you suck at googling ```lua
-- 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
