+This dataset is preprocessed and compressed to 32khz mp3 files. The bytes of the mp3 files are embedded.
+The mp3 bytes can be decoded quickly using for [example](https://github.com/kkoutini/PaSST/blob/4519e4605989b8c2e62dccb5b928af9bf7bf8602/audioset/dataset.py#L55) or  [minimp3](https://github.com/f0k/minimp3py).

+Take a look at the original dataset for more information.
+The original dataset contains the following:
+
+10 second snippets of audio, in a directory format like 'audio/{0:3}/{0}.ogg'.format(sample_key)
+VGGish features as JSON objects, in a directory format like 'vggish/{0:3}/{0}.json'.format(sample_key)
+MD5 checksums for each OGG and JSON file
+Anonymized individual responses, in 'openmic-2018-individual-responses.csv'
+Aggregated labels, in 'openmic-2018-aggregated-labels.csv'
+Track metadata, with licenses for each audio recording, in 'openmic-2018-metadata.csv'
+A Python-friendly NPZ file of features and labels, 'openmic-2018.npz'
+Sample partitions for train and test, in 'partitions/*.txt'
