# Dataset Card for AudioSet

## Dataset Details
This repository contains the balanced training set and evaluation set of
the [AudioSet data](
https://research.google.com/audioset/dataset/index.html). The YouTube
videos were downloaded in March 2023, so not all of the original audios
are available.

The distribuion of audio clips is as follows. In parentheses is the dict
key used for HugginFace `datasets`:
- `bal_train` (`train`): 18685 audio clips out of 22160 originally.
- `eval` (`test`): 17142 audio clips out of 20371 originally.

You can use the `datasets` library to load this dataset, in which case
the raw audio will be returned along with a sequence of one or more
labels. Note that the raw audio is returned without further processing,
so you will need to decode and possibly downsample the audio for model
training.

Example instance from the `train` subset:
```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']
}
```

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.
