'''3-dimensional sound''' (3D sound) is a type of manipulation of audio output to give the illusion that sound is coming from different directions. It has become possible in [[Scratch 3.0]] due to new [[Sound Blocks|Sound blocks]], mainly [[Set () Effect to () (Sound block)|<sb>set [ v] effect to ()::sound</sb>]] and [[Change () Effect by () (Sound block)|<sb>change [ v] effect by ()::sound</sb>]].

This technique is only effective on devices using stereo speakers, headphones, or earphones. It will not have the desired effect on monophone speakers.

== Scripts ==
To make 3-dimensional sound, create the following scripts in the sprite that will play the sound, with "listener" representing the sprite in the position that the person hearing the sound would be in:
<scratchblocks>
when gf clicked
repeat until <(playing sound) = [0]>
play sound (sound v) until done
end
stop all sounds
when gf clicked
repeat until <(playing sound) = [0]>
set volume to ((200) - (distance to (listener v)))
set [pan left/right v] effect to ((x position) - ([x position v] of (listener v)))
end
</scratchblocks>

If the sound has to repeat infinitely instead of the script repeating until something happens, the [[Repeat Until () (block)|repeat until]] blocks should be changed to [[Forever (block)|forever]] blocks:
<scratchblocks>
when gf clicked
forever
play sound (sound v) until done
end

when gf clicked
forever
set volume to ((200) - (distance to (listener v)))
set [pan left/right v] effect to ((x position) - ([x position v] of (listener v)))
end
</scratchblocks>
