Nice one.

* Space in the $OpenBSD$ marker (portcheck -N complains)
* COMMENT should start lowercase

If you write in pkg/DESCR that a command line tools is available, you
should probably install it. I assume examples/rnnoise_demo.c is meant.

Version attached with the above fixed and pkg slightly adjusted to make
clear that the command line tool is provided as code.

The URL https://arxiv.org/pdf/1709.08243.pdf can be downloaded with
ftp, but the wget user agent seem to be forbidden. This might confuse
users... is this worth mentioning?
