awesome-musicdsp VS elk-pi

Check this out, there are several suggestions for Music DSP libraries: https://github.com/olilarkin/awesome-musicdsp

There is literally a section of this list titled "Hardware/Embedded" https://github.com/olilarkin/awesome-musicdsp#hardwareembedd...

Lastly, there's also often lists managed on github called things like "Awesome DSP". Here's one such list of links - https://github.com/olilarkin/awesome-musicdsp

Just found Elk Audio OS. Looks exciting, but I'm struggling to understand exactly what it is and how it might be useful. Anyone using it? https://elk.audio/

That might not matter too much for you - if not then you're set. But if it does, using small buffers is hard with Linux (and non-realtime OSes), since the kernel has other things to balance, so you can occasionally miss your deadlines and have audio glitches if the buffers are too small. These guys offer a linux distro that's been well tuned for audio processing, as well as an engine that makes it easy to drop in your effects algorithm without having to deal with hardware support and making that engine: https://elk.audio/

Overall there are JUCE embedded support.

If you need more bare bones there are some DSP only resources. Not sure if I saw there the RtAudio which is also very minimal -

I’ve run JUCE apps on embedded linux, a Raspberry Pi running maybe Elk Audio or Patchbox OS might be a good bet
