mirdata

common loaders for Music Information Retrieval (MIR) datasets. Find the API documentation here.

This library provides tools for working with common MIR datasets, including tools for:

• downloading datasets to a common location and format
• validating that the files for a dataset are all present
• loading annotation files to a common format, consistent with the format required by mir_eval
• parsing track level metadata for detailed evaluations

Installation

To install, simply run:

pip install mirdata

Quick example

import mirdata

orchset = mirdata.initialize('orchset')
orchset.download()  # download the dataset
orchset.validate()  # validate that all the expected files are there

example_track = orchset.choice_track()  # choose a random example track
print(example_track)  # see the available data

See the documentation for more examples and the API reference.
