How do you change the BickColor of a part depending on a sounds PlaybackLoudness?

This is a ServerScript because on a LocalScript it didn't work either.

local sound = workspace.MusicHandler.Music

sound.Changed:Connect(function()
    if sound.PlaybackLoudness >= 300 then
        script.Parent.BrickColor = BrickColor.Random()
    end
end)

PlaybackLoudness is readonly. Changed will not fire unless a property is written to (correct me if I'm wrong). PlaybackLoudness only updates itself. Also note that Changed also does not fire in physics-related changes. You will need to look for changes constantly. I suggest using the Heartbeat event of RunService because PlaybackLoudness runs with the server. A while-true statement would also be fine.

local RunService = game:GetService("RunService")

local sound = workspace.MusicHandler.Music

RunService.Heartbeat:Connect(function()
    if sound.PlaybackLoudness >= 300 then
        script.Parent.BrickColor = BrickColor.Random()
    end
end)

PlaybackLoudness will normally never be above 300 (unless the Volume is super loud.)

Try numbers like 10 and 20 to check the loudness.

Also, sound.Changed may not occur when the PlaybackLoudness changes due to how often it can fluctuate. You may need to use a while loop to check it.

Example:

local sound = workspace.Sound

sound:Play()

while true do
    print(sound.PlaybackLoudness)
    wait(0.5)
end

yes, but i'm saying to not check against a number like 300. try using 10 instead of 300 with some loud audio megukoo 877 — 4y

again, try going lower until you find a match. PlaybackLoudness is dependent on the audio. try starting from 1 until you find a suitable number. megukoo 877 — 4y

actually, PlaybackLoudness may not fire the Changed event. try using a while true do loop to check it megukoo 877 — 4y

i've just tested it in Studio myself, PlaybackLoudness does not influence the Changed event in a Sound. you need to use a loop megukoo 877 — 4y
