Adds reverb functionality to sound system
TODO: Make a proper sfxMixer api that will route voices to channels that have the effects slots added to them. this is just a place holder for a more complete implementation
DSound has since been deprecated and xaudio2 would require us to write our own 3d spatialization and mixer
Load devices the same way we load in the gfx end
setup sfx provider
run sfx devices on startup
various fixes around sfx null device
added the bitrate and samplerate globals
added the hrtf global code is in to use this but not setup yet
Adds speed of sound to the sound system
SFXAmbience now has a property for speed of sound for different mediums, can also be set directly
Ground work, this commit enables reverb zones and opens the slots for
other effects to be added later. Tested using the full template. Build
your openal dll and your full.exe use one of the environment presets and
it will work
while not a major issue per-se, the sheer number of times the engine has to jump back in memory and backfill data in a given class can add up. First run of... many.,
