是否可以从 Spotify 应用程序访问歌曲的波形？

Question

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:

• Current
• Preview

Answer 1

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).

see Getting the tempo, key signature, and other audio attributes of a song

Answer 2

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

Answer 3

There's a new endpoint I guess. See an example https://medium.com/swlh/creating-waveforms-out-of-spotify-tracks-b22030dd442b?source=linkShare-962ec94337a0-1616364513

That uses the endpoint https://developer.spotify.com/documentation/web-api/reference/tracks/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?
