It visualizes something but I fail to detect the correlation with the music playing.

Syncing music from Spotify is illegal under their Developer Policy, a client wanted to do it recently and it seemed iffy that you wouldn't eventually get shut down.

I was tearing through GitHub last year to find a project like yours. Since then, this has been the gold standard for audio-reactive visuals in the browser. I was so impressed.

This is really cool. It would be nice to have a way use custom audio, but I really like the range of visualizations and the interface. (one very minor issue is that the scrollbars seem to intermittently appear on firefox when dragging sliders)

edit: It would also be cool to see the visualizer's current estimate for the BPM.

2nd edit: Is the shader code for the visualization's available anywhere?

Consider adding sample audio file to test features without login to Spotify - Helpful for people who are on mobile and keep passwords on desktop password managers

If your password manager doesn't have a mobile client, you should switch password managers.

It currently seems to use Spotify's audio analysis API [1], which might be hard to replace. [1] https://developer.spotify.com/documentation/web-api/referenc...

Indeed. I remember playing with Echo Nest back in the day and being blown away by it, Spotify seemed to either completely castrate it after buying them or just don't bother using it to its full potential.

Always interesting to see some of the rules imposed by a company that started by using unlicensed MP3s from The Pirate Bay. Guess you gotta keep the record companies happy.. after you make your first couple million, that is.
