@lupyuen I tried to use noflow, but gave up after a while. And started over with something I call "Pink2Web", which is a small (few MB) and fast (near C/C++) runtime, with a graphical UI. See https://github.com/niclash/pink2web
The same UI is demo'd here; https://www.linkedin.com/posts/niclashedhman_this-is-the-beginning-of-a-programming-tool-ugcPost-6608636732810371072-d6sh although trying to apply that to audio stream processing.
@niclas Yep that would be helpful thanks! 🙂
@lupyuen You will probably need help, since it is not finished, using an obscure programming language (Pony) and compiles to native, and I am targeting Raspberry Pi. Let me see if I can set up a sandbox on a public IP.
