GetSoundWaveData

This function gets the wave form data for an audio stream which is a table of floats representing the current audio frame as a wave. This allows things like visualisations.

If the element is a player, this function will use the players voice.

Syntax

table getSoundWaveData ( element sound, int iSamples )

OOP Syntax Help! I don't understand this!

Method: sound:getWaveData(...)

Required Arguments

• sound: a sound element that is created using playSound or playSound3D. Streams are also supported
• iSamples: allowed samples are 256, 512, 1024, 2048, 4096, 8192 and 16384.

Returns

Returns a table of iSamples floats representing the current audio frame waveform. Returns false if the sound is not playing yet or hasn't buffered in the case of streams.

function onSoundPlayRender ( )
    if ( soundHandler ) then
        local waveData = getSoundWaveData ( soundHandler, 256 )
	if ( waveData ) then
            for i=0,255 do
                dxDrawRectangle ( i, 128, 1, waveData[i] * 128)
            end
        end
    end
end
addEventHandler ( "onClientRender", getRootElement(), onSoundPlayRender )
