According to information spotted by the 9to5Google site, the Pixel 7 and Pixel 7 Pro will benefit from a host of new features for wireless headphones and earphones thanks to the arrival of Bluetooth LE Audio.
In the coming months, Google plans to launch its next high-end smartphones. Two models are thus expected: the Google Pixel 7 and the Google Pixel 7 Pro. Although the firm has already announced its launch at the spring Google I/O conference, we still do not know its full features.
However, the site 9to5Google, specializing in Google news, has obtained particularly interesting information in the field of wireless audio for these two smartphones. The American site has detected an Android code change line, specifically regarding the Pixel 7 and 7 Pro, but also the future Google Pixel 7a, expected in spring 2023.
This change concerns support for Bluetooth LE Audio. We already know that Google plans to implement this new specification within Android 13. However, to take advantage of it, smartphones must still be equipped with compatible components, which is not the case with the Pixel 6, 6 Pro and 6a already released by the manufacturer. .
In the lines of code marked with 9to5Googleone of the Android developers reports that Bluetooth LE Audio will be integrated into the “p22/p23a”i.e. Pixel smartphones scheduled for Fall 2022 and Spring 2023. So it should be Google Pixel 7, 7 Pro and 7a.
A new higher quality LC3 codec
To understand what the benefits of Bluetooth LE Audio are, you first need to understand how classic Bluetooth audio works. It is based on the A2DP profile and the specially compressive SBC Bluetooth audio codec. So much so that, for years, manufacturers have continued to develop more efficient codecs for better audio quality. Naturally, we think of aptX or LDAC, but also Samsung’s LHDC or SSC.
Bluetooth LE Audio will allow you to take advantage of a new codec natively built into the specification and enable better audio quality in Bit rate the same: LC3, for low complexity communications codec. If the SBC codec used so far could also vary its Bit rate from 128 to 345 kbps depending on the stability of the signal, the LC3 will have more headroom with values of 64, 96, 128, 192, 248 kbps or 345 kbps. Also, even at a lower bitrate, the quality offered should still be better than when using the SBC codec at 128 kbps.
While the SBC is limited to 16-bit depth, varying the sound level by 65,536 volume levels, the LC3 will also be able to go up to 32-bit depth for 4,294,967,295 levels, thus promising more sound dynamics.
Auracast, multi-stream and hearing aids
In addition to integrating this new audio codec for better quality, Bluetooth LE Audio also includes three other features: Auracast, multi-stream, and hearing aid compatibility.
On the Auracast side, this time it’s about allowing wireless headphones or earphones to automatically connect multiple headphones or pairs of headphones to the same source. A feature that could be practical for example in guided tours of museums. The Multi-Stream Audio feature will allow multiple channels to be streamed directly from one source, such as a smartphone, to headphones or earphones. This feature should ensure, in the case of wireless headphones, that each headphone independently receives its own audio channel.
Finally, on the hearing aid side, Bluetooth LE Audio will make it easier to manage your hearing aids by allowing them to connect to different sources, such as a computer, smartphone or TV.
More and more helmets or headphones launched on the market are advertised as compatible with Bluetooth LE Audio. However, in the absence of a compatible smartphone, these features are not yet implemented. With the arrival of the Pixel 7 and Pixel 7 Pro in the coming weeks, we should finally be entitled to the first smartphones with this new specification. As a reminder, the two smartphones could be presented in detail in early October.
