Data Files

• artists.json

A list of each artist in the dataset. Rather than extracted from tags in the mp3 file, they are hand-entered via categorize.py to ensure correct normalization.

• compressed

Loosely organized directory of mp3/m4a/etc. files for the base data set.

• genres.json

List of each possible genre in the dataset. Handwritten and used by categorize.py for manual genre entry.

• meta.json

The main catalogue of metadata associated with each WAV file. Currently includes genre and artist(s) info, in addition to file paths of compressed/WAV versions of the audio data.

• wav

Directory of uncompressed audio data files. Automatically populated by decompress.py
