Audio dataloaders

Audidata

Audidata is a toolkit that allows users to easily load audio datasets in less than 5 minutes. Audidata supports music, audio, and speech datasets. Audidata also provides samplers, tokenizers, and transforms. Users can also create their own datasets inside audidata.

0. Installation

python >= 3.9 is required.

Method 1. Download source code (Recomended for developers)

Download source code allows users to edit and create new features for audidata easily.

git clone https://github.com/AudioFans/audidata

Set environment (for each terminal).

cd audidata
export PYTHONPATH=`pwd`  # Export environment path so that users can import audidata anywhere in the terminal.

Method 2. Install via pip (Developing)

pip install git+https://github.com/AudioFans/audidata.git@main

1. Example

Users must download the dataset manually. We provided how the datasets should be structured in each dataset file. Here is an example of loading GTZAN dataset.

from audidata.datasets import GTZAN

root = "/datasets/gtzan"
dataset = GTZAN(root=root, split="train", test_fold=0, sr=16000)
print(dataset[0])

Output:

{'audio_path': '/datasets/gtzan/genres/blues/blues.00010.au', 
'audio': array([[ 0.11234417,  0.13617763,  0.10609552, ..., -0.06634186, -0.07007345, -0.07359146]], dtype=float32), 
'target': array([1., 0., 0., 0., 0., 0., 0., 0., 0., 0.], dtype=float32), 
'label': 'blues'}

For more examples please see audidata/examples. For example, users can run the following example script to concatenate multiple datasets:

python examples/test_concat_datasets.py

Output:

0 dict_keys(['dataset_name', 'audio_path', 'bass', 'drums', 'other', 'vocals', 'accompaniment', 'mixture'])
1 dict_keys(['dataset_name', 'audio_path', 'audio', 'target', 'label'])
2 dict_keys(['dataset_name', 'audio_path', 'bass', 'drums', 'other', 'vocals', 'accompaniment', 'mixture'])
3 dict_keys(['dataset_name', 'audio_path', 'audio', 'target', 'label'])
