Share your audio, unmute your world, and hear your best — all of this is made possible by the newest innovation from Bluetooth® technology, Auracast™ broadcast audio.

Alongside the full specification release of Bluetooth LE Audio, the boundless potential of Auracast™ broadcast audio has made a significant impact upon the entire industry. Last month, the Bluetooth Special Interest Group (SIG) collaborated with several member companies to host The Auracast™ Experience at CEATEC 2023 in Shanghai, China and Tokyo, Japan. The Auracast™ Experience events  offer attendees the opportunity to experience Auracast™ broadcast audio first hand.


Visitors participated in several simulated scenarios: arriving at an airport for an international conference, navigating the airport terminal, and listening to keynote speeches at a public venue, all of which were enhanced by Auracast™ broadcast audio for sharing audio, unmuting, and listening at exceptional audio quality.

Similar to past events in Spain and Taiwan, participants here also had the opportunity to personally experience the entirely new broadcasting capability enabled by Auracast™ broadcast audio. Attendees were provided with Auracast™ compatible earbuds and a smartphone with an Auracast™ app for scanning, receiving, and playing Auracast™ broadcasts (in the near future, seamless bring-your-own-device usage will be increasingly accessible as more devices become compatible with Auracast™ broadcast audio).

While the smartphone and earbuds are paired, the smartphone is not actually the source of the audio. The audio source, the Auracast™ transmitter, is separate, and participants were able to select and receive various Auracast™ broadcasts through the app, akin to choosing from available Wi-Fi networks. With the smartphone in hand and earbuds on, visitors began their Auracast™ journey.

Unmute Silent Public Televisions

The event began with a hands-on experience, using Auracast™ broadcast audio to unmute silent TVs in a public setting. Participants visited an area designed to resemble the sports bar of an airport. In such bars it is common for multiple muted TV monitors to show various sports at once, but customers are unable to hear the commentary over the roar of the crowd. TVs equipped with Auracast™ broadcast audio deliver audio as Auracast™ transmitters, and event visitors were able to use the Auracast™ app on their smartphones to select the TV of their choice and listen via their Auracast™ compatible earbuds, then switch to the audio of another TV by selecting a new broadcast, without even a moment’s delay.

And this experience is not limited to sports bars. As the guide explained, possibilities include unmuting silent TVs in hospital waiting rooms, in gymnasiums, on trains, and more.

Enjoy Personal Audio Sharing at the Airport Without Missing Announcements From the Public Address System

After experiencing the Auracast™ equipped TVs, visitors then moved on to a re-creation of an airport boarding gate. There, they had the opportunity to experience how we will soon be able to share our audio with friends and family using Auracast™ broadcast audio. While waiting in the airport lounge with colleagues Dave and Lori, Dave asked them to join him as he watched a movie on his laptop, while Lori invited them to listen to music via her smartphone.

Participants received simultaneous invitations via the Auracast™ app. They scanned the available Auracast™ broadcasts and selected the one they wanted to hear, entering a password provided by the device’s owner. This allowed the audio being shared by Dave and Lori to stream directly into their earbuds.

During these personal audio sharing scenarios, only those who had the necessary passwords were able to participate, ensuring privacy while allowing more people to enjoy the same audio at once. Traditionally, the concept of sharing audio from a single source involved sharing the headphones themselves. With Auracast™ broadcast audio, however, you can listen to shared audio through your own headphones, making shared music much more accessible, even if you’re not physically close enough to share someone’s headphones.

Furthermore, by using the Auracast™ app on your smartphone to scan and receive Auracast™ broadcasts related to your boarding gate, you can receive important information being shared over the public address system directly into your personal headphones. Even while enjoying movies or music, if the airport’s announcement system is Auracast™ compatible, you can opt to receive those announcements directly and never again worry about missing important flight information.

Next on the tour, facilities like auditoriums can also add Auracast™ broadcast audio to their existing sound systems. This allows audiences to listen to high-quality, in-house broadcasts via their own Bluetooth®️ headphones or hearing aids.

Listen to Lectures at the Best Possible Sound Quality and in Multiple Languages

Finally, participants arrived at the lecture hall at the conference. You are never guaranteed a seat with ideal audio clarity, but with Auracast™ broadcast audio, participants were able to listen at the optimal volume to suit their needs via the highest audio quality possible on their own earbuds, regardless of where they were located.

If multi-lingual options are offered by the venue, participants can choose their preferred language.

Auracast™ broadcast audio also includes support for hearing aids and, combined with traditional hearing assistance measures, the result is a vast improvement in audio accessibility for all. This is particularly important as populations age, increasing the number of individuals experiencing hearing loss.

Retrofitting Existing Devices With Auracast™ Broadcast Audio

At The Auracast™ Experience, participants were also introduced to a USB dongle that can easily transform existing hardware, such as laptops, tablets, and smartphones, into Auracast™ transmitters. This means you can adopt Auracast™ broadcast audio without having to wait for new Auracast™ equipped transmitters to be released.

Participants at the event expressed surprise and high expectations for the new use cases that could become a reality via Auracast™ broadcast audio, sharing how they eagerly await the adoption of this technology by consumer devices and public spaces.

The experience of unmuting, sharing audio, and listening in the best possible sound quality as seen at The Auracast™ Experience is soon to become a part of everyday life, and a future where everyone can enjoy a richer audio experience through Auracast™ broadcast audio is right around the corner.

オーディオ共有、ミュート解除、最高の音で聴く-Bluetooth®︎の新しいイノベーション、Auracast™ ブロードキャスト オーディオは、このすべてを可能にします。

このAuracast ブロードキャスト オーディオが持つ限りない可能性は、2022年7月にBluetooth LE Audioの全仕様公開以来、業界全体に大きなインパクトをもたらしてきました。2023年10月、Bluetooth SIG(Special Interest Group)はメンバー企業数社をパートナーに、中国・上海のTech-G、そして日本・東京のCEATEC 2023で「Auracast™エクスペリエンス」を開催しました。Auracast™エクスペリエンスでは、参加者はAuracast™ ブロードキャスト オーディオの機能を直接体験できます。


来場者は、シナリオに沿って、いくつかのシミュレーションを体験します。国際会議出席のため空港に到着し、空港ターミナルで過ごし、講演会場で基調講演を聴く、そのすべての体験がAuracast™ ブロードキャスト オーディオによって強化され、オーディオ共有、ミュート解除、最高の音で聴くことができます。

スペイン、そして台湾での過去のイベントと同様、今回の参加者も、Auracast™ ブロードキャスト オーディオが実現する全く新しいブロードキャスト機能を実際に自分の耳で体験できました。各参加者に配られたのはAuracast™対応イヤホンと、Auracast™配信のスキャン、受信、再生ができるAuracast™アプリの入ったスマートフォンです(近い将来、より多くのデバイスがAuracast™  ブロードキャスト オーディオに対応することにより、各自が持参するデバイスでのシームレスな利用が実現します)。



イベントは、Auracast™ ブロードキャスト オーディオを使用し、公共の場にある無音テレビをミュート解除する体験からスタートします。参加者が訪れるのは、空港ターミナルのスポーツバーを模したエリアです。このようなバーでは、一般的に複数のテレビが並び、さまざまな試合が流れていますが、ミュートにされているため観客の歓声や解説実況を聞くことはできません。しかし、このバーではすべてのテレビがAuracast™ ブロードキャスト オーディオを追加装備し、Auracast™送信機として音声を配信しています。そのため参加者は、スマートフォンのAuracast™アプリを使用して視聴したいテレビを選び、音声配信を受信してAuracast™対応イヤホンで音声を聞くことができました。さらに別のテレビの音声への切り替えも、配信を選び直すだけで瞬時に可能です。

スポーツバーでAuracastTMを備えたテレビを体験した参加者は、次に空港の搭乗ゲートを模したスペースに移動します。そこでは、間もなく実現する、Auracast™ ブロードキャスト オーディオを利用した友人や家族とのオーディオ共有が体験できました。講演に同行する同僚のDave、Loriとの空港ラウンジでの待ち時間、参加者はDaveからはノートパソコンでの映画視聴に、Loriからはスマートフォンの音楽を一緒に聴こうと誘われます。


これらのパーソナルなオーディオ共有では、必要なパスワードを知る人だけが参加できるため、プライバシーは確保しながらも、より多くの人と一緒に同じ音源を楽しむことができます。これまで、一つの音源からオーディオを共有する場合には、ヘッドホンやイヤホン自体を共有する必要がありました。しかし、Auracast™ ブロードキャスト オーディオを使うことで、共有された音声を各自が自分のヘッドホンなどのデバイスで聞けるようになります。Auracast™があれば、たとえヘッドホンなどを分け合うほど親しい間柄でなくても、一緒に音楽を楽しめるシーンがぐっと身近になります。


次に体験する講堂などの施設でも、既存の音響設備にAuracast™ ブロードキャスト オーディオを追加で設置することが可能になります。それにより、観客や施設利用者は、各自のBluetooth®︎イヤホンや補聴器で高音質の場内放送が聞けるようになります。

ついに講演会場に到着です。このような場合には、よく聞こえる席に座れるとは限りません。しかしAuracast™ ブロードキャスト オーディオを使用することで、参加者は自分のイヤホンで、座る位置に関わらず、自身にとって最適な音量、最高の音で聴くことができました。


また、Auracast™ ブロードキャスト オーディオは補聴器対応を備えているため、従来の聴覚補助技術と組み合わせることによって、あらゆる人の音声アクセシビリティが大きく向上します。今後、社会の高齢化が進み、聴覚に障害を持つ人々が増加すると予測されるなか、この補聴器対応は極めて重要な意味を持ちます。

既存のデバイスにAuracast™ ブロードキャスト オーディオを追加装備

Auracast™エクスペリエンスでは、USBドングルを使用して、容易に既存のハードウェア(ノートパソコン、タブレット、スマートフォンなど)をAuracast送信機に変えられることが紹介されました。そうしたドングルを用いることで、新しいAuracast™送信機を備えたデバイスの登場を待つまでもなく、Auracast™ ブロードキャスト オーディオの実用が可能になります。

イベントの参加者からは、Auracast™ ブロードキャスト オーディオによって可能となった新しいユースケースに対する驚きや大きな期待と、この技術が搭載された消費者向け機器の普及や、公共の場への展開を待ち望む声が多く寄せられました。

Auracast™エクスペリエンスでのミュート解除、オーディオ共有、最高の音で聴く体験は、間もなく実生活でも可能になります。Auracast™ ブロードキャスト オーディオがもたらす、より豊かなオーディオ体験をあらゆる人が楽しめる未来は、すぐ目前まで来ています。
