Spotify Audio Analysis Client

Illustrates how to use Spotify's audio analysis web API to fetch the audio analysis for a Spotify track.

Setup

  1. Run npm install to install the tool's dependencies.
  2. Create the configuration file for authenticating with Spotify:
    1. Get a "client ID" and a "client secret" by following Spotify's "Create an app" instructions.
    2. Create a file called ./creds/spotify.js and populate it with your "client ID" and "client secret". The file should be formatted like this: 
      export const clientId = 'YOUR_ID_HERE';
export const clientSecret = 'YOUR_SECRET_HERE';

Usage

node main.js <spotify-track-id> <spotify-analysis-output.json>

For example, the Spotify track ID for Gangnam Style is 03UrZgTINDqvnUMbbIMhql so you can fetch Spotify's audio analysis for it and store it in gangnamStyleAnalysis.json with this command:

node main.js 03UrZgTINDqvnUMbbIMhql gangnamStyleAnalysis.json

Looking up a Spotify track ID

  1. Find the song of interest in the Spotify web app.
  2. Click the "..." to the right of the song title. ((1) in the screenshot)
  3. In the context menu that appears:
    1. Choose "Share"
    2. Choose "Copy Song Link" ((2) in the screenshot)
  4. The track's URL should now be on your clipboard. For example, for Gangnam Style my clipboard contained https://open.spotify.com/track/03UrZgTINDqvnUMbbIMhql?si=e148916771984610
  5. The last path component of the URL is the track's ID. For example, for Gangnam Style it is 03UrZgTINDqvnUMbbIMhql.
