ESC50¶

class paddle.audio.datasets. ESC50 ( mode: str = 'train', split: int = 1, feat_type: str = 'raw', archive=None, **kwargs ) [source]

The ESC-50 dataset is a labeled collection of 2000 environmental audio recordings suitable for benchmarking methods of environmental sound classification. The dataset consists of 5-second-long recordings organized into 50 semantical classes (with 40 examples per class)

Reference:: ESC: Dataset for Environmental Sound Classification http://dx.doi.org/10.1145/2733373.2806390

Parameters

mode (str, optional) – It identifies the dataset mode (train or dev). Default:train.
split (int, optional) – It specify the fold of dev dataset. Default:1.
feat_type (str, optional) – It identifies the feature type that user wants to extract of an audio file. Default:raw.
archive (dict, optional) – it tells where to download the audio archive. Default:None.

Returns

Dataset. An instance of ESC50 dataset.
