function onSoundPlayRender ( )
    if ( soundHandler ) then
        local leftData, rightData = getSoundLevelData ( soundHandler )
	if ( leftData ) then
            dxDrawRectangle ( 0, 0, 64, leftData / 32767 * 256, tocolor ( 255, 0, 0 ) )
            dxDrawRectangle ( 64, 0, 64, rightData / 32767 * 256, tocolor ( 0, 0, 255 ) )
        end
    end
end
addEventHandler ( "onClientRender", getRootElement(), onSoundPlayRender )
