# Dataset Card for AudioSet

## Dataset Description
- **Homepage**: https://research.google.com/audioset/index.html
- **Paper**: https://storage.googleapis.com/gweb-research2023-media/pubtools/pdf/45857.pdf
- **Leaderboard**: https://paperswithcode.com/sota/audio-classification-on-audioset

### Dataset Summary
[AudioSet](https://research.google.com/audioset/dataset/index.html) 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](https://paperswithcode.com/sota/audio-classification-on-audioset)

### Languages
The class labels in the dataset are in English.


## Dataset Structure

### Data Instances
Example instance from the dataset:
```python
{
 '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|18685|17142|

#### `unbalanced` configuration
|           |train  |test |
|-----------|------:|----:|
|# instances|1738788|17142|

### Source Data

#### Initial Data Collection and Normalization
[More Information Needed](https://github.com/huggingface/datasets/blob/master/CONTRIBUTING.md#how-to-contribute-to-the-dataset-cards)

#### Who are the source language producers?
The labels are from the AudioSet ontology. Audio clips are from YouTube.

### Annotations

### Other Known Limitations
1. 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: 18685 audio clips out of 22160 originally.
   - Unbalanced train: 1738788 clips out of 2041789 originally.
   - Evaluation: 17142 audio clips out of 20371 originally.
2. 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.
