What is the best audio analyzer API?

Hey everyone! Does anyone know if there is an API which can analyze audio waveforms and return data which could then be used to create templates to create visualizers for music like this? I know I would have to come up with a way to turn the raw data into time and position variables and then dynamically render the Jason for the render, but I was just wondering if anyone knows of a API as a service one could use to get the data, rather than building a custom analyzer app.

By the way, check out the demo of the new react native for web app I am working on for wikacy. I am going to try to develop some more on shotstock for this one, such as a template creator and what not and try to get my renders up.

It will be on apple and Android too. And I am really excited because I have learned so much after building the first one I feel like I can accomplish what I meant to do at the beginning now.
