### Dataset Summary

GTZAN is a dataset for musical genre classification of audio signals. The dataset consists of 1,000 audio tracks, each of 30 seconds long. It contains 10 genres, each represented by 100 tracks. The tracks are all 22,050Hz Mono 16-bit audio files in WAV format. The genres are: blues, classical, country, disco, hiphop, jazz, metal, pop, reggae, and rock.

*** THIS VERSION OF THE DATASET CONTAINS THE ORIGINAL AUDIO TRACKS SEGMENTED INTO 10 SECOND LONG FILES ***

### Languages

English

## Dataset Structure

GTZAN is distributed as a single dataset without a predefined training and test split. The information below refers to the single `train` split that is assigned by default.

### Data Instances

An example of GTZAN looks as follows:

```python
{
    "file": "/path/to/cache/genres/blues/blues.00000.wav",
    "audio": {
        "path": "/path/to/cache/genres/blues/blues.00000.wav",
        "array": array(
            [
                0.00732422,
                0.01660156,
                0.00762939,
                ...,
                -0.05560303,
                -0.06106567,
                -0.06417847,
            ],
            dtype=float32,
        ),
        "sampling_rate": 22050,
    },
    "genre": 0,
}
```

### Data Fields

The types associated with each of the data fields is as follows:

* `file`: a `string` feature.
* `audio`: an `Audio` feature containing the `path` of the sound file, the decoded waveform in the `array` field, and the `sampling_rate`.
* `genre`: a `ClassLabel` feature.
