Comment (by ccawley2011):

 > Another thing we have noticed while profiling: many (if not all) engines
 do its own sample / mixing before reaching the generic mixer. For instance
 Scumm::IMuseDigiInternalMixer, it would be nice if all those M-bit ->
 N-bit and/or mono/stereo conversions and mixing could be handled (and
 optimised / disabled) at one place.

 It should be possible to bypass the custom mixing in DiMUSE by selecting
 "Enable low latency audio mode" in the per-game options dialog. I'm only
 aware of a few other engines that do conversion independently of the
 mixer, namely SCI32 and the Broken Sword games.
