well I guess I forgot to request my feature
I think you should be able to get peak level for each channel playing
it could be very useful, and not just in music games
characters could lip sync to the loudness of their voice
you could have an accurate measurement of how loud something is
if you wanted a model for when a npc should hear something
of course with music games it opens up alot more interesting and intricate possibilities
is the separate channel thing something difficult to implement?
