That sounds like the better choice, yes. I'm sure there are some reasons why
OpenAL uses m/s, but unless we know why and it's a strong enough reason, I
don't think that it's enough for us to just duplicate that part.

PS. One guess as to why OpenAL want to use m/s it so that the default speed of
sound = 343.3 makes sense. On the other hand, this is kind of similar to the
gravity property in the Bullet physics library, which defaults to a unit-less
10 (all things are unit-less in Bullet).
