Replicating Fade effect?

I’m attempting to achieve a Fade / Phase effect similar to the one shown below.
I know I can replicate this using Tweens etc; however, it’s the configuration I’m struggling with.
I.E. How to set up the pulse effect (Where it fades out and back in) , Time taken to fade & amount of pulsing - I’m wanting it to match or fade in sync to the sound if at all possible.

Thank you!

In order to achieve this with sound you can use PlaybackLoudness here Sound | Roblox Creator Documentation it return a range of 0-1000 then you can convert it to a range of 0-1 just like a transparency range by using this formula : mathematics - How to convert a number from one min\max set to another min\max set? - Game Development Stack Exchange
