v2.3.1-1.20.1

Effective 2.3.1 - 1.20.1:

• Reworked all audio ambience to make it more dynamic. Different ambient effects will now stack on top of each other
  depending on the environment's properties.
  • Added bees in floral biomes during the day
  • Added birds in forests during the day
  • Added cicadas in savannas during day
  • Added crickets in temperate (excluding swamps to use their dedicated cricket and frog ambience instead) and floral
    biomes at night
  • Added frogs and crickets in swamps at night
  • Added day jungle animals in jungles during the day
  • Added night jungle animals in jungles at night
  • Added owls in forests at night
  • Added rustling foliage in forests, floral biomes, swamps, jungles, wooded badlands and lush caves
  • Added water dripping in dripstone caves
  • Added water streams in lush caves
  • Added water flowing in rivers
  • Added water waves in beaches and oceans
  • Added arid wind in deserts and mesas
  • Added cave wind in caves (excluding the deep dark to use its dedicated ambience instead)
  • Added cold wind in cold biomes (excluding peaks to use their dedicated wind instead) and mountain slopes
  • Added deep dark ambience (classified as wind)
  • Added end ambience (classified as wind)
  • Added mountain wind in peaks
  • Added soft wind in temperate, floral, savanna, jungle and mushroom field biomes
• Split ambient effects into 4 categories (animals, foliage, water and wind) and added volume configuration for each
  • Allows the user to fine tune their audio ambience exactly how they want. If you don't like animal sounds in
    ambience mods for instance, you can completely disable them and keep the rest!
• Changed cascade audio detection to make it so cascades underground can only be heard by players underground, and
  surface cascades can only be heard by players on the surface, to reduce the amount of cascade audio coming from
  underground sources.
