live audio processing?

I’d like to see live audio processing in halo 4 or if too late in halo 5.

halo has all ways had great sounding music but for some reason during mastering and the mix down, some one forgets something. Example not using the Pultronic tube effect that was missing form the CEA music or the guitar that was in the wrong key in “Halo: CE - Rock Anthem For Saving the World.” or not adding a small amount of reverb that makes the drums in the halo theme sound tremendous.

so what is live audio processing?

live audio processing is when the original sound is played with sound effects layered on top, being processed while the game is playing.

i.e.
normal sound playing:
the original sound has reverb.
and base lift.
as a result the drums are over powering.

live audio processing:
during the game the sound is played simultaneously, three times overlapping each other
one.
track one handles base + reverb and is paned over slightly to the left

track two handles vocals and high frequencies paned slightly to the right

track three handles the mid range of sound and pan is set to the middle.
This results in high quality audio with depth but does require more processing power as three sounds are played and being processed instead of just a sound being played.

Real life examples:
live audio processing: - YouTube
normal audio: http://www.youtube.com/watch?v=i35CUy2tAQU
or
live audio processing: - YouTube
normal audio: - YouTube

but if the extra strain on cpu by live audio processing takes away for the rest of the game I would rather have normal music

thoughts?
