That's necessarily going to be aspirational in at least some respects, though—it's limited by the hardware.

Although things may change a bit with the arrival of Apple M1 systems, the marketing mentions of VST in this context are fairly weasely. For users, good look finding more than a couple of plugin developers that make their plugins available for (a) a Linux based system AND (b) the ARM architecture. For developers, VST is just an SDK, and doesn't require OS support in any meaningful way. So sure, if you want to create…

Its a great project. It's intended to help hardware makers bring pro audio gear to market with less cost and less risk. Not as a retail vst host.

Yeah, it is a great project (though it's not a new idea in any sense). But the positioning of being "endorsed" by Steinberg bothers me, because it means nothing.

Elk seems to be pushing the RPi as the h/w platform. You will likely have a difficult time finding an RPi with an ethernet chipset capable of correctly doing PTP.

I don't think you need the sub-microsecond resolution PTP compatible PHYs offer. I was hoping to get away with software timestamping which I believe should still give you sub ms synchronization. My real question, I guess, is how in sync do the speakers need to be? Just on the order of human perception, or do we need them to be in phase?

I have some aging Slim Devices units in my house system that I've been contemplating replacing with a custom system. However, I would just use wifi to an RPi with a suitable DAC installed. There'd be no per-speaker sync, since the DAC->speaker connection is analog, and before the DAC there'd be essentially streaming code that would always be handling both channels.

I’ve never understood the latency requirement for professional gear, are you able to articulate why there’s a need for lower latency than average consumer gear?

Different use case - consumer gear is generally only used for listening to recordings, whereas professional gear is often used for real time recording of someone who's playing an instrument while listening to the output.

When I saw the headline, I wondered/hoped if it was an OS with an audio/only UI. I'm sure this is cool, but a fully thought-out audio-only UI would be fascinating.

I remember ADRIANE being included in the Knoppix ISOs back in the day. You might find it interesting: http://www.knopper.net/knoppix-adriane/index-en.html

It’s a Linux distribution with real-time kernel. Here’s a download link if anybody is interested: https://github.com/elk-audio/elk-pi/releases

When I read things like this, I really wish BeOS, with its already pervasively multithreaded kernel, had won the audio OS wars. _Le sigh._

It only takes a small amount of latency (5 ms or so) to noticeably impact performances by musicians. Latency is also an issue when you want to monitor a live signal along with other recorded audio, like in a DAW. It is not as big a deal with a playback only device.

I started developing a blind computing system in the late 80s based on a BBC Micro and a very early speech synthesizer. It never went anywhere, and I'm no longer in contact with the blind friend who was helping me, but I often wonder if today's solutions such as Apple's Voiceover aren't the ideal solution. They seem to be trying to adapt the GUI for the blind, rather than trying to build a text/voice based system fro…

As a legally blind developer who has worked on accessibility for a while (see my HN profile for more), I'm inclined to agree with you. We use screen readers like VoiceOver because, practically, we often need to access mainstream applications. But I think we tend to get too dogmatic about going mainstream, to the point that some of us are disdainful toward systems designed specifically for blind people, particularly i…

Yes it was a software synthesizer called "Speech!" by Superior Software, blown into a ROM.

As you might have guessed, many audio-only UIs have been developed for blind people over the decades. One example of an audio-only PDA (from the time when the term "PDA" was still widely used) was the LevelStar Icon. (Disclosure: I did some contract work for LevelStar in 2005-2006 and was friends with the lead developer.) After some digging I found an old audio presentation about the LevelStar Icon here:
