The help page says that questions need to be about sound design, but don't give any further clarification. So what constitutes sound design in the context of being on topic for this site?
The typical SE "what kinds of questions can I ask here" page goes something like:
This SE-Site is for people who do/are/interested-in XXX... We welcome questions like/about/of-the-kind - Question topic 1 - Question topic 2 - etc. Additional text that further explains the nature of the community (e.g. academic vs. enthusiast) and the types/varieties of questions that are or are not on topic.
I have found that the current "what questions are on topic" help page does not have this kind of additional explanitory information common to other SE sites.
I would find it helpful for the community to further expand on the definition of "sound design" as pertains to setting the boundaries of what is on/off topic for this site.
Ultimately, the discussion engendered here might be used to expand the site's description on the help page.
