AUEffectBase's Initialize method will take care of this for you, so you
shouldn't need to do anything about this. You can always overide
ChangeStreamFormat to check that the new format can at least do the number
of channels you support (but this is generally best left until initialize,
as for some configs you can't actually tell until both sides have been set
if the settings are appropriate - that's why we generally prefer to leave
this until initialize) - but yes, in this case its very straightforward.
