Randomly Panning Audio

[indiedev123 <gz...@gm...>]

Hi,  I am trying to figure out how I could set audio such as background noise
like dog barking or birds to randomize the panning and volume.  I understand
how to play random sounds but understanding how to randomize their volume
and pan would be a great help!  

Thanks to all in advance!

Are you thinking of random but (for the duration of the sound) fixed  
volume and panning for each sound, or of randomly animating it while  
the sound is playing?

The former should be easy to achieve using the math.random() function (http://www.lua.org/manual/5.0/manual.html#5.5 
) and the sound:volume() and sound:location() methods (Pipmak manual  
section 3.9 "Sounds").

The latter would be more involved, probably involving some kind of  
spline functions, but still easily possible.

Does that answer the question or would you like more detail?

Hi,   Yes I am thinking of random but fixed for the duration of the sound.  
I will have a look at the math.random() function.  

Thank you so much!

You could use

			randomSound:location((math.random()*360), 0)
			randomSound:play()

keeping in mind the sound must be mono to play any positioning...

you could adjust the pitch property and volume similarly... makes for a
pretty good environment generator...
