Algorithm for setting the correct "audio" volume based on distance (x, y)

Question

I am developing a game. How can I “fade out” the sound volume for sound based on the “distance” of the sprite from the current rendering scene? Suppose I have a world:

WIDTH_WORLD = 10000
HEIGHT_WORLD = 10000

Current Scene  
xCurrent = 800   ( + Width Res. = 800 + 1024 = 1824)  
yCurrent = 400   ( + Height Res. = 400 + 768 =... )

Far Sprite
xSprite = 7000 
ySprite = 3000 

What is a good algorithm for “calculating” sound volume (and possibly left / right channel ratios)? Thanks in advance!

Answer 1

General wave

• There are several approaches to attenuating volume. For instance. you can use the linear damping function, for example volume = max( 0, max_volume - max_volume/max_distance * distance ), or the function with reverse removal, for example volume = min( max_volume, max_volume / distance ).
