It's loss-less, not loss-none

We really need someone other than Qualcomm & Apple to come up with lossless Bluetooth audio codecs.

TBF the whole Bluetooth audio situation is a complete mess

[–] conicalscientist@lemmy.world 0 points 6 days ago (2 children)

Well bluetooth doesn't carry enough bitrate to accomplish this. Besides. Apple won't and doesn't need to because their AAC encoder is superior. There is no other bluetooth codec that comes even close. Every codec that claims to be the best one yet is more marketing than anything.

Vendors reframed the narrative for SBC to be dog shit so they can push their own as cutting edge new tech. In reality SBC isn't that bad. The vendor codecs aren't that good. And Apple has some kind of secret sauce in their AAC encoder that results in really good quality reproduction of audio.

As far as I've seen most of the gimmicky codecs are spins of existing old technology. AAC itself is old too but at least one vendor Apple has focused on making their implementation good. We don't need another standard+1. We just need a common standard done well. If only Apple would open theirs.

Opus! It's a merge of a codec designed for speech (from Skype!) with one designed for high quality audio by Xiph (same people who made OGG/Vorbis).

Although it needs some more work on latency, it prefers to work on bigger frames but default than Bluetooth packets likes, but I've seen there's work on standardizing a version that fits Bluetooth. Google even has it implemented now on Pixel devices.

Fully free codec!

Correct. Qualcomm makes aptX

Wait, did Apple implement its own codec? I thought even the Airpods Max used AAC, which is lossy.

As for Qualcomm, only aptX Lossless is lossless and I'm not aware of many products supporting it (most supports aptX HD at most)

[–] cogman@lemmy.world 27 points 1 week ago (1 children)

Yeah, the problem (imo) isn't lossy v lossless. It's that the supported codecs are part of the Bluetooth standard and they were developed in like the 90s.

There are far better codecs out there and we can't use them without incompatible extensions on Bluetooth.

[–] Natanael@slrpnk.net 16 points 1 week ago (4 children)

There's a push for Opus now, it's the perfect codec for Bluetooth because it's a singular codec that fits the whole spectrum from low bandwidth speech to high quality audio, and it's fully free

On Windows, Alternative ADP2 driver provides LDAC support. It's a few bucks, but also the only option I know of.

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?

[–] forrgott@lemm.ee 30 points 1 week ago* (last edited 1 week ago)

I vote they choke indefinitely. But not to death; I want them to die of old age, spending decade upon decade choking endlessly.

I work in pro AV and so many companies do this. Wow, you say LOSSLESS video on a valens chip? Oh, you've never actually done a side-by-side conparison, have you..

Extron differentiates between lossless and "visually lossless" which I appreciate.

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.

Does this meme format / cat have a name? I was trying to find the raw version the other day and could not.

[–] rishado@lemmy.world 2 points 6 days ago (1 children)

I don't understand what's funny. It's developed with no competition, it's open source, it's definitely better than the current options out there and doesn't cost money. Is it just audio snobs in here? I consider myself somewhat snobby re:audio but even I use wireless headphones. Some grade A snobbery in this thread. LDAC is great. You're not convincing anyone to go back to wired headphones for day to day use

[–] frankenswine@lemmy.world 3 points 6 days ago

it's as simple as

loss-less vs. lossy

within only a few words of the main description of the thing - no judgement on the tech whatsoever (at least from my side)

[–] shifty@leminal.space 16 points 1 week ago

"On 17 September 2019, the Japan Audio Society (JAS) certified LDAC with their Hi-Res Audio Wireless certification."

Something something oxymoron. Bluetooth is trash, its why I still use wired whenever I can.

[–] ElectroLisa@lemmy.blahaj.zone 16 points 1 week ago (4 children)

To my knowledge it's lossless in CD quality only, in high-res modes it becomes lossy

[–] Yerbouti@sh.itjust.works 2 points 6 days ago

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.
