Been looking into LE Audio and saw that Bluetooth has been making a lot of progress for audio. However, if you look at LC3 codec, it can support 24 bit 48kHz stream, but it has a very low bit rate. It makes me wonder how a 24 bit 48kHz stream would be reduced by at least 6 times to wirelessly transfer the audio stream...
What info is lost in order to stream this "high-res" audio?
Has anyone done any work to improve audio over LE audio, and if so, please share your experience!

Wouldn't expect it to be up to CD quality, regardless of the sample rate. That is in part because of the compression and also in part because the receiver module may not be capable of being externally clocked. In that case, there is going to be jitter from whatever clock is included in the receiver module. That jitter can be attenuated with external ASRC processing, but its effects can't be completely eliminated.
of course it wouldn't, not at the bit rate it's going at (I believe it's 345 kbps?). I still wonder what data was deemed unworthy so it could be dropped before sending out?
Your last statement, ARSC processing, reading more about it. However, I still wonder about the quality loss.
Is it, for example, manipulating the loudness to appear loud (if it's over this threshold, cut in half), so that there is less info there?
There is a demo at: https://www.bluetooth.com/learn-about-bluetooth/feature-enhancements/le-audio/
However, it wouldn't play on my iphone16 in Safari. Does play on my laptop in Chrome browser.
Have to be careful though when comparing to so-called lossless, which for streaming services may actually be 192kbps.
