AptX adaptive is an adpcm codec, so there is no artifact except for a higher noise level.
At 460kbps it's very very similar to LDAC at 990kbps.
It's also unlike AAC a truly adaptive codec.
If you really need it AptX also has a lossless mode iirc.
The best codec would obviously be to just use Opus, yeah. But AptX adaptive pretty much solves Bluetooth audio.
- out_of_protocol 5y agoNo idea how it supposed to work in theory, in practice every device combo i tried works noticably worse with AptX (than LDAC, even non-990 one). Don't have any device capable of AptX lossless. Re: solve - as long as there are licensing issues, it can't solve BT Audio even if it was such great codec P.S. Random link from google with measurements of some actual device using AptX, AAC, LDAC https://www.audiosciencereview.com/forum/index.php?threads/topping-bc3-review-bluetooth-receiver-bt-codecs.23740/ https://www.audiosciencereview.com/forum/index.php?threads/t...
- spookthesunset 5y agoHow are you able to know which codec is being used over the Bluetooth link?
- out_of_protocol 5y agoE.g. my device (Fiio BTR5) tells me on its builtin display. Also for LDAC there's separate toggle in UI. Also Developer Tools stuff
- sudosysgen 5y agoAgain, that is AptX, not AptX HD or AptX adaptive. I don't think the lossless mode is in any product yet.
