without having to rely on guesswork. This intricate process takes place in a fraction of a second, providing hunters with quick, reliable distance readings. The beam then bounces back to the rangefinder, and the time it takes for the beam to return is calculated to measure the distance. These rangefinders use a sophisticated laser beam that is fired at the target. How do ATN Rangefinders Measure Distance?ĪTN rangefinders, specifically designed for hunting, have emerged as a game-changer in the field. In areas where the use of rangefinders is legal, they can significantly enhance a hunter's ability to estimate distances accurately, leading to more successful and ethical hunting experiences. As a responsible hunter, it is vital to be familiar with local hunting regulations before utilizing a rangefinder in the field. The legality of rangefinders for hunting varies by location, with some regions allowing their use and others imposing restrictions. The laser technology used in a hunting rangefinder also needs to be more powerful, given that the distances involved are usually much larger than those on a golf course. A golf rangefinder, for instance, is designed to locate the nearest object – the flag, while a range finder for hunting is engineered to ignore the foreground, like branches or leaves, and instead focus on distant, potentially camouflaged targets such as an animal in the wild. While both golf and hunting rangefinders serve the primary function of distance measurement, they differ in some key aspects. Is there a Difference between a Golf Rangefinder and a Hunting Rangefinder? As technology advances, the laser range finder's accuracy, speed, and user-friendly features continue to evolve, making it an indispensable tool in any outdoorsman's arsenal. The practical applications of a laser rangefinder range from enhancing your hunting experience to refining your golf skills. This device, primarily employed in activities such as hunting and golfing, uses laser technology to accurately measure distances between the user and a specific target. In the realm of outdoor pursuits, a tool that has revolutionized precision and accuracy is the laser rangefinder. One such revolutionary innovation is the laser rangefinder, a tool that has revolutionized hunting. From enhancing our ability to navigate uncharted territories to improving the precision and accuracy of our imagery, technology has truly changed the way we interact with nature. In an age where technology has become an integral part of every aspect of our lives, it's no surprise that it has also made significant strides in outdoor activities. |
