audb -- Sharing and Versioning of Audio and Annotation Data in Python

Driven by the need for larger and more diverse datasets to pre-train and fine-tune increasingly complex machine learning models, the number of datasets is rapidly growing. audb is an open-source Python library that supports versioning and documentation of audio datasets. It aims to provide a standardized and simple user-interface to publish, maintain, and access the annotations and audio files of a dataset. To efficiently store the data on a server, audb automatically resolves dependencies between versions of a dataset and only uploads newly added or altered files when a new version is published. The library supports partial loading of a dataset and local caching for fast access to already downloaded data. audb is a lightweight library and can be interfaced with any machine learning library. It supports the management of datasets on a single PC, within a university or company, or within a whole research community.
