How would you change a players FOV (field of view) based on the music playing?

1. so i was wondering how you would change a players FOV based on the music playing, so basically imagine that your in a game and music is playing, based on the beat / base of that music, the players FOV would increase or decrease. when the song would stop, it would return to normal. If you could answer this with a script or a link to somewhere explaining how to do this, it would be really helpful, Thanks!

EDIT: I'm wondering this because i know a game that does what i just described, it changes the FOV based on the music.

This is possible, as the developers of Jailbreak have already done so. PlaybackLoudness returns a value between 0 and 1000, showing how loud the sound is.

Try this:

local cam = workspace.CurrentCamera
local RS = game:GetService('RunService')
local sound = workspace.Sound -- Let's say there's a sound in workspace that's playing

RS.RenderStepped:Connect(function()
        if sound.IsPlaying the --check to see if the sound is playing.
               cam.FieldOfView = 70+((sound.PlaybackLoudness/1000)*5)
        end
end)

Not has been tested, but it should work
