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.

LDAC is great, but simply stating that the encoder is “open source” is quite misleading (while technically correct). The codec is owned by Sony and heavily licensed. It’s a savvy business move of Sony to make the encoder free to use though, so everyone else can support their standard while charging manufacturers who want to integrate it into their headphones.
If we want a really free and open high quality codec, we should push for opus support via bluetooth
Yes… I made double sure to mention ‘encoder’ between that.
Xiph really won the lossy codec scene with Opus and I transcoded all my junk to that format. Hitting (my personal) transparency on 128k vbr is flat out impressive and it warms my heart that corpos won’t have a reason to collect taxes for basic things like audio codec. However it’s a different story with bluetooth audio codec in which I hope will change.

Same here. I’ve left myself a bit of a safety margin at 144k vbr, but having my whole library at transparent quality AND portable size is very convenient.
Though, now that opus 1.4 is out I feel a bit of anxiety whether i should re-encode everything from flac->opus1.4
Which tool do you use to re-encode everything to opus ?
I tried with ffmpeg and it works but I had many issues with covers.
same as @denissimo@feddit.de I use foobar2000 + wine. ffmpeg is alright, but fb2k is very convenient (especially for replaygain tagging). Afterwards I usually give the files a Picard treatment to get proper tags + covers.

Check out Strawberry it’s essentially the Linux native version of foobar2000.
does it support foobar2000 plugins?
probably not, since those are windows dlls. So here’s a short list of what I’d want from a fb2k replacement:
- a UI plugin with the power and flexibility of Facets/Refacets
- browse library by folder structure OR tags (most only do one or the other)
- powerful query language to actually find what I’m looking for
- binaural stereo for headphones plugin
- convolver
- convert to opus and replaygain scanning
- DR Meter
- handle my >100k tracks library without constantly crashing or being incredibly slow
Most alternatives I’ve tried can’t even deliver on half of those.
Not anything to do with the LDAC codec but why does wireless headphones on windows suck. On linux (even a wm) I just turn on my headphones and it works, on windows every time I have to remove the device and add it back again

What about wireless headphones that don’t use bluetooth? I think I had some Logitech ones that did not use bluetooth. Are those a viable alternative to bluetooth on linux?

Huh, it works just fine for me. I have Samsung galaxy buds 2 pro. I don’t use it with my laptop often, but it’s seamless when I do.
Ldac is not actually that good, it’s actually fairly rare that LDAC beats out something like SBC XQ let alone AAC
EDIT: for elaboration, LDAC works at 3 main data rate ranges 990/909, 660/606 and 330/303. Ldac is only high res at the 990 range, and even at that range, it still often looses when pipewire is compiled against libfdk. keep in mind that it’s hard to get real numbers on LDAC because decoding is proprietary, meaning I had to disassemble headphones and connect those for verification, but typically AAC on supported headphones beat out 990kbps LDAC (which is hilarious btw considering LDAC can rarely actually work at 990kbps anyways) and both SBC-XQ and LC3Plus (both of which are usable with pipewire) regularly beat 660kbps LDAC.
TLDR LDAC is crap and SBC-XQ is typically more accurate and lower latency, and LC3Plus is even better then that. and if you have AAC compatible headphones assuming latency isnt a major issue (which you are using LDAC so it’s not) just use AAC, both fidelity and latency is better
EDIT: I should mention, it is known that vendors will tune codecs, I believe Valdikks article in habr briefly goes over this. so it’s very possible that tuning could mean that x codec, including LDAC could be the only good codec, however with how badly LDAC maintains 990kbps, I doubt it will make much of a difference
keep in mind that it’s hard to get real numbers on LDAC because decoding is proprietary
I used to think the same. But as it turns out, a decoder exists. Maybe some people don’t want anyone to know about it to keep the myths alive ;)
EDIT: Also, as a golden rule, whenever anyone sees the words High-Res in an audio context, they should immediately realize that they are being bullshitted.
just because a decoder exists doesnt mean it’s good and usable, and it also doesn’t mean you are legally allowed to use it without the appropriate licensing
Your skin glows quite beautifully, narc.
