In /usr/ccrma/media/databases/hiphop-gene/ are the following files:
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
Utility Tools
- decompress.py
Convert files in compressed/ to WAV format, and place them in wav/.
- build_artists.py
Add any new artists in meta.json to artists.json (normally not necessary as categorize.py should do this automatically).
- categorize.py
Search for new files in compressed/<tt> and request genre and artist information. Stores this all in <tt>meta.json.
- export_mat.py
Export meta.json data into a format convenient for use in Matlab.
