Have you tried out the example script they gave in the documentation at the very bottom @rokoblox5 sent you? It should work.

Make sure your Sound object is playing.

That’s because the property is read-only, meaning that you can only read the value, and not edit it.

You could use the code that is provided, and make some simple edits, such as redefining the bar variable to your part/beam, and replacing the assigned Size variable with a Vector3 value.

You cannot, it just tells you how loud is the music right now, if you want to change the volume you would do Sound.Volume, which is a read & write property

Sound.PlaybackLoudness would return a number from 1 to 1000 to tell you how loud is your audio

To elaborate on what @rokoblox5 said, the property PlaybackLoudness is sort of like the Speed value of a car; It only shows a number when the car is moving. PlaybackLoudness, only shows a number when the audio is playing. The reason it’s read-only is that it’s designed so that you can make changes based on the current value of PlaybackLoudness.

Here’s a basic example of how you would do this.

-- LocalScript in PlayerGui
local part = workspace.Part -- path to part
local audio = part.Audio -- path to sound object
local sensitivity = 10 -- sensitivity to the loudness

local RS = game:GetService("RunService")

RS.RenderStepped:Connect(function() -- fires every frame
    local newSize = audio.PlaybackLoudness/(sensitivity*10)
   part.Size = Vector3.new(newSize,newSize,newSize)-- sizes the part according to loudness
end)

audio:Play() -- starts the audio, which then causes the PlaybackLoudness value to start changing

Greyed out means it’s a Read-Only variable. You can’t edit it, but you can still read it.
