From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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

[–] madeindjs@lemmy.ml 0 points 1 year ago (1 children)

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.

[–] denissimo@feddit.de 0 points 1 year ago

I use foobar2k via wine. Yes, you may stone me. Tip: You will save heaps of space by not embedding the cover on each file, just put a cover.jpg in the albums folder, virtually any player will pick it up.

Isn't the new default codec in BLE Audio LC3 free and open and high quality? And it's required for BLE Audio support, so there will be more and more devices that support it.

I recommend you all to switch to Pipewire. Most bluethooth problems are fixed.

[–] Simplesyrup@lemmy.ml 0 points 1 year ago (1 children)

Isn't that standard on most linux systems?

[–] fugepe@lemmy.ml 0 points 1 year ago (1 children)

if your distro is not using Pipewire youre using a shitty one

[–] Simplesyrup@lemmy.ml 0 points 1 year ago (1 children)

I'm so confused, please don't confused a new linux user it doesn't help me

[–] twei@feddit.de 0 points 1 year ago

You can find out if you have pipewire or pulseaudio by using pactl info | grep "Server Name"

[–] nottheengineer@feddit.de 0 points 1 year ago (1 children)

Sony did drop the ball with LDAC quite quickly, it could've been the new standard.

But with the release of the WH-1000XM3s (or was it the 4s?) they basically made most of the selling points incompatible with LDAC, so now almost no one uses it anymore.

[–] denissimo@feddit.de 0 points 1 year ago (1 children)

Yes, LDAC and multipoint do not mix hence I'm looking forward to LC3plus that replaces it. To be fair it's not a big issue to roll back to AAC or even SBC to use multipoint, because you probably aren't gonna notice a difference when you don't listen to high res apps like Tidal. It also should be known that a good codec does not fix mediocre drivers and/or chips. Regardless, Linux shines in letting you use a feature you did pony up for. :)

[–] oeightsix@lemmy.nz 0 points 1 year ago (1 children)

LDAC and Multipoint do in fact mix, just not on Sony products.

[–] denissimo@feddit.de 0 points 1 year ago

I see, so Edifier and Soundcore shall do some homework as well: LDAC and multi point don't work there either.

Shame about headsets though - has anyone been able to get the mic to work without the audio quality dropping to trash? It is a shame to have to pick between good quality audio and the ability to use your mic.

[–] denissimo@feddit.de 0 points 1 year ago* (last edited 1 year ago)

I feel you there. Personally I just use the earbuds as output and the integrated laptop mic as input. Bluetooth really just doesn't shine in that regard. However if you're on Desktop and want everything to happen on a headset, not earbuds x wired stand mic, you should look into things like HyperX Cloud 2 Wireless that employ a USB dongle instead.

[–] aksdb@feddit.de 0 points 1 year ago (1 children)

I ended up buying JBL Quantum TWS in-ears because they also include a USB-C dongle that speaks their own protocol which allows lowlatency duplex audio. Perfect for audio calls and even gaming. Plus, I don't need to pair them with every device, I can just bring the dongle. (They can also be paired with Bluetooth and you can switch between dongle and BT whenever you want.)

[–] amenotef@lemmy.world 0 points 1 year ago (1 children)

This is interesting. So these have the "non BT 2.4Ghz" protocol that you generally find in the huge wireless gaming headset?

Ive been looking for a wireless headset that has the low duplex latency of wireless gaming headset, but in a smaller package. Something like the "Microsoft Modern Wireless Headset" but with 2.4Ghz non BT. And I couldn't find yet something like this.

[–] aksdb@feddit.de 0 points 1 year ago (1 children)

Yes, exactly.

Actually "Gaming" was exactly the keyword that finally made me find these things. Looking for "normal" headsets/in-ears you can find some that also claim to be optimized for conferences and of course they also claim "low latency", but looking deeper the best they typically have are aptX-LL or something, which does shit when in duplex mode (unless yours and their bluetooth stack allow some hackery like Faststream). But the gaming-optimized ones typically offer real low latency.

Downside of in-ears is obviously the battery lifetime. I think I need to quick-charge them every 3h. But it's not often a problem, since most of the time I put them in their charging box during a short (5 minutes or so) break which is enough to boost them long enough that I don't even notice the battery through out a longer session. Upside - which I wanted them for is - that I don't have a large headset covering my ears and pressing on my head.

[–] amenotef@lemmy.world 0 points 1 year ago* (last edited 1 year ago) (1 children)

These could be nice upgrade for my Pixel Buds A series. I'm using them for Teams (low latency bad quality). (Not just music high latency high quality).

However, what I really also want to have are gaming headsets (with the long microphone and low latency) that are a bit more low profile and not huge.

At first I thought it was a matter of physics, but after seeing 2.4Ghz low latency in these tiny earbuds I guess it's possible.

Can't believe low profile on-ear headsets are not popular. They are all over the ear or huge.

And as you said the ones they generally make for teams sucks with BT high duplex latency.

[–] aksdb@feddit.de 0 points 1 year ago

Overear wireless gaming headsets should be easier to find. Logitech for example builds them for ages. I also had foldable business headphones from Logitech that have their own dongle and bluetooth support.

[–] biscuitsofdeath@lemmy.ml 0 points 1 year ago (1 children)

I'm still wondering how to make my headphones work on pop os without crackling

[–] efff@lemmy.world 0 points 1 year ago (1 children)

You will not believe this. Solution was adding a line in some config file.

[–] Holzkohlen@feddit.de 0 points 1 year ago

Are you thinking of the standby timeout? Cause I get static on my speakers on any and all distros when no audio is playing. It always happens after 5 seconds of silence. Kinda infuriating that I have to do this on EVERY SINGLE DAMN INSTALL.

For Pulseaudio:
Quickfix (until reboot):

sudo su
echo 0 > /sys/module/snd_hda_intel/parameters/power_save

permanent fix is to add the line:
options snd-hda-intel power_save=0
to the file /etc/modprobe.d/alsa-base.conf

For pipewire:
create folder /etc/wireplumber/main.lua.d/ if it does not exist
if you had to create it yourself just copy over the file from /usr/share/wireplumber/main.lua.d/50-alsa-config.lua
otherwise it probably is there already then just edit it
pretty much at the bottom there is a line that says "session.suspend-timout-seconds"
uncomment it and set its value to 0
then reboot
