The dataset could not be loaded because the splits use different data file formats, which is not supported. Read more about the splits configuration. Click for more details.

Couldn't infer the same data file format for all splits. Got {'train': (None, {}), 'test': ('parquet', {})}

Error code:   FileFormatMismatchBetweenSplitsError

Dataset Card for AudioSet

Dataset Summary

AudioSet is a dataset of 10-second clips from YouTube, annotated into one or more sound categories, following the AudioSet ontology.

Supported Tasks and Leaderboards

audio-classification: Classify audio clips into categories. The leaderboard is available here

Languages

The class labels in the dataset are in English.

Dataset Structure

Data Instances

Example instance from the dataset:

{
 'video_id': '--PJHxphWEs',
 'audio': {
  'path': 'audio/bal_train/--PJHxphWEs.flac',
  'array': array([-0.04364824, -0.05268681, -0.0568949 , ...,  0.11446512,
          0.14912748,  0.13409865]),
  'sampling_rate': 48000
 },
 'labels': ['/m/09x0r', '/t/dd00088'],
 'human_labels': ['Speech', 'Gush']
}

Data Fields

Instances have the following fields:

video_id: a string feature containing the original YouTube ID.
audio: an Audio feature containing the audio data and sample rate.
labels: a sequence of string features containing the labels associated with the audio clip.
human_labels: a sequence of string features containing the human-readable forms of the same labels as in labels.

Data Splits

The distribuion of audio clips is as follows:

`balanced` configuration

	train	test
# instances	18683	17141

`unbalanced` configuration

	train	test
# instances	1738657	17141

Other Known Limitations

The YouTube videos in this copy of AudioSet were downloaded in March 2023, so not all of the original audios are available. The number of clips able to be downloaded is as follows:
- Balanced train: 18683 audio clips out of 22160 originally.
- Unbalanced train: 1738788 clips out of 2041789 originally.
- Evaluation: 17141 audio clips out of 20371 originally.
Most audio is sampled at 48 kHz 24 bit, but about 10% is sampled at 44.1 kHz 24 bit. Audio files are stored in the FLAC format.
