Descr sounds enviro.txt

This file is delegated file from descr_sounds.txt for manage sound bank "water" "weather" "fauna" "terrain_ambient".

Note: Sound bank "fauna" is only using in RTW.

BANK "water"

This part start with

 DEFAULT: modifiers
 
 BANK: water

DEFAULT = setting which declare by this would be using for follow sound events unless specified in event or DEFAULT is declared in the same category again.

List of modifers (X indicated value for setting)

3d - sound has distance/direction modification

1d - sound has no distance/direction modification

Streamed - read from disk instead of embedded file in memory at the game startup

looped - overwrite the parameter in play_tracked_sound

ducking - temporary lowering other sounds (not use in vanilla RTW but could be used in RTW)

retrigger X - delay before retriggering the sound, using for music (X is in second)

minDist X - minimum distance which would hear the sound (X must more than 1.0)

maxDist X - maximum distance which sound would still be heard

priority X - (X = between 0 to 9999)

Volume X - modifier to based sound volume set in the preference (X = between -100 to 0 db)

probability X -

minPitch X -

maxPitch X -

dry_level X - (X = 0 to 1 }

wet_level X - (X = 0 to 1 }

delay X - delay in seconds before next 3d sounds start playing

randomdelay X - delay within seconds before next 3d sounds start playing

probradius X -

fadein X -

fadeout X -

pref X - sound preference setting to be use for events below (X = sfx/speech/music/INTERFACE }

pan X - 2D events only, from 0 (hard-left) to 1.0 (hard-right) 0.5 - default

ignore_pause X -

distancepriority X -

effect_level X -

rndvolume X -

Setting of sound event of this sound bank is very specific to each category.

Note "spring" and "autumn" also using along summer in vanilla RTW but real game effect still not clear.

BANK "weather"

This part starts with

 DEFAULT: modifiers
 
 BANK: weather

DEFAULT = setting which is declared here will be used for the following sound events unless specified in event or if DEFAULT is declared in the same category again. Modifier usage is the same as above.

Rain

 precipitate { none, rain, snow, hail ; the same as in descr_daytypes.txt in RTW or weather_db.xml in M2TW }

lod X level of detail here with X set from 100 to 1000 to 10000 but with no explanation on how and why it is using.

"thunder_delay_min" and "thunder_delay_max" are not using in vanilla M2TW.

Note "climates" is not valid condition to use with thunder section.

BANK "fauna" (RTW ONLY)

This part only using in RTW and start with

 DEFAULT: modifiers
 
 BANK: fauna

DEFAULT = setting which declare by this would be using for follow sound events unless specified in event or DEFAULT is declared in the same category again. Modifier usage is the same as above.

 type vulture
   action idle
       event probability .02

           {sample name} ...
       end

Seem to be setting for random bird cry. This part has limit setting and not clear if there are other types and actions to use or not. Most of animal sounds seem to mostly move to bank: terrain_ambient.

BANK "terrain_ambient"

This part start with

 DEFAULT: modifiers
 
 BANK: terrain_ambient

DEFAULT = setting which declare by this would be using for follow sound events unless specified in event or DEFAULT is declared in the same category again. Modifier usage is the same as above.

This is specfic setting for terrain_ambient sound bank

 	channels	10		; number of sounds to be played simultaneously
 	delay		15		; delay between updates (in seconds)
 	radius		100  	; radius around the camera where the sounds are played (in metres)
 	radius_min  40

Terrain ambient sound event are structuring their entries like this.

 season { season_type ; the same as in descr_daytypes.txt in RTW or weather_db.xml in M2TW }
   daytime { daytime_type ; the same as in descr_daytypes.txt in RTW or weather_db.xml in M2TW }
     weatherevent { weatherevent_type ; the same as in descr_daytypes.txt in RTW or weather_db.xml in M2TW }
       terrain { terrain_type }
       event probability X modifiers
         folder { base path }
           {sample name}     modifiers (any of probability, volume etc)
           {sample name} ...
         folder { base path , in case files have different location}
           {sample name}     modifiers (any of probability, volume etc)
           {sample name} ...
       end

Available "season_type" are the same as other parts above.

Available "daytime_type" are... (setting is in descr_skydome.txt but hardcoded name could be found in weather_db.xml )

 sunrise
 mid_morning
 morning
 midday
 sunset
 mid_evening
 night
 midnight

"weatherevent_type" is type of weatherevent which defined inside descr_daytypes.txt in RTW or weather_db.xml in M2TW.

"terrain_type" is type of terrain as defined by descr_battle_map_movement_modifiers.txt on battle map.

 rock
 sand
 mud
 swamp
 grass_dry
 grass_short
 grass_long
 scrub_dense
 forest_sparse
 forest_dense
 water
 ice
 snow {not use here, it define by season and climate instead)
 mud_road
 stone_road
 wood (not in descr_battle_map_movement_modifiers.txt but still count as valid type)

Note: Vanilla setting of terrain_ambient are attached probability to all of event to make them trigger at random based on probability given to each events.
