In one Greasemonkey script that I wrote, I use a little audio sound. I don't remember where I had found that specific string of text that generated the sound I use. Seems like there was an online sound maker that gave me the Base64 text string afterward. So now I'm looking for something like that again.
Here's one that I just found that seems similar the the one I remember from years ago, but not quite the same:
