SetSoundListenerPosition

From OxeyeWiki

audio.setSoundListenerPosition(x, y, z [, speedX, speedY, speedZ])
Sets the position from which oriented and tracked sounds' volume and panning is calculated. The relative speed of the listener and the sounds generates a doppler effect.
Parameter	Expected Type	Description
x	A number	Position in space, in meters.
y	A number	Position in space, in meters.
z	A number	Position in space, in meters.
speedX	A number	The speed of the sound in space, for creation of doppler effects, in meters/second.
speedY	A number	The speed of the sound in space, for creation of doppler effects, in meters/second.
speedZ	A number	The speed of the sound in space, for creation of doppler effects, in meters/second.
Returns
Returns nothing.

Example

   -- listen from the center of the world
   audio.setSoundListenerPosition(0,0,0)

   -- first set orientation: [[setSoundListenerOrientation]]
   audio.setSoundListenerOrientation(0,0,1,0,-1,0)
   -- now listening abit from above.
   audio.setSoundListenerPosition(0,-10,0)

   -- listening abit from left
   audio.setSoundListenerPosition(-10,0,0)

   local you = {x = 100, y = 100}
   local res = 1/32 -- 32 pixels is 1 meter.
   -- z set a bit negative to get less sudden panning.
   audio.setSoundListenerPosition(you.x*res,you.y*res,-300*res)
   
   -- moving too!
   you.speedX = 10
   audio.setSoundListenerPosition(you.x*res,you.y*res,-300*res, you.speedX*res, 0, 0)
