How would I make a sound reversed?

Roblox has removed -1 pitch due to moderation issues. People can easily bypass by making inappropriate sounds reversed and reverse it back to get an unmoderated inappropriate sound. So there's no way to make a perfect reversed sound, the only way is to make it cramped.

WAY 1:

local sound = script.Parent

sound:Play()

while wait(1) do
	for i = sound.TimeLength, 0, 0.1 do
		sound.TimePosition = i
	end
end

(This might not work, and it's very cramped, the quality might be bad)

WAY 2:

beg your friend to make a reversed sound lol

There is some websites that allows you to reverse the sound, it might get moderated, but it's an efficient way to make a reversed sound.
