Thank you!

It's so hard to get an answer to this question.

Yes, LE Audio will indeed improve the noticeably lower audio quality issue which was present for the HFP and HSP Bluetooth Classic profiles. LE Audio is a completely new audio framework with all new profiles and services that improve on the existing use-cases, as well as adding many new ones. You can read more about the new profiles and services in the Generic Audio Framework Specification section posted by Bluetooth SIG themselves just last week!

Hello Burhan. The numbers we present here are sourced from Bluetooth SIG themselves www.bluetooth.com/learn-about-bluetooth/recent-enhancements/le-audio/ , which in turn comes from this paper secure.aes.org/forum/pubs/conventions/?elib=21084 where you can see that it is indeed the OPUS v1.3 that is being used in the comparison. However, the focus in our presentation is on the comparison between the LC3 and the SBC, since the SBC is the mandatory codec for the Bluetooth Classic standard, while the LC3 is the mandatory codec for the new LE Audio standard - which makes it natural to compare the two. If you would like to read more about the LC3 you could take a look at the materials references in this blogpost as well: devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/low-energy-audio-is-finally-here
