What’s the Range of Auracast™ Broadcast Audio?

Auracast™ Broadcast Audio ~100 meters: Mains powered Auracast™ public transmitters broadcasting a one-way audio broadcast can turn their transmit power up and will contain a more sophisticated antenna, greatly expanding their coverage area.

Paired Audio Connection ~10 meters: Bluetooth® Classic audio solutions have long been designed for a source and sink device to establish a paired, two-way connection within a small, personal coverage area.

Can You Add Auracast™ Support to Existing Devices?

Yes. A complete suite of retrofit solutions is in development. Auracast™ dongles and streamers for phones, tablets, laptops, and TVs will be coming to market, transforming existing audio source devices into Auracast™ transmitters.

So too will plug-in adapters for commercial sound and public address systems, allowing public locations to turn their venue into an Auracast™ location using their existing sound systems.

Other retrofit solutions including Auracast™️ neck loops, standalone assistants, and smartphone applications from device manufacturers will help round out the retrofit ecosystem and enable users with legacy receiver devices to experience Auracast™️ sooner than later.

Is the Number of Auracast™ Receivers Really Unlimited?

Yes, really. Auracast™ broadcasts function in a similar way to standard FM radio broadcasts. There is no connection between the transmitter and receiver, and the transmitter is completely unaware of the number of devices that have tuned in to the broadcast. In this way, the number of potential receivers truly is unlimited.

FM Radio Transmitter: An FM transmitter broadcasts a single audio signal that any number of FM receivers can tune into.

Auracast™ Transmitter: An Auracast™ transmitter broadcasts a single audio signal that any number of in-range Auracast™ receivers can join.

Auracast™ ブロードキャスト オーディオは昨年、オーディオ業界において大きな話題となりました。世界各地を巡回するインタラクティブな展示イベントAuracast™ Experienceを通じ、製品開発者、メディア、アナリストをはじめ多くの人々が、オーディオ共有、ミュート解除、最高の音で聴くことを可能にし、人や環境との関りを豊かにして日々の生活と人生を変えるようなオーディオ体験を提供するAuracast™ ブロードキャスト オーディオを体験しました。

各地のイベントを通じて、いくつかの質問が繰り返し寄せられました。以下は、Auracast™ ブロードキャスト オーディオに関して最も多く寄せられた3つの質問と、その回答です。

Auracast Conference 1 1200x628 Logo

Auracast™ ブロードキャスト オーディオの通信距離はどのくらいですか?

Auracast™ ブロードキャスト オーディオ 最大で約100m: 
コンセントから電源を取るAuracast™の業務用送信機で一方向の音声配信のみを行う場合、出力を上げることができ、より高度なアンテナを備えられるため、通信距離を大きく拡大できます。

ペアリングによるオーディオ接続 最大で約10m: 
Bluetooth® Classicを使用する従来のオーディオソリューションは、個人使用の小規模な範囲内でソースデバイスとシンクデバイスがペアリング接続を確立し、双方向通信を行うことを想定して設計されています。

既存デバイスにAuracast™対応を追加することは可能ですか?

はい。すべてがそろった後付け用ソリューションの開発が進められています。携帯電話、タブレット、ノートパソコン、テレビなどに使用できるAuracast™ドングルやストリーマーがやがて市場に登場し、既存のオーディオソースデバイスをAuracast™送信機に変えられるようになります。

同様に業務用音響・場内放送システム用のプラグインアダプタも登場し、公共の場の既存の音響システムを使用して施設をAuracast™対応に変えられるようになるでしょう。

デバイスメーカーからはAuracast™️のネックループ、スタンドアロン型のアシスタント、スマートフォンのアプリケーションなどが提供され、後付けソリューションのエコシステムを補完していきます。これらにより、Auracast™️非対応の受信デバイスを使用するユーザーでも、より早期にAuracast™️を体験できるようになる見通しです。

Auracast™受信機の数は本当に無制限ですか?

はい、本当に無制限です。Auracast™の配信機能は、通常のFMラジオ放送の方法に類似しています。送信機と受信機との間には接続がなく、送信機側では配信を受信しているデバイスの数には一切関知しません。このため、受信できるデバイスの数は全くの無制限なのです。

FMラジオ送信機: 1台のFM送信機は一つのオーディオ信号を配信し、FM受信機は周波数に合わせることで台数に制限なく受信できます。

Auracast™送信機: 1台のAuracast™送信機は一つのオーディオ信号を配信し、受信範囲内にあるAuracast™受信機であれば台数に制限なく放送に参加し受信できます。
