This function gets the left/right level from a sound element. If the element is a player, this function will use the players voice.

Syntax

int, int getSoundLevelData ( element theSound )

OOP Syntax Help! I don't understand this!

Method: sound:getLevelData(...)


Required Arguments

  • theSound: the sound element which level data you want to return.

Returns

Returns a 2 values with Left, Right level data from sound (range is [0,32768]), false otherwise.

Example

This code creates vertical lines of right and left level in center of screen from top to bottom. [1] Key 9 - start, key 0 - stop. 

local handl = nil
local sx,_ = guiGetScreenSize()
local colors = { tocolor(255,0,0),tocolor(0,255,0) }
 
function clientRenderFunc()
    if(handl) then
	local ls,rs = getSoundLevelData(handl)
	if(ls ~= false) then
            dxDrawRectangle(sx/2-10,0,10,128*(ls/32768),colors[1])
            dxDrawRectangle(sx/2+10,0,10,128*(rs/32768),colors[2])
	end
    end
end

function clientSoundStopFunc(_)
    if(source == handl) then
	removeEventHandler("onClientRender",root,clientRenderFunc)
	removeEventHandler("onClientSoundStopped",root,clientSoundStopFunc)
	handl = nil
    end
end
 
function musicStartFunc()
    if(not handl) then
        handl = playSound('nya.mp3')
        addEventHandler("onClientRender",root,clientRenderFunc)
	addEventHandler("onClientSoundStopped",root,clientSoundStopFunc)
    end
end
 
function musicStopFunc()
    if(handl) then
        stopSound(handl)
        handl = nil
        removeEventHandler("onClientRender",root,clientRenderFunc)
	removeEventHandler("onClientSoundStopped",root,clientSoundStopFunc)
    end
end
 
bindKey("9","down",musicStartFunc)
bindKey("0","down",musicStopFunc)
