Downloading file and decoding from base64

I'm trying to create a script that downloads and converts audio from Google Cloud.

The audio is returned as a json file with wav audio within encoded in base64.

How would I make a script that downloads and decodes only this one specific file?

You can download an example json file from here:

There is a lot of info on this: try googling javascript decode base64 into file.
