Hi Jan,
Seems reasonable; but I have little experience with using sndio
with Måns sox, much less the API. Perhaps Måns has an opinion,
too.
Fwiw, it would be helpful if example files could be
provided/generated showing where the improvement is.
Thanks. Sorry for the late response; I've been mostly
unplugged lately :)
