I got dynamic audio to work using the audio_play_sound_at (emitters caused some issues but this seems to do the same thing w/o emitters). I some some questions: What is the most common model? I'm currently using audio_falloff_exponent_distance falloff factor of 2. Generally, when is exponential vs linear used? How do I mix ambiance of different types since I can only use of model? For example, a huge waterfall needs to always have its sound heard even when far away which fits the exponential model. However, a small torch needs to go silent when far away because its not as loud so the exponential model doesn't work. Should I be using a linear model and tweak the falloff variables to create the correct sound? Like the waterfall would have bigger distance numbers?
