Cats, The Musical! Algorithmic Song Meow-ification

How are you supposed to sing along with your favorite TV theme song every week if it doesn't have lyrics? At my house, we "meow" along (loudly). We also code, so I built 'Meowifier' to convert any song into a cat's meows. Join me in this exploration of melody analysis APIs and gratuitous cat gifs.
I built an application that takes a song's audio and outputs a new audio file with that song's melody **sung by cats**. It's a technical feat. It's hilarious. It's beautiful. It's a new way to waste time on the internet.
