Audidata

Audidata is a toolkit that allows users to easily load audio datasets. Audidata supports music, audio, and speech datasets. Audidata also provides samplers, tokenizers, and transforms. Users can also create their own datasets, samplers, and transforms based on Audidata.

0. Installation

Method 1.

pip install audidata

Method 1. Download source code

git clone https://github.com/AudioFans/audidata
cd audidata
export PYTHONPATH=`pwd`  # Export environment path so that users can import audidata anywhere in the terminal.

1. Example

Users must download the dataset manually. The datsets should be structured described in dataset files. 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'])
