IFA, one of the world’s longest-running exhibitions, has an illustrious history of showcasing cutting-edge technology in consumer electronics. This year, at IFA 2024, media and analysts from all over the world had an opportunity to participate in an immersive Bluetooth® audio event, The Auracast™ Experience.
For nearly two years, The Auracast™ Experience has toured the globe, offering attendees the chance to familiarize themselves with Auracast™ broadcast audio firsthand. This year at IFA, Auracast™ broadcast audio won a Best in Show award, and a steady stream of media, analysts, and influencers toured The Auracast™ Experience, checking out the product showcase.
Auracast™ broadcast audio is a new Bluetooth® capability that enables an audio transmitter to broadcast audio to an unlimited number of receivers. A transmitter can be a smartphone, laptop, TV, or even a public address or sound system, and receivers are headphones, speakers, earbuds, or even hearing aids. Auracast™ broadcast audio will enable exciting new audio experiences that will enhance the way we engage with each other and the world around us.
At IFA 2024, the Bluetooth Special Interest Group (SIG) – in collaboration with several member companies like JBL, Listen Technologies, Ampetronic, Audeara, Intel, Qualcomm, Hisense, NTT Sonority, Xiaomi, Samsung, GN ReSound, Nordic Semiconductor, Sennheiser, Sony, and more– showcased a range of new Auracast™ products that will soon be commercially available to help you share your audio, unmute your world, and hear your best in the places you go.
“Collaborating with the Bluetooth SIG on Auracast™ broadcast audio has been transformative for us as an audio company,” said Carsten Olesen, president of consumer audio at JBL. “Their innovative broadcast solutions and commitment to excellence have enhanced our product offerings and elevated the overall audio experience for our customers.”
The Auracast™ Experience at IFA 2024
The Auracast™ Experience is a global series of immersive events that allow visitors to see firsthand how Auracast™ broadcast audio will help our world sound better. Similar to the demonstrations given at CES 2024, Tech-G, CEATEC, Computex Taipei, Mobile World Congress, and more – visitors took part in several simulated Auracast™ scenarios: arriving at an airport to travel to an international conference, navigating the airport terminal, and listening to keynote speeches at a public venue.
However, unique from past events, all devices showcased at The Auracast™ Experience at IFA 2024 were real-world Auracast™ products from major manufacturers that are either currently commercially available or soon will be.
One particular product of interest for many visitors was the JBL speakers – a coordinated set of Auracast™ speakers set up on The Auracast™ Experience tour to provide a soundtrack for the product showcase. These speakers transmitted and received Auracast™ broadcasts to help illustrate the ultra-low latency of Auracast™ broadcast audio, showcasing how the speakers could be synced in a wide range of environments – from the home to a party on the beach.
The Auracast™ Experience
The Auracast™ Experience is a global series of immersive demonstration events that allow visitors to experience some of the ways Auracast™ broadcast audio will help our world sound better.
Unmuting Silent TVs at an Airport Sports Bar
The Aurcast™ Experience at IFA began with a hands-on demonstration of Auracast™ broadcast audio in an airport sports bar. Imagine arriving early at the airport and deciding to go to the sports bar in the terminal to watch a game. As is often the case, the bar had multiple TVs showing different games, and the sound was turned off on all of them – participants could watch the game, but they couldn’t hear it.
With Auracast™ broadcast audio, visitors had a chance to experience unmuting the TVs in the sports bar. Attendees were able to choose between two different TVs broadcasting different games. The first TV, an Auracast™ TV from Hisense, broadcasted audio directly to the listener’s earbuds. The second TV was a legacy model equipped with an Auracast™ streamer from Resound (currently available). With the Resound TV Streamer+, participants could seamlessly tune into the audio from the second TV as well.
This experience is not limited to sports bars. Silent TVs in hospital waiting rooms, gymnasiums, trains, and more are all ideal spaces where Auracast™ broadcast audio can enhance the watching experience. And while TV manufacturers continue to work on adding Auracast™ broadcast audio to their TVs, streamers like the Resound TV Streamer+ can turn an existing TV into an Auracast™ transmitter, even while we wait for native support in TVs.
Sharing Audio and Receiving Announcements at the Airport Gate
At the airport gate demonstrations, visitors got to participate in two Auracast™ experiences: sharing audio from a laptop and phone and hearing gate announcements broadcasted to their earbuds.
First, while waiting in the airport lounge, attendees were invited to watch a movie together on a friend’s laptop or listen to music on another friend’s phone. For this personal audio-sharing scenario, only those with the necessary passwords were able to listen in (much in the same way we experience accessing public Wi-Fi networks or personal Wi-Fi hotspots) – ensuring privacy while allowing more people to enjoy the same audio at once, each on their own earbuds. Visitors could even effortlessly switch audio between the two devices without any delay in audio reception or clarity.
The laptop and smartphone used in this demonstration included the capability to broadcast an Auracast™ signal, but, like the second TV in the airport sports bar demo, Auracast™ dongles can be plugged into existing laptops, tablets, and smartphones to transform them into Auracast™ transmitters. Similar devices are even being developed for commercial sound systems so public venues can potentially turn their location into an Auracast™ location using an existing sound system.
Second, thanks to the inclusion of an Ampetronic Auracast™ transmitter (coming soon to market), visitors who opted into the broadcast were able to hear airport announcements directly in their earbuds, even while enjoying movies or music. This much-needed advancement alleviates the worry of missing important flight information. It is even more impactful for hearing-aid users; receiving direct-to-ear audio in noisy public locations can be life changing. In this way, Auracast™ broadcast audio has the potential to be the next generation of assistive listening systems, increasing audio accessibility and helping people with all levels of hearing health to hear their best.
Hearing Your Best in an Auditorium
Participants then arrived at the lecture hall for the conference. In this simulated scenario, visitors show up a few minutes late and can only find seating at the back of the auditorium where, often, it can be difficult to hear the lecture. However, since this auditorium is set up to support Auracast™ broadcast audio, attendees were able to listen at the optimal volume to suit their needs via the highest audio quality available on their own earbuds, no matter where in the auditorium they were seated.
Lastly, at this point in the tour, attendees had the opportunity to hear the audio from their guide’s microphone in their earbuds. Watching the tour guide speak while hearing that person’s voice via the earbuds, participants heard no perceptible lag or audio delay. Extremely low latency, like what these visitors experienced, is the only way to avoid an echo effect or lip-sync problems.
Those on the tour familiar with loop systems also had an opportunity to see how Auracast™ broadcast audio coexists with and can expand the capability of loop systems. A neck loop plugged into an Auracast™ receiver from Listen Technologies can enable broader deployment and increased availability of assistive listening in public locations, promoting better living through better hearing for everyone. Neck loops can be retrofit options for hearing instrument users, allowing them to experience Auracast™ broadcast audio even if they do not yet have Auracast™ enabled hearing aids.
Finding an Auracast™ Broadcast
Soon, whenever you visit a venue or location that offers Auracast™ broadcast audio, you will be able to use your smartphone to scan for Auracast™ broadcasts in the building – similar to how public Wi-Fi networks are detected. And now, Google has provided a way for venues and businesses to let visitors know whether Auracast™ broadcast audio is available at their location even before visitors arrive.
