Many lossless codecs are lossy codecs + residual encoders. For example FLAC has predictor(lossy codec) + residual.
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.
I highly doubt that. Do a proper ABx test (such as the one on digitalfeed.xyz) I have yet to meet someone who can pass the tests with a reasonable degree of accuracy.
You highly doubt my personal experience?
Do you mean abx.digitalfeed.net?
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)
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.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.
Are you using the Hifi Power Cable to? Very important to have
Ah, misleading use of terminology that indicates one thing, but will win in court even if it actually means, or can later be said to mean, another.
I hope those involved in helping companies win these lawsuits choke on bones from food sold as boneless. Because that won a court case after “boneless” was redefined as a cooking method.
I don’t want them to choke to death. Just a little lesson, you know?
I vote they choke indefinitely. But not to death; I want them to die of old age, spending decade upon decade choking endlessly.
I remember when unlimited minutes plans for cell phones meant 300 minutes.
Or when Comcast had unlimited downloads which was capped at 2 TB.
These shitty companies know exactly what they are doing.
I had an “unlimited” plan with a cell company - I took them at their word and downloaded gobs of stuff. Got shut down in a week.
Of course it’s Ohio!
Does this meme format / cat have a name? I was trying to find the raw version the other day and could not.
“Cat looks inside”
Thanks!
To my knowledge it’s lossless in CD quality only, in high-res modes it becomes lossy
FLAC is a lossless compression format. It will reduce file size but keeps the audio quality. So-called “high-res” format on streaming platform like spotify (mandatory fuck spotify here) are usually mp3 320kbps so heavily compressed and lossy, indeed.
It’s nearly lossess if you can connect and maintain a 990kbps connection, but it still doesn’t have enough bandwidth to do it truly lossless. I think it would require 1411kpbs to be actually lossless. It is still better than any codec I know of for bluetooth as far as that does, but bluetooth just kinda sucks for that sort of application.
1411 kbps before compression. FLACs can go as low as 200 kbps based on the content of a file
Interesting. If that is so, then I am surprised that neither actually support actual lossless at that res without blowing up the noise floor.
My favorite is most people are listening to already lossy compressed music that gets decoded and then recompressed in another lossy manner… I miss my cable sometimes.
In the end, I found I don’t really care that much, since lossy Bluetooth works well enough for earbuds on the go, and good old cables are still available for more serious listening.
Plus, the truth is that most people can’t tell the difference between lossy and lossless without doing A/B testing, and some can’t tell even with that
Compression is lossy.
So when you zip some files and then unzip them, some of the bytes are missing? Really?!
If nothing is lost, what did you compress away? Decompression is magic, I ain’t gotta explain shit
you compressed away redundant data, 1111111000000000011111111 -> (1x7)(0x10)(1x8)
Keep your magic ways to yourself, wizard
If you want the magic explained, here’s a start: https://en.wikipedia.org/wiki/Lempel%E2%80%93Ziv%E2%80%93Welch
Newer fractional arithmetic encoding can get crazy
Some compression is lossy
