Args: root (str or Path): The path where the directory ``Libri2Mix`` or ``Libri3Mix`` is stored. Not the path of those directories. subset (str, optional): The subset to use. Options: [``"train-360"``, ``"train-100"``, ``"dev"``, and ``"test"``] (Default: ``"train-360"``). num_speakers (int, optional): The number of speakers, which determines the directories to traverse. The Dataset will traverse ``s1`` to ``sN`` directories to collect N source audios. (Default: 2) sample_rate (int, optional): Sample rate of audio files. The ``sample_rate`` determines which subdirectory the audio are fetched. If any of the audio has a different sample rate, raises ``ValueError``. Options: [8000, 16000] (Default: 8000) task (str, optional): The task of LibriMix. Options: [``"enh_single"``, ``"enh_both"``, ``"sep_clean"``, ``"sep_noisy"``] (Default: ``"sep_clean"``) mode (str, optional): The mode when creating the mixture. If set to ``"min"``, the lengths of mixture and sources are the minimum length of all sources. If set to ``"max"``, the lengths of mixture and sources are zero padded to the maximum length of all sources. Options: [``"min"``, ``"max"``] (Default: ``"min"``) Note: The LibriMix dataset needs to be manually generated.
