Extraction

To use MID-FiLD, first clone this repository and run

unzip -q ./MiD-FiLD_dataset

to extract the MID-FiLD_dataset.zip file into MID-FiLD_dataset/ directory in the cloned repository.

After extraction, the overall tree will be like this:

.
└── MID-FiLD_code/

Metadata

1. Each sample in MID-FiLD consists of 5 fields of metadata specified in the paper:

• instrument
• track_role
• mood
• min_cc
• max_cc

2. The metadatas can be accessed through the MID-FiLD_metadata.csv file in the extracted folder. Ex):

import pandas as pd
df = pd.DataFrame(".MID-FiLD_dataset/MID-FiLD_metadata.csv", sep=",", index="False")

3. Each column of the dataframe contains the values for each metadata field, along with 2 more auxiliary columns:

• id: ID of the sample,

• split: tagged with 'train(3990 samples)' or 'test(432 samples)'.

  Samples for each split category are placed in the path ./MID-FiLD_dataset/train/* or ./MID-FiLD_dataset/test/*.

4. Below shows each unique class in columns 'instrument', 'track_role', and 'mood'.

Values in instrument: ['bamboo_flute', 'bassoon', 'brass_ensemble', 'clarinet', 'fiddle', 'flute', 'horn', 'oboe', 'sax', 'string_cello', 'string_double_bass', 'string_viola', 'string_violin', 'trombone', 'trumpet', 'tuba', 'whistle', 'woodwind_ensemble']

Values in track_role: ['accompaniment', 'bass', 'main_melody', 'pad', 'riff', 'sub_melody']

Values in mood: ['bouncy', 'calm', 'dreamy', 'funny', 'groovy', 'happy', 'hopeful', 'inspiring', 'magical', 'mysterious', 'peaceful', 'relaxing', 'romantic', 'sad', 'scary', 'sexy', 'tense', 'tragicomic', 'uplifting']

5. The ./assets directory contains the histogram of each classes in columns 'instrument', 'track_role', and 'mood'.
