According to a new report which surfaced in China, all Xiaomi-branded smartphones which are running Android Oreo will receive support for LDAC in the future. This info is based on the fact that all development build of Android Oreo for Xiaomi smartphones do come with LDAC support, so it's safe to assume that stable builds of MIUI will get it in the future, though different phones will get such support in different times, of course, as the company will not release the same update to all the devices at the same time.
So, some of you are probably wondering what is LDAC. Well, LDAC stands for Lossy Audio Codec, and it's being developed by Sony for use in Bluetooth devices. LDAC arrived with Android Oreo as part of AOSP (Android Open Source Project), and it has a considerably higher bitrate than was previously possible with Bluetooth audio. Thanks to LDAC, it's possible to transfer audio data at a bitrate of 990kbps, which is quite high considering that most streaming services are still limited to 320kbps. Now, you will probably be able to listen to really high-end audio on your smartphone using a pair of headphones, though do keep in mind that you will need a really high-end pair of headphones in order to do that, as most of them will not be able to output audio at such high bitrates.
Now, many people compared LDAC to Qualcomm's aptX and aptX HD. LDAC, unlike aptX, does not top out at 576kbps (aptX HD). It is worth saying that LDAC probably doesn't matter for most of you, as most of you don't really have a really high-end pair of headphones, nor do you care about your audio being outputted as such high bitrates, mainly because 320kbps sounds great, and most of you are using streaming services as it is. Mp3 files in general top out at 320kbps, though LDAC will come in useful for those of you who have a collection of songs in FLAC, as FLAC does not top out at 320kbps, not even close. So, all in all, if you're an audiophile, you'll probably welcome the 'LDAC update' that is coming to Xiaomi's handsets.
