Airbending pretty cool, but Idont think that it can have a sub-skill. oxygen is more a atomic ability then a air ability and same goes for nitrgen.

as for soundbending thats not possible either if your a airbender your just filling your gut with air and yelling at the top of your longs. sure aang used it to call appa, but thats becaue of the bison he had.
