The LE Audio specifications were recently completed, and with that milestone comes exciting new capabilities, including the ability to broadcast audio using Bluetooth® technology. This new LE Audio feature enables an audio transmitter to broadcast to an unlimited number of nearby Bluetooth audio receivers and opens significant opportunities for innovation, including a powerful new capability, Auracast™ broadcast audio.

“Bluetooth technology is extending its track record of innovation with the launch of Auracast™ broadcast audio,” said Peter Liu, System Architect, Pixel Ecosystem Products at Google. “We are proud to work with the Bluetooth SIG and are excited to see this capability provide consumers with new, imaginative ways to connect with each other and hear their world.”

Now that the specs are out, it is a good time to look at how they might impact audio development for audio developers.

Qualify & Branding Your Audio Innovation

Like all products that incorporate Bluetooth® technology, products that include support for Auracast™ broadcast audio must complete the Bluetooth Qualification Process using Launch Studio. The Bluetooth Qualification Process promotes global product interoperability and helps Bluetooth SIG member companies ensure their products comply with licensing requirements for the use of the Bluetooth® trademarks in conjunction with their products, including the Auracast™ trademarks.

Product developers who qualify their products to the Public Broadcast Profile (PBP) specification through the Bluetooth Qualification Process and meet the additional requirements of use that are detailed in the Brand Guide for Bluetooth Trademarks can be licensed to use the Auracast™ trademarks in association with those qualified products. In addition to detailing the licensing requirements for using the Auracast trademarks, the Brand Guide for Bluetooth Trademarks (page 18) also provides rules and guidelines when applying them to products, websites, and supporting promotional materials.

For products that indicate they implement and meet the requirements for the PBS role as defined in the PBP Specification must also meet the following requirements to use the Auracast Trademarks:

  • The product must be configurable by the end user to broadcast a Standard Quality Public Broadcast Audio stream (as defined in the PBP Specification) within an Auracast™ broadcast. An “Auracast™ Broadcast” means an audio broadcast using Bluetooth® wireless
    technology that complies with the PBP Specification, including transmission of the Public Broadcast Announcement.
  • If the product is marketed for use within a Public Location (where “Public Location” means any public, private, or commercial venue, building, mode of transportation, or open space), the product’s default setting must be set to broadcast a Standard Quality Public Broadcast Audio stream when the product is configured to transmit an Auracast™ broadcast. Products marketed for a Public Location include, but are not limited to, public address systems, assistive listening systems, and commercial televisions.
