as the person who pushed for the alpine core team (now TSC) to adopt a policy of rejecting telemetry features in alpine-packaged software, i have opinions on flathub 🙃

mostly i am concerned that pushing users to use vendor-provided builds distributed on flathub may be exposing users to harmful software misfeatures like telemetry in ways that they would not if those same users installed packages from a distribution which patches out these misfeatures as a matter of policy

i wish that flathub would explicitly ban telemetry and check for telemetry features during their review processes. i would be more likely to recommend flatpak in more cases if they did.

@falktx Dude! This looks amazing! I just bought a bass recently so I'm watching with interest. :) Steve from the open source musician podcast days! Good to see your face again in the video. :)

Why can't Windows be normal?

The USB audio interface feature works pretty much as per standard on Linux and macOS, but on Windows it's a damn mess.

When investigating issues it was funny to see this written on an alternative usb audio implementation:

> Microsoft Windows USB Audio 2.0 driver available since Windows 10, release 1703 expects Full-Speed explicit feedback endpoint wMaxPacketSize to be equal 4, which violates the USB 2.0 Specification.

and other similar things...

🤦‍♂️ 😡

any TU Berlin students here? there's a brand new Open Source Hardware seminar this semester (MNT will also make an appearance if it happens) and so far only 3 students registered! they need at least 5 to make it work, so if you're interested or know potential candidates at TU, spread the word: tu.berlin/qw/studium-lehre/leh

my music listening experience is sorta ruined now after having to deal with audio de-syncs and clicks a lot in the last few days...

listening to random stuff like
"was that a click? maybe an xrun? does my code need more fixing?"
happens now everytime there is even a small click or noise 😭

now this gets a bit ridiculous, 8 frames for usb audio buffer size.

gets latency quite low, but easily xrun if playing anything complex in FLStudio.

seems stable/sustainable while there is very little stuff running though.
I like the small deviation in those "distance" numbers (it is how far userspace is from the kernel position in the ringbuffer).

Linux as a USB audio interface with minimal latency 😀

Hope users will appreciate the effort, the fact that this is running all inside a Linux embed device is quite something...
No external/dedicated USB Audio chips, it's all on the Linux side done in software.

I will take some big holidays after this 🌅 🏖️

Hundreds of thousands of Computers won't be able to upgrade to Windows 11, but that shouldn't make them eWaste.

Kudos to the @kde team for this amazing initiative!

Many people are thinking about ditching various US tech giants so I thought I'd try out how far I can go. I tried living about a month with as little Google, Microsoft, Apple & co as possible!

@amadeus You need to statically link plugins to not rely on any external resources. Sadly JUCE changed the default to dynamic link when Jules left...

As for flatpak. Nobody should distribute plugins in that format, it's not just technically wrong (sandboxing DSP) but also violates all plugin standards out there.

We finally got fixed system wide locations standardized (thanks VST3, CLAP, LV2), only for flatpak to come along and ruin it.

@falktx I added open source labels now but need to go through the list again to make sure I catched all of the OS developers. Thanks again for the suggestion! 🙌

Sonoj Convention 2025 – Oct 18–19, Cologne 🇩🇪 Independent event for those who create music and sound with computers—whether recording real instruments or working with digital tools. Visitor registration open, contributions for talks & concert / open mic welcome! 🎵 sonoj.org/convention #music #audio #opensource

The things we do for a few milliseconds of latency...

Like today, patching the Linux kernel to create a memory-mapped buffer that both the kernel and a JACK client can use at the same time.
(the previous/mainline code was using an alsa virtual device to expose the audio data)

Reduced latency of the "task" by around 20ms ✨

Now just need to deal with ARM memory barriers and other details to ensure a good sync, I think...

Not that anyone cares, but just built and installed Cardinal on the Darkglass Anagram unit for quick testing...

The JTB-Waves patch runs with a stable 58% DSP load.

Makes me think of fancy "build your own FX" possibilities...

This Anagram audio graph is looking complex now that USB audio is in the picture... 😁

Average 35% DSP load with this preset

PS. There will be macarons :)

Darkglass Electron announced Anagram, a multi-FX processor for the bass. It runs embedded Linux, uses open-source neural modeling tech, and relies on an LV2 plugins host and some FOSS plugins. @falktx is one of the fathers :)

Since I am the only one in the company that has dealt with opensource software licenses before, I am the one doing the page that lists the licenses used.
There's so much stuff hah 😱

How it looks so far: darkglass.com/pablito-licenses

Still WIP, but what do you think?
Specially interested on opinions from other opensource developers.
Thanks for the feedback in advance!
