Description:
The new Bluetooth audio spec has been finalized, and we expect to see it in Apple's next-gen AirPods Pro 2

FULL STORY ======================================================================

The Bluetooth Special Interest Group just announced it has wrapped up the final specifications for Bluetooth LE , a next-gen version of the Bluetooth audio spec promising wide-ranging performance enhancements for future headphones and earbuds like Apples forthcoming AirPods Pro 2 .

Whats different between the new Bluetooth LE spec and the older version? A
key upgrade is the new LC3 codec, which was designed to allow for better-sounding audio at lower data rates. According to the Bluetooth SIGs website, LC3 will bring tremendous flexibility to developers, allowing them
to make better design tradeoffs between key product attributes such as audio quality and power consumption. Auracast: Bluetooth audio sharing made easy

Another big change LE will bring is Auracast , a tech that can broadcast a synchronized audio stream to multiple headphones. With Auracast, a group of friends can simultaneously tune in a single stream, letting them all hear the same music, podcast, TikTok video, or whatever audio they want to listen to.

The benefits of Auracast extend to TV viewing as well, since Bluetooth LE transmitters can be integrated into TVs. This would let multiple viewers use headphones to watch the same program, with the volume adjusted for personal taste or Spatial Audio enabled, if desired. No need for a soundbar or other hardware-heavy external audio rig in this scenario.

The Bluetooth SIG has plans for Auracast that extend outside of the home as well. Video screens in public spaces could remain silent, with the accompanying audio broadcast out wirelessly for anyone with Bluetooth LE-capable headphones or earphones to access. And the process to make this happen would be similar to public Wi-Fi, where you use your phones settings
to log in and start streaming.

Other prime Auracast uses would be museum exhibits, where visitors could choose a broadcast of a curated tour, and concerts, where attendees could access a personal mix thats cleaner-sounding and easier to hear. Bluetooth LE and Auracast also have far-reaching implications for people with auditory challenges who might otherwise struggle to hear music, movie soundtracks, and various kinds of public-facing audio like airport announcements. Analysis: Bluetooth LE is here, but will it be in the AirPods Pro 2?

Apple tends to do things its own way, which is why were skeptical about lossless audio coming to the AirPods 2 . (That and the fact that there isnt any evidence to be tracked in the beta release of iOS 16 which would indicate otherwise.) This despite the fact that the full Apple Music library has been updated to lossless audio and subscribers can access the higher-resolution tracks at no extra cost.

But Apple products do support basic Bluetooth, and Bluetooth LE is the next-gen version of the technology, so it seems likely it will appear in forthcoming Apple products like the AirPods Pro 2.

Regardless of Apples plans, Bluetooth LE holds the promise to enhance
personal listening for all of us, and to bring a new level of flexibility via Auracast that allows for shared audio experiences and improved accessibility. Its hard to imagine any future AirPods variant not being part of that wave.
