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.

Why does it bother you? Why not focus on technical substance. It’s not a new idea but if you explore the project you will say many excellent features. The fact that there is a raspberry pi based dev board is simply to speed adoption and provide a reference implementation. It’s an excellent project.

Looks cool! …but what is it? Software, hardware or both? (And is the software part a Linux distro with a tweaked kernel?)

It's a pi header https://elk.audio/elk-pi-basic-dev-kit/ and an operating system that runs on pi

It runs on many arm flavors not just pi

Flexible enough to say the word "Citadel!" for example. :)

You can try it in your browser; Go to https://bbc.godbolt.org/?&disc1=sth%3ASuperior%2FSpeech.zip , then copy and paste this to the paste thing at the top right: SPEECH SAY Hello *SAY How are you?

Thanks for the link. :)

My comment was intended as an incredibly subtle reference to the trivia that the BBC Micro game "Citadel" 'famously' had speech generated by "Speech!" in its intro screen (but appreciate you taking the time to share the link :) ) as shown here : https://youtu.be/Hu5vu9SgGZI?t=44

For anyone else wanting to try out the emulator link in the comment above, HN messed up the formatting, so the asterisk prefixes were missed on the first two commands:

    *SPEECH

    *SAY Hello

    *SAY How are you?

'real time' generally means latency guarantees and trading some throughput for consistent low latency for interrupts and scheduling. So faster in some dimensions and slower in others. The Arch Linux wiki has some description of their real time patches: https://wiki.archlinux.org/title/Realtime_kernel_patchset

Arch wiki is an amazing source of practical information. It's like graybeard forums but distilled into a readable text. My last laptop ran Mint distro; whenever I searched around for HW issues it was always their wiki, fully stocked with useful info and steps how to fix stuff.

wow thanks for calling that out. Just spent an hour browsing through it and was basically an Operating Systems refresher course. Great resource!

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.

rule of thumb is that sound travels roughly 1ft per ms, so 5ms is the same as standing 5 extra feet from the speaker. Most musicians don't have much trouble up to around 10-20ms. Jitter is killer though - if the latency is randomly changing it's really annoying.

Yes it is true that you can deal with that amount of latency, but 10-20ms is way up in the 'very sloppy' range especially when it comes to recording.
