For context, LDAC is one of the few wireless audio codecs stamped Hi-Res by the Japan Audio Society and its encoder is open source since Android 8, so you can see just how long Windows is sleeping on this. I’m excited about the incoming next gen called LC3plus, my next pair is definitely gonna have that.
at 990/909 kbps bluetooth can hardly hold that bitrate unless you have really good conditions so much as walking down a stream will bring it down to 660kbps
and yes, AAC does have better fidelity, at 320kbps AAC and Opus are largely transparent to 90% of users keep in mind I am comparing fdkaac on Pipewire, NOT android, this is an important distinction since they were testing android, and you can see here how spotty AAC is on android https://www.soundguys.com/the-ultimate-guide-to-bluetooth-headphones-aac-20296/
I am talking specifcally about linux in this context
EDIT: also it’s not about being an apple fanboy, Opus is largely just as good, marginally better, but no headphones support them, if you want you can even compile pipewire with higher bitrate limits on opus for stereo, (IIRC the pro profile can override it? cant remember but code is here https://gitlab.freedesktop.org/pipewire/pipewire/-/blob/master/spa/plugins/bluez5/a2dp-codec-opus.c)
opus is transparent for all the the most intense songs by 160kbps, and for regular stuff you’d hear on the radio it’s transparent anywhere from 96kbps-128kbps
while this is the case for a lot of songs, a lot of instrument heavy songs can cause noticeable artifacting for some people. It’s pretty rare, but in the end, it’s not like we are storing the media so why care? we can do upto 320kbps for a stereo stream, and as far as I am aware, it’s not like there are any detriments to doing so (maybe marginally higher power usage I guess).
I wasn’t able to myself, but I did have a friend test the snug space endless lane, and they were able to fairly reliably tell the difference between 128kbps and the original rip. the In the moonlight track too has a high pitch… triangle maybe? that can exhibit artifact too.
so like, yeah, but we have the 320kbps we can work with, so like, why not?
