As unfortunate as the naming misdirection is, I have to say: LDAC sounds significantly better (to me) than other Bluetooth codecs I have tried. It also works on Linux and android with no issues whatsoever. Open source is good.

I use it with a pair of Sony XM5's, which can also be used in wired mode, so you kind of get the best of both worlds.

at high signal strength LDAC should default to 990kbps.. which is kind of ridiculous since it's so high it's higher than some lossless codecs, like uncompressed 16-bit 48kHz. (which is higher than standard CD quality)

Uncompressed 16 bit 48KHz stereo is 1536 kbps, which is just slightly higher than what bluetooth 5 is capable of.

Oh I forgot about stereo, ha.

The bitrate is manually enforceable on Linux, too

*specifically using PipeWire

Pipewire or the pulseaduo Bluetooth codec add-on. The pipewire implementation seems to be mimicking the old pulseaudio plugin.

That's assuming raw PCM data, no compression (lossy or lossless) whatsoever.

LDAC can do lossless redbook audio (16 bit 44.1 KHz) at 990kbps. All other modes are lossy.
It's probably doing something much like FLAC- lossy encoder + residual corrections to ensure you get the original waveform back out, but with less bandwidth than raw PCM.

Are you using the Hifi Power Cable to? Very important to have

I highly doubt that. Do a proper ABx test (such as the one on digitalfeed.net) I have yet to meet someone who can pass the tests with a reasonable degree of accuracy.

You highly doubt my personal experience?

[–] ThomasLadder_69@lemmy.ml 0 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

Yes, because I have been an audio engineer for over two decades now. Show me someone who can reliably pass the iTunes test. Science does not care about your subjective personal experience.

Ok boomer

That would hurt my feelings if I wasn't a millennial lmao.

Seriously, though, your failure to even attempt to have a discussion tells me you have the discipline/intellect of a 14 y/o Ipad kid who learns everything from chatgpt.

Do you mean abx.digitalfeed.net?
