Quote: 2. Does the software automatically include any filtering for distance changes or a doppler effect for speed? (i.e. a simple room model?) Or does it only change the volume of the sound as you get closer / further away?
According the A6 Features list the engine does include doppler.
Quote: 10. I understand that sounds can be attached to objects. But did we work out that sounds can also be attached to zones on the level?
Have you tried adding a sound using the wed? (Object - Add Sound) Or, if not you wed you could probably write a short piece of c-script code that could turn a sound on when the player/camera got close enough to a certain point.
Hope that helps. Sorry I cant answer any of the others.
