My toilet sounds like an angry goose

My toilet is making strange sounds when it's flushed. I suspect something in the fill valve is vibrating. Here is a video of it. It's pretty intermittent and sometimes it's longer and louder than that.

Do I just need to replace the fill valve?

Update

It's definitely something in/on/around the fill valve. While inspecting the flapper today I drained the toilet and upon refilling it I discovered that I can reliably recreate the sound by filling the tank up when empty. Here is a video of it.

I tried it several times and the sound is definitely coming from the left where the fill valve is.
