Is possible to acces the waveform of a song from a spotify app?

I am thinking on how to build an spotify app that does beat detection (extract bpm of a song). For that I need to access the raw audio, the waveform, and analyze it.

I am new to building spotify apps. I know that with "libspotify" you can access raw audio. Can you do the same through the spotify apps API? And how?

For the record, currently exist two spotify apps apis:

There’s a new endpoint I guess. See an example https://medium.com/swlh/creating-waveforms-out-of-spotify-tracks-b22030dd442b

That uses the endpoint: https://developer.spotify.com/documentation/web-api/reference/get-audio-analysis

Edit: I agree with commenter @wizbcn that this does not answer this question. Is it sort of incorrect to leave it here because I found this SO post while searching for info about visualizing the tack's waveform as in the linked article? Maybe I should make this a comment instead?

Unless you're really keen on writing that beat detection code yourself, you should look at the APIs provided by the EchoNest, which include that (and many other awesome things).

In a word: no. That isn't currently available in the Apps API.
