SpotifyPro-Integration: Add AudioAnalysis

[YeonV]

hello hackers!

In our current WIP-SpotifyPro-Integration, we would like to provide users the ability to visualize the relative dominance of pitches throughout any track on Spotify using the Spotify API to visualize an audio analysis for virtually any song.

Pitch content is given by a “chroma” vector, corresponding to the 12 pitch classes C, C#, D to B, with values ranging from 0 to 1 that describe the relative dominance of every pitch in the chromatic scale. For example a C Major chord would likely be represented by large values of C, E and G (i.e. classes 0, 4, and 7).
Pitches are organized into 12 classes -- C, C#, D, D#, E, F and so on. This is known as the chromatic scale. Use a range of colours to differentiate these pitches.
Zoom out to recognize chorus structures
Zoom in to find specific chords
Hover feature, that can see percentage of chord value at a particular time.
