Dataset classes and functions

This module contains classes and functions for working with datasets.

Features

read_features(path, **kwargs)	Read features from given path into memory.
read_features_iterable(path, **kwargs)	Read features from given path either sequentially or by index.
register_format(suffix, read, write)	Register new read/write functions for a given file format.
write_features(path, features, names[, ...])	Convenience function to write features to given path.

Annotations

read_annotations(filename[, dtype])	Returns a pd.Series containing values for this annotation for each instance, indexed by name.
write_annotations(annotations[, name, path])	Write sorted annotations CSV.

Dataset loading and manipulation

CombinedDataset(*datasets)	A dataset that joins one or more individual datasets together and merges annotations.
CorpusInfo(name, description, annotations, ...)	Defines information about a dataset.
DataLoadConfig(datasets, ...)	Defines a configuration for loading one or more datasets.
DataSelector(subset, groups, ...)	Defines a selection of data to keep.
Dataset(corpus_info[, features, subset, label])	Class representing a generic dataset, consisting of a set of features and optional partitions and annotations.
DatasetConfig(path, features, read_kwargs, ...)	Defines a dataset configuration.
MapGroups([map])	Defined a mapping between categorical groups.
RemoveGroups(drop, keep)	Defines a set of groups to keep or remove from a dataset.
SubsetInfo([clips, description])	Defines a subset of a dataset.
load_datasets_config(config)	Load one or more datasets from a DataLoadConfig.
load_multiple(corpus_files[, features, ...])	Load one or more datasets with the given features.

Utilities

get_audio_paths(path[, absolute])	Given a path to a dir or list of audio files, return a sequence of absolute paths to those files.
resample_audio(paths, dir[, sr, n_jobs])	Resample given audio clips to 16 kHz 16-bit WAV, and place in direcotory given by dir.
resample_rename_clips(mapping[, sr, n_jobs])	Resample given audio clips to 16 kHz 16-bit WAV.
write_filelist(paths, path)	Write sorted file list.
