Contribute — propose a file extension

Tell us where to find evidence about Csound (mapped to pl/csound). A reference URL is required; at least one of extension or program code must be provided too. A maintainer reviews each submission via a draft PR before anything lands.
Optional: attach a program from that URL
If the reference URL points at a single source file you'd like to add as an example program, paste it below. The workflow will write it under languages/Csound/programs/<sha>/. Keep under ~200 lines.
(or open the pre-filled issue directly)
